The 11 Loudest Bluetooth Speakers


Outeraudio has been publishing this list of the hottest, most powerful, and loudest Bluetooth speakers since 2018, and surprisingly, the ultimate winner has not changed in so many years! We only include speakers that are able to match their volume with high-quality audio performance. We understand that everyone’s speaker choices are unique and tailored to their own requirements, so we’ve included some of the loudest portable Bluetooth speakers of all budgets, sizes, and shapes.

The New SOUNDBOKS - Loudest Bluetooth Speaker
Our Top Pick


The Soundboks is the loudest Bluetooth speaker on the market. Delivering a peak volume of 126dB with military-grade batteries providing 40 hours of non-stop beats each.

Editors Note: We constantly curate our content to keep it fresh and relevant. This list was updated on October 29st, 2022, to swap the Soundcore Trance for the W-King on the list. Click here for more information on how we picked these speakers.

Our Category Winners

  • The Loudest Bluetooth SpeakerThe Soundboks Gen3
    The Soundboks Gen 3 stands alone in its magnitude, an unbelievably powerful and large Bluetooth speaker that offers 126dB of volume. The Soundboks Gen 3 size doesn’t make it the most portable option, but if you’re looking for a really loud party speaker for your home or if you’re involved in events management, the Soundboks Gen 3 can do a lot for you.
  • Best Value for Money – W-King T9
    The W-King T9 is the ultimate Bluetooth speaker for those looking for a party speaker on a budget. At around $100, you’ll be treated with the impressive sound provided by the large 4″ woofers and 1.2″ tweeters. With 7 different lighting effects and up to 24 hours of battery life, you’ll be getting a speaker experience that exceeds the price paid. The only real downside to this speaker is that it is not waterproof.
  • Most Rugged Speaker – Turtlebox Gen 2
    The release of the Turtlebox Gen 2 changed the game for portable Bluetooth speakers offering over 115dB of sound. It falls just behind the Soundboks Go in terms of output (120dB vs. 121dB) but dominates in terms of durability. The Turtlebox Gen 2 is surprisingly small and lightweight for its output, and with its IP67 rating, you’d be hard-pressed to find a better option for the outdoors.
  • Most Stylish Loud Speaker – Marshall Woburn II
    The Marshall Woburn II carries the aesthetic of Marshall’s legendary amplifier design and carries it across to a Bluetooth speaker. The Woburn II is one of Marshall’s larger Bluetooth speakers, but with the increased size comes an increase in sound. The Marshall Woburn II is best used, in our opinion, as a dedicated home Bluetooth speaker; it’s a bit large and awkward to travel with but looks great next to the vinyl player in your office.
  • Loudest Small Speaker – Soundcore Motion Boom Plus
    We selected the Motion Boom Plus for its compact size and lightweight (5.03lbs) and the relative loudness for such an easily portable speaker. The Motion Boom Plus still offers more than 95dB of volume, and the combination of loudness and sound quality at under $180 is a tough find in the market.
  • Loudest Portable Speaker – JBL Boombox
    The JBL Boombox has become one of JBLs most popular Bluetooth speakers. This speaker finds that sweet spot between volume, sound quality, and portability. The Boombox is not the lightest speaker at just shy of 11.5lbs, but it is still really easy to carry and has enough power to make its way onto this list.
  • Loudest Smart Speaker – Sonos Move
    The Sonos Move brings modern home smart speaker technology without sacrificing audio. The Move brings around 85dB of volume in what is otherwise a compact and sleek design. The Sonos Move wins our recommendation for a home smart speaker that can still be cranked up.

The 12 Loudest Bluetooth Speakers

These first 3 speakers are the big boys. These large Bluetooth speakers are also some of the loudest Bluetooth speakers on the market today. They all deliver upwards of 100 dB of sound. Even in this small group, there’s a rather large price difference between the speakers.

1. Soundboks (Gen 3)

How Loud is the Soundboks?

At a peak volume of 126dB, the Soundboks (Gen 3) is the loudest portable Bluetooth speaker money can buy. If you’re looking for the loudest most impactful speaker on the market so you can really shake your whole party, this is it. This monster will turn any place you go into the front row at a concert with the turn of a knob.

To put in perspective how loud this speaker is, and it’s hard to comprehend because decibels are plotted on a logarithmic scale, take look at some of the comparisons below.

How Does That Compare?

The perceived loudness of the Soundboks can be best understood by comparing it to some other sounds you may be familiar with, and some of the other speakers on this list. The Soundboks will sound:

  • 1.5 x louder than the Turtlebox Gen 2 (120 dB)
  • 4.5 x louder than the JBL Partybox 310 (104 dB)
  • 11 x louder than the Sony SRS-XB43 (91 dB)
  • 1.5 x louder than a chainsaw at a working distance (120 dB)
  • 3.5 x louder than a helicopter taking off (108 dB)
  • 6 x louder than a jackhammer (100 dB)

What Else has Been Measured at 126 dB?

  • Alice Cooper concert, 25m from speakers (126 dB)
  • Formula 1 in the stands across from the pits (126 dB)
  • Vuvuzela horn used at soccer games (127 dB)
  • Drag racing from the stands (125 dB)
  • Jet taking off 60m away  (125 dB)

How Long Can I Listen to the Soundboks at Full Volume?

You can’t. Don’t do it.  At 126 dB hearing loss and damage will start setting in immediately.

Loud and Proud!

The team at Soundboks hit a home run with this design, this speaker visually looks just as imposing as its technical specs prove it to be. Weighing in at 34 pounds, this speaker is considered portable, but I wouldn’t call it lightweight. The large gauge mesh on the front of the third generation Soundboks openly displays the two 10″ woofers and 1″ tweeter that provide the top-quality music listening experience you will get with this big Bluetooth speaker, and the side panels of this device each have an inlaid durable handle that will make handling this speaker more convenient. 

Inside this speaker, there are 3 separate amps that drive the device with a whopping 216 watts, a lot of power, and a lot of volume. In essence, the Soundboks is just that, a box of sound, and there’s beauty in the simplicity of the product’s message. 

The Soundboks can be purchased with two ‘Batterybokses’ that will power the Sound Boks for 40 hours each. Yeah, you read that correctly, 40 hours! Each battery will provide almost two days of thumping sound with a single charge. Just like the previous generations of the Soundboks, the battery life of the 3rd generation iteration is super impressive. 

Versatile Connectivity

The Soundboks has quite a few connectivity options, including Bluetooth, 3.5mm auxiliary, and XLR combo sockets, and you can even connect up to 5 Soundboks speakers using the built-in SKAA technology, TeamUp.

Aside from loudness, does it sound good?

The Soundboks is the loudest portable Bluetooth speaker out there, but how is the quality compared to the competition? 

This Bluetooth beast has incredible volume, but thankfully, the Soundboks’ insane amplitude is accompanied by high sound quality and a pleasant neutral sound signature. It’s common for giant speakers to have low bass that can muddy up a track, but the Soundboks’ low end is tight and clean with no clicks, pops, or distortion. 

Is it worth the price tag?

The new and improved 3rd generation Soundboks is not for everyone, but you’ll know if it’s for you. This behemoth of a Bluetooth speaker is quite expensive for this sort of product, but some of us just want the best money can buy. It could be determined that the Soundboks Gen3 is an over-the-top piece of gear, but it sure is a whole lot of fun.

This truly is the loudest portable Bluetooth speaker you can get, but of course, if you want the best you need to pay the price. If you’re looking for a bargain you aren’t going to find it here, but for those of you looking for an incredible speaker with a great list of features and connectivity options you have found something special here. 

Along with the Soundboks is an ethos around raw power and rugged fun. Just like the Soundboks’ durable design and adventurous attitude, the kind of music-listening experience you will get with this speaker treads where no speaker has gone before!

Also available from Walmart

So, you want a high-end party speaker that will blast music, but you don’t want to spend enough to pay for a month’s rent, introducing: the Bose S1! The Bose S1 isn’t the loudest Bluetooth speaker on the market, but it is very, very loud. On top of that, it’s not nearly as expensive as its even louder counterparts like the Soundboks. 

Design and Features 

The Bose S1 is big, 15 pounds to be exact. This is a Bluetooth PA speaker that will undoubtedly blow your and your friend’s socks off with its sheer volume at 109 dB peak. Like most Bose products, the S1’s visual design is practical and sleek with a no-frills sort of appeal to it. The speaker is quite sturdy, it is made of very durable plastic, so it will go wherever the party is without any issues and provide you with music for 11 hours on a single charge.

The S1’s built-in sensors and directional sound output features will ensure that no matter where you place this speaker the sound experience you have will be top-of-the-line. You can even pair two of these speakers together for a stereo PA setup, completely wireless!

This is a high-end, fully-featured Bluetooth speaker with awesome extras like Auto-EQ technology and ToneMatch processing that will ensure any audio that this speaker plays will sound great. If you want more control over your sound, this speaker has two built-in 3-channel mixers and integrated EQ and reverb processing. 

Audio Connections

The connection capabilities with the Bose S1 Bluetooth PA are one of this speaker’s strengths, this speaker has two XLR/1/4-inch auxiliary jacks for instrument or microphone connections in addition to its Bluetooth connectivity. There is also a 3.5mm aux port in the rear of the speaker for easy wired mobile connections. 

How Does It Sound?

The Bose S1 offers very high-quality audio at deafening volumes, and if you want your music any louder, you’ll need to pay quite a bit more for it. You can easily fill an entire home with music with this speaker and if you have two you will have access to one of the cleanest and most impactful music listening experiences within this size and price range. 

There are similarly priced JBL speakers that can get you more bass than this speaker provides, but if you are looking for a loud, quality listening experience from a compact speaker then the Bose S1 may be just what you’re looking for. 


In conclusion, the Bose S1 Bluetooth PA speaker is a fantastic audio solution for parties, gatherings, or home audio if you are looking for intense volume and great quality but don’t want to spend the extra money for the highest the high-end has to offer. This speaker could definitely be described as a mid-tier high-end speaker, but don’t let that fool you, this is a fully-featured speaker that can provide music for any gathering of fewer than 100 people. 


  • High-Quality Audio
  • Affordable High-End Option
  • Auto-EQ Technology


  • Mediocre Battery Life

99 dB

200+ W

Also available from Walmart

If you’re looking for a reliable Bluetooth speaker capable of delivering loud, bass-heavy sound with some additional party-friendly features. Take a look at ç Bluetooth Speaker. Featuring louder sound, a larger enclosure, and improved battery life, the XP700 is the party lover’s upgrade from the XP500 Bluetooth Speaker.

A Portable Speaker with Great Battery Life!

The Sony SRS XP700 Bluetooth Speaker is a powerful speaker housed within a portable and easy-to-carry cabinet, designed to follow you wherever the party takes you. It can be situated either upright or on its side and a built-in sensor adjusts audio projection accordingly to provide optimal sound quality.

For house parties, camping, or beach adventures, the SRS XP700 can provide up to 25 hours of playtime, while a 10-minute quick charge will enable the speaker to perform for 3 hours nonstop. This is a considerable upgrade from Sony’s SRS XP500 model, which is capable of a 20-hour playtime and only 80 minutes of operation on a 10-minute charge. 

The Sony Music Center App or Fiestable App allows you to control the speaker’s onboard lights, create playlists, customize audio characteristics and gain other general control over the speaker from any smart device. An IPX4 splash rating means gentle splashes from the pool, lake, rain or careless beverage consumers won’t affect the speaker’s operations and the party can continue safely. 

Plenty of Connections and Features

The Sony SRS XP700 can stream audio via Bluetooth technology from any Bluetooth-enabled device, and a USB device or flash drive can be inserted to access stored files for playback. A mic or guitar can also be connected to the XP700, allowing you and your friends to jam along to your favorite karaoke tracks, or use the speaker as a portable, battery-powered guitar amplifier. 

Loud Sound with Mega Bass!

Aside from being an insanely loud Bluetooth speaker, capable of reaching volumes comparable to a loud motorcycle or gunshot, the XP700 features front and rear-mounted tweeters, providing multi-directional sound capable of filling any room or outdoor area with loud, colorful sound.

X-Balanced speaker units also produce tight, punchy bass- perfect for any style of music. This ‘Mega Bass’ feature can be controlled using the button on top of the speaker. If you’re looking to host a larger-scale party where one dancefloor just won’t be enough- you can link up to 100 XP700 speakers together, creating your own concert-like speaker system.

Why You Should Consider This Speaker

While the XP700 is aimed towards party-goers and large crowd gatherings, this Sony Bluetooth Speaker can certainly be tamed to fit your living room, bedroom, kitchen, or office with its versatile features and all-round great sound quality, perfect for any style of music. Whether you’re looking for something portable or fixed, loud and fun, the Sony SRS XP700 is the Bluetooth Speaker for you. A long battery life, paired with eco and energy-saving features such as standby modes and battery preservation functions guarantees a long-lasting and reliable Bluetooth Speaker.

If you fancy the look of this speaker but don’t necessarily need all the volume, take a look at the XP500 model- while its battery life is slightly shorter and the speaker itself is smaller, it shares the rest of the unique features and functions with the XP700 including connectivity, speaker pairing, mega bass function and control via the mobile applications.

The Loudest Portable Bluetooth Speakers

The following set of Bluetooth speakers is still extremely loud, with the Turtlebox being just a few decibels short of the Soundboks 3. However, despite how much volume they produce, these are still what we would consider more portable alternatives to the larger speakers listed above.

4. Turtlebox Gen 2

Turtlebox Gen 2

120 dB

85 W

25 hrs

10 lbs


Also available from Walmart

The makers of the Turtlebox recently launched their second generation of this popular outdoor speaker. Presented as an “outdoor rugged Bluetooth speaker”, and you have to take but one look at the design to believe that they’re as serious about this claim today as they were at its inception

The one other standout feature they seem to be equally proud of is the fact that it is LOUD!  At 120 dB the Turtlebox Gen2 is nothing to be sniffed at.  It is hands-down the loudest Bluetooth speaker in its weight class.  But is it worth investing in such a radically different approach to speaker design?  Let’s take a look at what you get.

Designed for The Outdoors

The design of the Turtlebox is different, though not completely unique, in that at a first glance you’ll be forgiven to think the makers took a hard-shell case, commonly used to protect and waterproof outdoor gear and camera equipment, and built a speaker in it.  That “rugged” look is at the core of the Turtlebox concept though.  It is very tough.  The IP67 Turtlebox shell is waterproof, dustproof, and shock-resistant and is intended to handle anything the elements throw at it.

If you combine that with a long-life battery that will play for 25 hrs at “listening volume” and 6 hours at full volume you have a very desirable Bluetooth speaker.

Audio Connections

Besides Bluetooth connectivity, the speaker also comes with an AUX cord and 3.5 mm input for those who prefer a direct line from their music source to the speaker. There’s a jack for a mic if you feel like getting into the mix yourself. The Turtelbox also sports a USB-C port that you can use to load your other devices.

The difference between the original Turtlebox and the Gen 2 version is that the USB-C “in” port has been dropped, but Turtlebox upgraded the Bluetooth connectivity from v4.2 to v5, giving you more stability and added rage. The newly designed port compartment is also slicker and better integrated into our opinion.

How Does it Sound?

Now for the best part.  For a package, this small, delivering these kinds of volumes the sound quality is actually quite outstanding.  There are almost no distortion and no DSP that lowers sound level at max volume. The lows are rich and it does a great job at keeping the mids and highs balanced at the same time.  It’s an all-around great speaker to listen to.

The Turtlebox sound curve has been fine-tuned specifically for outdoor listening, and a large part of this is making sure you can play this speaker at loud volumes that will cut through the wind and outside noise, yet still enjoy crisp and well-defined tones.

Your Turtlebox can be paired with a second Turtlebox to create a true stereo effect if that’s what you need, but we think one of these will suffice for most scenarios.  


The Turtlebox Gen 2 is one of those products that seem to deliver on almost every claim it makes. It is loud and it sounds great.  The design concept may not be to everyone’s taste but we like that Turtlebox is unapologetically targeting a specific market, and not trying to be everything to everyone.  We think they’re nailing it.

  • Rugged and Honest


  • Relatively short battery life

5. W-King T9

W-King T9

105 dB

80 W

24 hrs

9.6 lbs


The W-King T9 is an impressive speaker that offers all the features we look for in a party speaker, at an affordable price point. With a maximum output of 105dB, the W-King earns its spot on this list. We’ve selected this speaker primarily for its portability and affordability. The T9 is available for a fraction of the price of other speakers on this list and in some cases even pushes more volume.

Big Drivers, Small Size

The T9’s impressive sound is driven by its combination of two 4” woofers, which are able to provide a rich bass response, while two 1.2” tweeters bring life to the high end of this speaker. We’re often hesitant to recommend speakers from fairly small manufacturers, as we often find the audio quality isn’t where we’d like to see it.

This is not the case with the W-King T9. For an affordable speaker, W-King has managed to create a product that can play alongside larger established brands. You won’t find an excessively muddy bass on this speaker, with the mid-tones and upper lows still being reasonably separate in the presentation.

The mids and highs are fairly crisp, and while you won’t get Sony XP700-type clarity, the W-King still stands tall in its price bracket, bringing hard-to-beat bang for your buck, especially in the audio department.

Bluetooth 5.2 Connectivity

In terms of connectivity, the W-King T9 utilizes modern Bluetooth 5.2 codecs, providing better compressions and overall enhanced performance, especially at range. On the back of the speaker, there are a few inputs and outputs; these include a standard USB connection, a 3.5mm aux out, a USB-C connection, and a TF Card slot. We like to see the inclusion of both USB-A and USB-C types, but it would have been really nice to see a microphone input, as this speaker design would lend itself well to a home karaoke speaker.

Sturdy Build & Loads of Battery Life

The T9 also brings a fairly rugged construction to the table with a matte shell that feels like it could take a few knocks, along with an iron mesh covering the drive cones. Even with the two large woofers driving this speaker, W-King has managed to keep the weight below 10lbs, making it a great option to take with you to friends or family gatherings.

In addition to the weight, the speaker features a carry handle which makes transport that much easier. 

A nice-to-have feature on this speaker is the addition of resting blocks on the side of the speaker that allows you to lay it down on its side so that the drivers align horizontally. This may not seem like much, but it can help in creating a slightly wider sound, especially indoors.

The lighting effects on the T9 are excellent, with 7 different light modes that can easily be controlled so that you can bring life to the party with some ambiance. 

The battery life on the W-King is around 24 hours at lower listening volumes, but even during standard listening volumes for you and a group of friends, you’re likely going to still see around 8 hours from this speaker, which is enough for most typical use scenarios. The speaker can also be played while charging – reducing the number of times you’ll need to rely on the battery life.

Unfortunately, the one area where this speaker lacks – is waterproofing. The T9 is not waterproof, and we do not recommend using this outside during any rain. It would probably be fine several feet from the pool, but we do recommend being careful with the T9 around any water.

If you’re in the market for a loud Bluetooth speaker on a budget, the T9 will have you covered. For around $100 you’ll get over 100dB of sound, multiple lighting effects, and a well-built speaker.


  • Affordable
  • Impressive lighting effects
  • Punchy bass
  • Bluetooth 5.2


  • Lack of waterproofing
  • No mic-in

6. JBL Boombox 2

JBL Boombox 2

100+ dB

80 W

24 hrs

11.6 lbs


Also available from Walmart

Another offering from JBL boasts loud sound quality along with portability, waterproof features, and impressive battery life.

Easy to Carry, Waterproof, and LOUD!

The compact size and light weight of the JBL Boombox 2 allow for easy transportation to the park, beach, or any other outdoor activity and can comfortably fit into a backpack or beach bag. A waterproof rating of IPX7 means the Boombox can be confidently taken to the beach or poolside and will survive rain, splashing, spills and even a short submersion underwater. 

JBL’s Boombox 2 features a rechargeable Li-Lion battery that supports up to 24 hours of playtime on a single charge, and can even function as a power bank, capable of charging up to 2 USB-chargeable devices at a time. 

Multiple Devices Either Way

The JBL Boombox 2 allows for up to 2 smart devices to connect to the speaker at any time, while the one streams music to the speaker, the other does not lose connection and can override the content at any time.

JBL devices that are compatible with JBL Connect+ allow for up to 100 speakers to link with one another, providing louder, fuller sound across the entire house, garden, beach, or park. In addition to the Bluetooth capabilities of the Boombox, one can also connect using a 3.5mm auxiliary cable, and the Boombox can operate on battery or while connected to an outlet for unlimited playtime. 

Monstrous, Versatile Sound 

The JBL Boombox 2 features a unique sound mode feature allowing for control over two settings: indoor and outdoor mode. I noticed that the indoor mode provides a warmer, well-rounded, and full-bodied sound with deeper bass, while the outdoor mode is slightly more expansive with a large dynamic range, powerful bass response, and crystal clear higher frequencies. 

The JBL Boombox 2 features 4 active transducers and 2 bass radiators, permitting immersive sound quality and hard-hitting bass that you can not only hear and feel but physically see the speaker’s movement. 


  • Easy to carry
  • Incredibly loud for its size
  • Able to charge other devices
  • Great battery life


  • For the price, there are louder options out there

7. Ultimate Ears Hyperboom

Ultimate Ears Hyperboom

100 dB

229 W

24 hrs

13 lbs


Also available from Walmart

The biggest and baddest in Ultimate Ears’ ‘Boom’ range of Bluetooth speakers consists of the Wonderboom, Boom 3, Megaboom, and Hyperboom. The Hyperboom is an all-around upgrade of the previously mentioned models, however, if this speaker is a little too excessive for your current needs, take a look at the rest of the range as Ultimate Ears really have catered for everyone on this one. 

Cross-Compatible, User-Friendly, and Portable

All of Ultimate Ears’ devices in the ‘Boom’ range of Bluetooth speakers can connect to one another for enhanced and effectively, louder, sound. Easy-to-use buttons on top of the Hyperboom make the speaker’s functions very straightforward to navigate, and extra features can be controlled using the app.

Up to 4 devices can be connected to the Hyperboom at once using Bluetooth, auxiliary and optical inputs. Additionally, the USB output allows you to charge your phone using the Hyperboom’s battery without interrupting music playback.

While the 24hr battery life of the Hyperboom may not be as impressive as some other items on this list, it really is, in my opinion, all you need for a great party or relaxed gathering at the beach, garden, or poolside. The Ultimate Ears Hyperboom also features a carry strap, making transporting the speaker a breeze!

A waterproof rating of IPX4 allows for a reasonable level of weatherproofing from basic elements such as rain, mist, splashing pool water, or the occasional spilled drink.  

Adaptive EQ makes it perfect for any setting

At this point, we are already aware that the Ultimate Ears is capable of rattling the window frames at your house party. When looking at the overall quality of audio produced by this Bluetooth speaker, there really is nothing to complain about here.

The Hyperboom uses cutting-edge adaptive equalization technology, making use of an onboard microphone to analyze reflections and resonances around the speaker to in turn re-shape the tonal qualities of the speaker- always providing perfect sound no matter where you place your Hyperboom. Another impressive feature of this speaker is its ability to maintain clear sound quality and tight low-end response at all listening levels. 

Great Value for Money

Available at just short of 400 bucks, the Ultimate Ears Hyperboom promises to provide long-lasting memories on the dancefloor, pool deck, or home bar. Its professional aesthetic makes it a great choice for those looking for a portable speaker that can remain in a fixed position when not in use and still look like part of the room, and a long Bluetooth range means for easy and uninterrupted use anywhere in your home or garden.

  • Adaptive EQ provides perfect sound in any setting
  • Easy to use, compatible with virtually any device
  • Decent battery strength can charge other devices


  • Lacks extra features such as karaoke
  • Optical input is quite unnecessary

8. Marshall Woburn II

Marshall Woburn II
  • The Most Stylish Loud Bluetooth Speaker

110 dB

110 W

AC only

18.9 lbs


Also available from Walmart

Known worldwide as manufacturers of some of the best guitar and bass amplifiers in music history, with their products seen on stage alongside some of our favorite superstars, Marshall broke into the home audio market with a range of Bluetooth speakers. Here we’ll be taking a look at the largest and most recent release of the range, the Woburn II.

Elegant, Authentic, and Loud

With the Woburn II, Marshall sticks to its heritage of delivering ear-splitting, vibrant, heavy rocking sounds from devices of all styles and sizes. The Woburn II holds 2 x 5.25” subwoofers and 2 x 1” tweeters, individually powered by class D amplifiers to deliver larger-than-life sound, housed within Marshall’s iconic textured vinyl cabinet. 

The elegant design of the Woburn II makes for a classy addition to your living room, bedside table, or kitchen countertop and can comfortably fill any room with powerful, window-rattling sound with ease. Furthermore, the Woburn II features a 2-band equalizer to fine-tune the tonal characteristic of your music to suit the shape, size, and features of your room, or just enhance the bass response or high-frequency clarity if that’s what you’re looking for. 

Quick Setup and Easy to Use

The Marshall Woburn II can accommodate playback from a variety of sources including Bluetooth 5.0 (with aptX) 3.5mm auxiliary cable or RCA. Input modes can be toggled using a switch on top of the speaker, and a similar play/pause switch can be found on the other side of the rotary dials that resemble the knobs of a classic Marshall amp. To control the power of the Woburn II, simply flick the lever on the far right of the control panel to unleash a classic, LOUD, Marshall tone. 

The Bluetooth strength of the Woburn II is fair enough for use within your home, however, if you plan to have control over the speaker from the opposite end of a large garden area, expect some signal breakups or delays. Multi-host Bluetooth features are supported here, allowing two devices to connect to the Woburn II at any given time. As for other connectivity options, I am quite surprised to see the lack of a guitar input jack, considering it is a common addition to many loud Bluetooth speakers, and Marshall is one of the greatest guitar amplifier manufacturers. 

Sounds Great with All Music Styles

While it may be assumed that the Woburn II is designed for Rock and heavier music types, this Marshall Bluetooth speaker surprisingly manages other music styles incredibly well. The punchy bass response allows for dance and hip-hop fans to move their bodies to the beat, while well-defined high-frequency content provides crystal-clear pop vocals and gentle piano and guitar-based joy. When the volume levels of the Woburn II were put to the test, aside from reaching shockingly loud volumes, a strong sense of definition was present throughout. 


  • Beautiful-looking speaker
  • Loud and versatile


  • No battery power
  • No ‘Smart’ features

The Loudest Small Bluetooth Speakers

In the last part of this article, we’ve included relatively small but loud Bluetooth speakers. Although small, these speakers still pack a punch! Small Bluetooth speakers which are still capable of putting out large sound make for great everyday speakers that you can take with you to friends’ houses or quickly grab and take outside to the pool while you swim.

9. Anker Soundcore Motion Boom Plus

The 11 Loudest Bluetooth Speakers 1

95 dB


20 hrs

4.41 lbs


Also available from Walmart

From one of our favorite speaker manufacturers, Anker, the latest version of the beloved Motion Boom bestows loud and powerful sound and an array of handy features to those looking for a compact party speaker. 

The Motion Boom Plus is a touch larger than its predecessor, though its upgraded features and, of course, volume capabilities make up for the added weight and dimensions. Aside from slightly larger size, the two speakers appear virtually the same, except the Plus comes with a carry strap and an integrated handle.   

New Pairing & Impressive Volume

A pair of 30W woofers and a 10W tweeter work together to deliver not only loud but well-rounded and crisp sound at all volumes. While the potential output level of the Motion Boom Plus is greater than double that of the regular Motion Boom Bluetooth speaker, a few hours (4 to be exact) of battery life have been sacrificed for the additional oomph. 

The Motion Boom Plus also brings a new pairing mode to the table. Where the Motion Boom only offered TWS pairing, the Motion Boom Plus has added PartyCast 2.0 support, allowing you to pair it with a wider range of Soundcore speakers.

Now With IP67 Weather-Proofing

In addition to volume and power upgrades, the Motion Boom Plus is a little more weather-resistant, holding an IPX rating of IP67, as opposed to the original Motion Boom’s IPX7 rating. This adds dust, rust, sand, and snow protection to the already 100% waterproof grade, making this another ‘everything proof’ Bluetooth speaker.

The Bluetooth codec also saw a massive upgrade, jumping from the already impressive 5.0 transmission code to 5.3, promoting stronger connections, as well as the addition of a 3.5mm auxiliary input for wired connectivity. The Motion Boom Plus can also charge USB-powered from its own battery, though this will severely shorten the already weak battery life of the speaker. 

The Soundcore app can be downloaded to any smartphone and is used to perform firmware updates and control the speaker’s sound signature, as well as additional features such as speaker pairing for stereo pairs or party systems.


  • Easily transportable yet incredibly loud
  • Bluetooth 5.3
  • Excellent waterproofing
  • PartyCast 2.0 support


  • Soundquality at higher volumes could be clearer
  • Average battery life

One of our favorite home audio manufacturers, Sonos, delivers a compact yet powerful Bluetooth speaker that has yet again impressed us with jam-packed features and versatility. 

Smart Features and a Breeze to Control!

The Sonos Move can be set up and paired within a matter of seconds and comes pre-loaded with your standard smart features including WiFi connectivity for wireless data streaming, Bluetooth functionality, and voice control. Amazon’s Alexa comes included with the Sonos Move, allowing you to play music, catch up on the news, set alarms, or have your wildest questions answered all without moving a finger. The Sonos mobile app allows for further ease of control, and AirPlay 2 technology provides for quick and painless pairing with Apple devices. 

Durable Design Makes For Stress-Free Use

The Sonos Move wireless Bluetooth speaker is housed within a hard-wearing, shock-resistant case, protecting the speaker from accidental drops or knocks. No need to stress when rocking the neighborhood with your afternoon tunes by the pool, as any unexpected conditions such as rain, snow, dust, and humidity aren’t an issue thanks to IP56 weatherproof features. The Move is also beach-friendly as it is hard enough to handle salt spray, and can also be used in temperatures ranging from back-breaking cold to brow-wiping heat. 

Tiny Speaker, Massive Sound

Measuring in at an exaggerated 10 x 6.5 x 5 inches, the Sonos Move is easily transported within a beach bag, backpack, or handbag and for its small size, manages to produce incredibly loud sound!

The Move uses soundstage analysis software known as TruePlay to evaluate the speaker’s surroundings and the music you’re playing through it to adjust the frequency characteristics in order to provide the biggest, loudest, and most immersive sounds from its tiny enclosure. 


  • Portable and lightweight
  • Voice Control and WiFi compatible


  • Relatively short battery life
  • No option to charge other devices
  • No alternative connections other than Bluetooth

11. Sony SRS-XB43

Sony makes another appearance on our loudest Bluetooth speakers list with another product from the SRS range, this time with the far more compact XB43. This backpack-friendly model in the SRS range is capable of many of the same modern features and functions as the XP700 model we discussed earlier. 

Extra Small, Extra Bass

Sony’s X-Balanced speaker design gives these compact speakers a powerful bass boost, this, coupled with the Live Sound Mode feature can take your backyard gathering from a house party to a mini-festival of its own, creating a three-dimensional sound experience. If you’re looking to turn it up a notch, the Fiestable app from Sony allows for up to 100 compatible speakers to be paired to one another, generating some firework-like volumes that’ll surely make your house party the talk of the town.  

Side-mounted passive radiators provide thumping bass, while the dedicated tweeter makes sure the highest of highs remain clear and unmuffled no matter how loud you crank the volume, and the array-like speaker configuration allows for either upright or horizontal placements. 

The XB43 is not only the most powerful of its kind but is also incredibly durable as the IP67 waterproof rating means the worry of small amounts of water or dust affecting the speaker’s delicate components won’t be a concern!

Modern Features Make Life Easier

Compatible with Bluetooth NFC technology, pairing takes only a couple of seconds before the XB43 is ready to unleash monumentally loud sounds and get the party officially started. If you’re not the party type and are simply looking for something suitable for home office use, the XB43’s onboard microphone allows for crisp, dynamic, and clear calls between friends or virtual meetings.

All features on the Xb43 can be controlled by the onboard buttons, and the Fiestable app gives you further control over the speaker from the home screen of your smartphone by using an array of hand gestures. The app also allows you to control lighting modes on the speaker to set the perfect mood for your meeting, movie night, or house party. 


  • Small yet LOUD
  • Easy to set up and control
  • Built-in microphone


  • No control over EQ
  • No additional inputs

The Loudness of Our Selection

So how do the loudest Bluetooth speakers stack up against each other when we compare their decibels?  We’ve literally done that for you in the graph below.  This should give you a good idea of the relative decibel output of each speaker on our list in relation to the others.  You’ll see that, surprisingly, when you look at measured decibels, the numbers for some of the smaller speakers do not differ that much from the bigger ones. There is a plot twist though, so read on.

Volume in Decibels (dB)

Volume is listed in dB as published or confirmed by independent 3rd party tests.

Our Perception of Loudness

Plot twist. Putting a value to loudness as we humans hear it is a lot more complex than the sound pressure level (SPL) numbers published by manufacturers, which is measured in decibels (dB) with acoustical instruments. A decibel is an objective logarithmic measuring unit of sound pressure.

“Loudness”, or our perception of loudness and “volume” are psychoacoustical terms.  It describes subjective sound-sensations, and measuring them is fraught with ambiguity.

That does not mean the decibel specs on your speaker are completely useless, though. It simply means that understanding their impact on how loud your ear will perceive the speaker to be, is a lot more complex than thinking a 100 dB speaker is twice as loud as a 50 dB speaker.  Not even close!

Our perception of how loud a speaker sound doubles every time you increase the output by 10 dB.  A 100 dB speaker will sound twice as loud as a 90 dB speaker to your ear.  A 120 dB speaker will sound four times as loud as a 100 dB speaker and eight times louder than a 90 dB speaker!

And this is where you start to understand just how LOUD the Soundboks will sound, even by comparison to some big speakers on here.    Here’s the graph from above again, but this time we’re plotting the increase in perceived loudness using the speaker with the lowest dB output as a baseline. The Soundboks will sound more than 11 times louder than the Sony SRS-XB43.

Do You Understand Loudness?

How much louder will a 100 dB speaker sound than a 50 dB speaker??

How Did We Pick These Speakers?

Every speaker on this list delivers more than 90 dB in volume. Because this article is about loud Bluetooth speakers, we set that as the minimum threshold to be considered.

When creating this list of the loudest Bluetooth speakers, we carefully scoured through dozens of popular products and chose only the best to recommend. While not every loud Bluetooth speaker made the list, we did try to include the highest quality while also taking your budget constraints and intentions into account.

We understand that volume is important to you. You may also be limited by budget, space, or local availability. Because of this, you’ll find that our selections range from speakers that are small, portable, and affordable to some absolute monsters that could cost upwards of a thousand dollars. We also went through the process of ensuring that volume wasn’t the sole focus and all of the products listed had to also perform well at those high volumes.

One of the limitations or challenges of driver design is that most speakers notoriously start distorting their sound and lose quality as you crank up the volume.  We’re selecting speakers that will deliver crisp undistorted lows, mids, and highs when performing at top volume.

Comparing Apples to Apples

We see plenty of lists on the internet where people simply bundle every available loud Bluetooth speaker into a single list and pick the one that kicks out the most Watts. That’s not quite fair (or very useful), as you’re not really comparing apples to apples. While it’s often true that a large Bluetooth speaker is also a loud Bluetooth speaker, it is not always the case. We wanted to provide a more balanced approach, so we took the loudest Bluetooth speakers from our list and divided them into three weight classes. Take a look at the images below:

loudest bluetooth speaker sizes

It’s safe to say that comparing the third-generation Soundboks to the Soundcore Motion Boom makes little sense. The amount and size of woofers, tweeters, passive bass radiators, and active drivers that you can fit into a 34 lbs vs. a sub 1 lbs package are just not comparable. So, we’ve split our list of the loudest Bluetooth speakers above into 3 groups:

Large and Loud – These are big Bluetooth speakers. They are large, bulky, and built for sound. Clearly not made with portability in mind. While most of our selection can be picked up and carried relatively easily, they are not the type of speakers you just throw in your backpack and head off to the beach. These are big speakers which have the potential to make enough noise for a house party. These types of speakers are ideal if you have a large dedicated entertainment area in your home, for instance.

Solid Mid-Size – These are the everyday speakers you’d have in and around your house. You can easily carry them from one room to another or even outdoors. While they’re portable, they are slightly larger than our petite speakers and therefore pack more of a punch and generally deliver a better sound. Chances are, this is the speaker you want to be listening to every day.

Petite yet Powerful – These are small, but they are still among the loudest Bluetooth speakers on the market, especially when looked at in relation to their smaller scale. They are compact portable Bluetooth speakers which still manage to surprise with their pronounced sound. Toss them in your backpack, take them to the beach, camping, on your bike, wherever.

1. The Move to Bluetooth 5

It feels like Bluetooth speakers have come a long way in such a short space of time. The most significant improvement for Bluetooth speakers is the release of Bluetooth version 5.3. While the technology has been around for some time, we’re now seeing more Bluetooth speakers adopt the new wireless technology en masse. Read this article for a rundown of some of the key features of Bluetooth version 5.3.

2. WiFi and Bluetooth Connectivity

Bluetooth still remains the wireless technology of choice for brands, but we are seeing some Bluetooth speakers include WiFi connectivity too. The proliferation of smart speakers has made it more desirable to be able to connect your speaker to your home network and pair it with the likes of Alexa and Siri.

3. Improved Battery Life

One feature which continues to improve is battery life. It wasn’t long ago that 10 hours of battery life was the best you could get. Now speakers are getting upwards of 20 hours, with some Bluetooth speakers managing 40 hours plus.

Another spin-off feature of improving battery technology is that many Bluetooth speakers no also double as a power bank to charge your other devices.

4. Better Sound Quality

Sound quality continues to improve. Brands like JBL, SOUNDBOKS, Bose, and Sony continue to deliver on sound quality. These brands do charge a premium, but the quality is far superior to the budget end of the Bluetooth speaker market. Having said that, even though budget Bluetooth speakers are sounding better with every release, the W-King T9 is a good example of an affordable speaker punching above its weight.

5. There’s An APP For It

More and more brands are releasing apps for their speakers. Even at the budget end of the spectrum. Through these apps, you can often access settings and features which cannot be accessed using the speaker’s onboard controls.

6. Mic Included

Speakerphone technology is improving and in some cases, getting worse. Even the premium brands battle to get this right. We have noticed several products have chosen to drop the speakerphone feature altogether. I think this is a wise option. I would rather have that money go into features we actually use.

Having said that, the built-in microphone is useful for accessing voice assistants like Alexa, Siri, Google Assistant, Bixby, and others. More and more Bluetooth speakers are also including Alexa integration with the ability to connect with Echo devices. It won’t be long until many of these speakers have Amazon Alexa built-in.

19 thoughts on “The 11 Loudest Bluetooth Speakers”

    • Kenneth – we have indeed! We left it out on our original list because it was so next level (price-wise as well) from the other contenders You’ll be happy to hear we’ve included a special section about the Devialet Phantom at the bottom of the article now. Check out the video. Love that guy!

  1. My favourite blue tooth speaker so far is my anchor soundcore 2. Compact, long battery life good sound and doubles as a charger. Waterproof and shock resestant as well.

  2. I still really like my old BOSE Wave Music System. It didn’t come with bluetooth, but did come with a bluetooth receiver that you plugged into it. It plays music from my devices very well. The sound is really good.

  3. We have a little Bose speaker that seems to be doing the job for us right now (well, it’s my daughter’s actually …!), but I haven’t got anything to compare it against!

  4. So on the recommendation of a friend we got an earlier-version of the Oontz shown here…and wow! The sound quality is great, and we’ve had very long playing times. Another to take to the beach would be perfect!

  5. I like the Anker Soundcore 2! I prefer something easy to carry around! I can bring it to the beach, toss it in the car for road trips, etc. without sacrificing volume!

  6. I love my UE Roll 2! I take it with me anywhere I go, lot battery life, ok sound. I can strap it to anything, my kayak, backpack, mountain bike handlebars. It comes with a small life floatie for it to take in the pool. Just an all around great speaker. You can even connect 2 together for better sound.

  7. My boyfriend has a OontZ Angle 3 portable speaker and we love it. We take this speaker with us whenever we travel because it is so small and portable. I use it every time I shower or go on an outing because the sound quality is loud enough to hear over other noises. It is easy to use and wireless which makes it so convenient for us to use with our mobile devices. In addition, the battery life is great. It lasts us weeks at a time without charging. Lastly, the price of the speaker is very reasonable for the amazing quality. Thank you for this opportunity!

  8. I have owned the OontZ Angle 3 speaker for several years and it is fantastic. Its very small build quality is convenient for portability and sleek design with nice silicone end pieces. The speaker has excellent sound with surprisingly good bass. The big surprise is the volume. I can take a shower and still hear the sound quality perfectly over the noise of the running water. The battery life is great, and it doesn’t lose much over time either. I use the speaker on every travel expedition I take from cruises, to family getaways, to an outing to the beach with my girlfriend. We love this speaker and would love the opportunity to have another one! Thank you!

  9. From the list my favourite would have to be Anker Soundcore 2 Bluetooth Speaker because it’s the lightest; I’ve scoliosis so I only carry lightweight things.

    I’ve a speaker gifted to my by my bosses. I like it so far because I can plug-in a memory card, it’s with a bluetooth function, has blue light (though I prefer it to be red light for sleep; I’m a child care worker), it’s bottom has anti-slip thing(when we clean it before and after setting it down on a surface), and it’s very affordable (elementary school student price)

  10. I’m looking for a Bluetooth speaker that is compact yet has premium features. Quality construction is important. Of course decent power is important. Being able to deliver a rich tone is paramount to my wishes. I would want a high end speaker with all the trappings one would expect. That includes WiF, AirPlay, Spotify Connect and Web Radio. A long-lasting battery would be great. I would be listening to the speed and transfer of the speaker and it’s ability to maintain the desired frequency. I would love a built in microphone and Alexa enabled feature.

  11. What I’m looking for in a Bluetooth speaker is sound quality, durability, reliability, an aesthetically pleasing design, reasonable cost, long battery life, short charge time, and a neutral sound signature. Good sound range is also important to me, I want one that can play the deepest bass as well as the high notes. I also need one that is easy to use and doesn’t have complicated controls. A mobile app would be nice but isn’t a dealbreaker for me. A good warranty would be another plus but I wouldn’t consider it absolutely necessary. Being waterproof would be great. I would also like Wi-Fi connectivity.

  12. Best article on the internet about portable speakers in 2020, PERIOD.

    By the way, there is a typo “Battey” instead of “Battery” on a few of the speaker profiles.

      • I have checked a few of these online forums for the best speaker, Why doesn’t anyone have the monster super blaster on their lists? This speaker is absolutely amazing. It’s high priced and heavy but so worth it. Have you checked this speaker out? Thanks for all you hard work and letting us know which ones are your best, I’m going to check into a couple of these to see how they compare to what I already have.

  13. Hi have just received my Soundcore Mini 3.Am a young music loving 72 year old and this is a brilliant piece of kit for listening to my music collection on my phone.To get a good stereo sound would buying another of these do the trick?.One criticism is the very limited data supplied with it.Not able to understand the full capability of the the Multifunction button?.As you can tell my technology knowledge is basic and would like more details.
