The Loudest JBL Bluetooth Speakers

-

JBL Bluetooth speakers are known for their consistently brilliant sound quality, reliable builds, and modern features and technology. They manufacture speakers ranging from those that fit in the palm of your hand to speakers that are taller than some of us.

JBL Bluetooth speakers always find a way onto our best lists since they’re not only incredibly well-made but no matter the intended purpose, there’s always a JBL speaker that fits the brief. In this list, we look at the loudest JBL Bluetooth speakers on the market, broken down into three specific size formats.

The Loudest JBL Bluetooth Speakers 1
JBL PartyBox 1000

Possibly the loudest commercial Bluetooth speaker on the market, the JBL PartyBox 1000 will rattle windows, floors and perhaps even the walls.

Our Top Picks

Loudest JBL Bluetooth Party Speaker

The JBL Partybox 1000 is the ultimate beast of Bluetooth speakers. It lacks the portability of the other designs, but if you’re purely going for volume, you’ll be hard-pressed to find any Bluetooth speaker on the market that brings more to the table.

Loudest Portable JBL Bluetooth Speaker

When it comes to easily portable products from JBL. The Boombox 2 is going to give you the best volume and sound quality. This speaker is slightly larger than most other portable JBL Bluetooth speakers, we selected the Boombox 2 because of its balance in versatility and loudness.

Loudest Compact JBL Bluetooth Speaker

We recommend the JBL Flip 6 if you’re looking for something you can fit into your backpack or carry with you easily with your buddies down to the beach or have around during your next hang out. The Clip series offers a smaller alternative, but the Flip 6 has so much to bring to the table that it’s tough not to recommend it, with its high-quality sound, weather protection, and latest features.

We’ve gone pretty deep down the loudness rabbit hole, and since JBL speakers make regular appearances, particularly for loudness, here are our favorite loudest JBL Bluetooth speakers. The speakers are divided into three main categories:

  • Massive party speakers
  • Portable but loud Bluetooth speakers
  • Tiny, impressive speakers

For a little extra help deciding which one best suits your needs, take a look at our guide at the bottom of this page.

Larger speakers for party Hosts/performers

The below speakers make up part of the PartyBox family, loud and powerful JBL speakers designed to be cranked at your next house party or tailgate, or can be used for the busking artist.

1. JBL PartyBox 1000

JBL Partybox 1000

Why we picked it:

The JBL Partybox 1000 is a monster of a Bluetooth speaker. Standing just short of 45 inches tall, the Partybox 1000 and its array of speakers can push some serious volume. The Partybox 1000 also has built-in lighting effects and all the usual party-friendly features and app compatibility. The Partybox 1000 can’t be considered portable though, due to its enormous size and lack of a battery. This speaker is the ultimate house party system.  

Notable Features:

  • Built-in DJ launchpad
  • Microphone & guitar inputs
  • Extensive I/O
  • Onboard lights

Our Thoughts

The JBL Partybox 1000 is an awesome party speaker, especially if you’re an entertainer/musician. While there is no dB rating available for this product, I feel it’s safe to say this is one of the loudest speakers on the market.

Why we picked it:

The Partybox 310 is on the smaller end of the range, a little larger than the smallest Partybox 100 but still easily transportable and not too heavy. The Partybox 310 is one of the largest portable Bluetooth speakers available and sounds amazing, with a bass boost function should you need it.

3. JBL Boombox 2

The Loudest JBL Bluetooth Speakers 2

Why we picked it:

The JBL Boombox 2 is a great speaker for those looking for something large and loud, but not too big that it becomes awkward to carry like the Partybox models can be at times. The Boombox 2 is JBL’s modern twist on the classic boombox style with the addition of some modern features. Aside from the obvious volume and tonal properties, the Boombox 2 is incredibly versatile- use it for your house party, tailgate, home theater, or camping trip. 

  

Notable Features:

  • Loud volume from a medium-sized speaker
  • Incredible bass
  • IPX7 water-resistant

Our Thoughts

I’m not the biggest fan of boombox-style Bluetooth speakers, but the JBL Boombox 2 certainly impresses me every time I listen to it. It’s incredibly user-friendly, sounds amazing, and is one of the most versatile speakers I’ve reviewed.  

8.5

  • It can’t pair with other large JBL speakers

4. JBL Charge 5

The Loudest JBL Bluetooth Speakers 3

Why we picked it:

The JBL Charge 5 is around the shape and size of a football but can reach volume levels that are nearly unmatched by speakers of similar size. The Charge 5 also sounds as good as the larger JBL models, with outstanding low-end and definition. This speaker is simple, easy to use, and sounds great for casual, private listening, small gatherings, and outdoor use.

8
Our Score

Pros

  • Great build quality and design
  • Good battery life
  • Stunning sound quality

Cons

Tiny speakers, big sound

For those looking for ultra-portable, lightweight, and durable speakers to use for outdoor/sporting activities, or even just casual listening without the hassle of lugging around a massive speaker, the below two are for you.

5. JBL Flip 6

The Loudest JBL Bluetooth Speakers 4

Why we picked it:

For speakers this size, not only is the JBL Flip 6 arguably the loudest available, but thanks to JBL’s signature tonal qualities, it sounds amazing across all volumes and, unlike others of similar size and power handling capabilities, doesn’t distort at such playback levels. The soda can-sized speaker is also built incredibly well, with an IP67 water-resistance rating and a shock-proof casing that allows for use in all conditions.  

  

Notable Features:

  • 12-hour battery
  • Classic JBL sound
  • IP67 weather-resistant
  • Reliable build quality

Our Thoughts

The JBL Flip 6 is my favorite small Bluetooth speaker. It doesn’t have any crazy features and isn’t very complicated at all compared to its competitors, but for something portable, reliable, durable, and designed to play music, it does a stunning job. 

9
Our Score

Pros

  • Impressive sound quality
  • Strong sound from a small speaker

Cons

  • A little expensive compared to other similarly-sized and capable speakers

6. JBL Clip 4

The Loudest JBL Bluetooth Speakers 5

Why we picked it:

It doesn’t get more portable than this palm-sized Bluetooth speaker by JBL. We don’t have much to compare this to, but similarly-sized speakers are no match for the JBL Clip’s volume and sound quality. The battery life is incredible for such a small speaker, and the build quality is seriously impressive. This is a great speaker to accompany you on hiking, fishing, or camping trips. 

  

Notable Features:

  • IP67 weather-resistant
  • 10-hour battery life
  • Palm-sized speaker design

Our Thoughts

It’s difficult to compare these kinds of speakers to others that are higher up on this list, but in the market it plays in, it does a fantastic job at delivering great sound, reliable build quality, and battery life while being the loudest in its category. 

9
Our Score

Pros

  • Great sound quality
  • Reliably built
  • Decent battery for its size

Cons

  • Quite expensive for its size
  • No power-bank feature

So which is best for me?

The loudest JBL speakers on this list are noted for being the loudest in their respective sizes and subcategories, though the Bluetooth audio kings have loads more to offer. Finding the best speaker for you will ultimately depend on your intended uses, so we’ve split our selections into a few categories:

I want to host parties

If you enjoy hosting parties or are looking for something to take to your tailgate, or perhaps even something you can use for on-the-go DJ or music performance, the PartyBox range is something for you.

Starting with the loudest, the PartyBox 1000 is one of the most powerful and the loudest JBL speaker on the market, though this comes at a cost- the sheer size of the speaker makes it challenging to transport and isn’t exactly the kind you’ll want to carry around over long distances. If you do have the space (and strength) for the PartyBox 1000, you’ll find its party-friendly and performance features to be quite rewarding, from the DJ launchpad and app compatibility to the variety of inputs available and, of course, the killer sound quality and battery.

If you’re looking for something a little smaller and perhaps more affordable, the PartyBox 310 is an excellent choice. Offering many of the same features as the 1000 model, the PartyBox 310 is loud, durable, and interactive. You can still connect a microphone or instrument, and the onboard battery is quite impressive. Lastly, one that didn’t make the list is the PartyBox 100, which is considerably smaller than the above loudest JBL speakers but is still much bigger than most portable Bluetooth speakers.

I need something loud but portable

If you need a speaker that could go in your backpack or beach bag or even something you don’t mind carrying as long as it isn’t too bulky, JBL has plenty of options to choose from for a variety of uses.

Starting with the biggest, the Boombox and Xtreme models are pretty handy if you’re after something that isn’t awkward to carry but is still on the larger end of the spectrum. In this size range, the Boombox II is our favorite; which is not only one of the loudest JBL speakers but is an incredibly versatile Bluetooth speaker that’s commonly seen on the beach, beside the sports field, or even indoors where it’s used to power house parties, home cinemas, or just casual listening. My only issue with the Boombox II is that the TWS feature isn’t compatible with other larger JBL speakers like the PartyBox models. However, it can still pair with the same of its kind or some smaller units.

On the more portable side of things, the Charge range of JBL speakers is another favorite of ours. They aren’t too big but also aren’t tiny, and the volume these speakers can push is pretty impressive for their size. Their batteries are some of the best in their size category, and they sound just as good as you’d expect a JBL speaker. The Charge models support USB charging of your mobile device and pairing with others of its kind, they can also pair with two Bluetooth sources- perfect for taking turns playing songs with friends. To top it off, they’re pretty durable and can resist water quite well.

What about tiny speakers?

JBL have a few really small speakers that also run circles around their competitors. Starting with the Flip range, which is practically the size of soda cans, they can basically be thought of as a smaller version of the Charge models, except they can’t charge USB-powered devices.

Going even smaller, we have the Clip series, which are about palm-sized, and while they can’t really be compared to the others on this list, they’re included because as far as palm-sized speakers go, they are the loudest and sound the best. Their batteries expectedly aren’t the most powerful, but again, they are still far better than similarly-sized speakers from other brands.

Is the JBL PartyBox 1000 wireless?

No. Due to the intense power usage required to put out the volume it does, the PartyBox 1000 requires a power outlet.

What is JBL PartyBoost?

PartyBoost is the latest technology by JBL for pairing their newer products.

How do I connect multiple JBL speakers?

Step 1. Power on both of the speakers
Step 2. Pair both speakers to your source device (such as your mobile phone), ensuring that both devices appear connected to your device.
Step 3. Once both your JBL Bluetooth speakers are connected, start playing your audio.
Step 4. Once your JBL speaker is playing, press the JBL Connect button (which resembles a triangle infinite symbol) on the speaker playing the audio.
Step 5. Within a few seconds of step 4, press the JBL connect button on your second speaker. The two will sync, and audio will be present from both devices.

Which JBL speakers use Connect?

Connect is the oldest pairing technology from JBL and is supported by Flip 3 and JBL Xtreme.

Which JBL speakers use Connect+?

Connect+ is supported by the Charge 3, Flip 4, Charge 4, Pulse 3, Xtreme 2, and the first generation Boombox.

Which JBL speakers use PartyBoost?

PartyBoost is supported by most newer JBL Bluetooth speakers, including but not limited to the JBL Flip 5, Flip 6, Boombox 2, Charge 5, Pulse 4, and Pulse 5.

Which JBL Bluetooth speakers use TWS?

The PartyBox series utilizes TWS (True Wireless Stereo) pairing instead of PartyBoost. Note that this limits the number of speakers you can connect to only two.

Where can I find the decibel measurements of JBL speakers?

JBL doesn’t publish the decibel readings of their products. One would need to measure it themselves to see exactly how much volume a JBL Bluetooth speaker puts out, which can be a costly exercise.
