Treblab HD77 Bluetooth Speaker Review

-

The Bottom Line

Despite playing in a competitive space in the market, the HD77 from Treblab is able to go toe-to-toe with bigger brands in performance, even at its affordable price point. Compared to the HD7, the younger brother of the HD77 – you’re going to be getting a whole lot more volume, wider response range in the bass frequencies as well as both shorter charging time and longer battery life. Overall it’s tough not to recommend the HD77 as an affordable portable Bluetooth speaker.

Our next adventure into Treblab’s range of Bluetooth speakers takes us through the HD77- the middle sibling between the soda can-sized HD7 and the mighty HD Max. The HD77 shares many features with the rest of Treblab’s series of Bluetooth speakers, let’s take a look:

Durable Build and Design

The Treblab HD77, as mentioned is the middle-sized model in the HD range of Bluetooth speakers. The HD77 is comparable in size to a 16-ounce soda can, so it is still relatively portable in comparison. To aid its portability, the Treblab HD77 comes with a carry strap with a carabiner to allow for it to be attached to your backpack or belt or simply sling the strap over your shoulder. 

An IPX6 weather-resistance rating means the Treblab HD77 can practically be taken anywhere with you, as long as it doesn’t end up underwater. It can withstand splashes from all directions of varying pressures, as well as resting gently on the sand or snow. In addition to this, the HD77’s enclosure is fully shock-proof and can also survive a gentle drop from hand height to the ground. 

Easy Setup and Pairing

As with the rest of the HD range of Bluetooth speakers, Treblab has made an incredibly easy-to-use speaker. I managed to set up this device within seconds, and both devices remember each other to allow for automatic pairing every time the speaker is turned on (provided your Bluetooth is always activated on your source device)

My only complaint so far would be the fact that only one device can be connected at any one time, which can be a slight annoyance if you want to bounce between songs with friends. 

The range of the Treblab HD77 is standard here, allowing for a distance between devices of up to 33 feet while the connection remains strong and powerful across this range before the signal suffers, especially outdoors. 

The HD77 is also capable of True Wireless Stereo (TWS) pairing, allowing you to connect two Treblab units to form a stereo pair. This will certainly improve the stereo spread if you plan on using the Treblab HD77 for film viewing or critical listening, and the inherent volume boost is great for party-like environments. 

As for controlling the speaker, the onboard buttons on top of the unit are easy to understand and use. The buttons provide control of the basic features (power on/off, play/pause, volume up/down, etc.) as well as some phone call-related features which we’ll get into later.

Impressive Sound Quality

Treblab is known to draw attention to sound quality and ease of use rather than lights and other gimmicks when it comes to their Bluetooth speakers. They consistently produce great-sounding equipment and the Treblab HD77 is yet another model that proves this correct. 

The HD77’s frequency response only begins at 80Hz, which has quite an impact on the low-end response of the speaker. While the Treblab HD77 may not be able to produce the bone-shaking bass you might be after in bass-heavy music, it provides just what you’d expect from a speaker of this size and does not disappoint. It goes without saying that in comparison to the smaller HD7, the HD77 can output a slightly more powerful bass response. If you’re looking for a Treblab speaker with the same features but greater bass response- take a look at the HD Max. 

The midrange of the Treblab HD77 is tight, warm, and clear: great for guitar-based and singer-songwriter music. This is definitely where the HD77 shines sound-wise and the warm lower midrange body makes up for the lost depth in bass response. As for the high-end, one can expect bright and crisp tones here. While the Treblab HD77 does not explore the entire upper range of human hearing either, a threshold of 16Hz is enough for most uses, it is a portable Bluetooth speaker after all and not designed for critical listening. 

Volume-wise, the HD77 is capable of reaching fairly loud volumes, though not to the degree of some of the larger, louder Bluetooth speakers on the market. While you may experience slight distortions and pops at high levels, you really have to push the speaker to that point in order to hear this. For casual at-home listening or for carrying around hiking, camping, fishing, or at the beach, the Treblab HD77 provides enough volume for personal background music or to provide some ambiance when relaxing with a small group but aren’t necessarily looking for a pumping party (if you’re looking for a party speaker check out our selection of party speakers here instead).

Great Battery Life

Treblab is great when it comes to the battery life of their devices. The Treblab HD77 can run for a total of 20 hours straight when played at a lower to medium volume level, and 9 continuous hours at full volume. The battery life can be further extended by using the 3.5mm auxiliary connection rather than Bluetooth.

The HD77 obtains a full charge in just 4 hours or less, and it can still play music while it is on charge. The only downside here is that the HD77 does not notify you incrementally as the battery life weakens, and only lets you know about low power once it is practically about to die, so be sure to keep track of the battery life and charge the speaker fully before taking it out with you.

Additional Features

Treblab is really good at building decent-quality microphones to incorporate into their speakers. In the case of the Treblab HD77, a CVC 6.0 microphone is included, providing hands-free use while the speaker is connected to your phone or laptop. The HD77 will automatically pause playback when an incoming phone call or Skype/Zoom request is detected, and you can accept, reject or hang up using the buttons of the speaker. Once the call has ended, the HD77 automatically resumes playback. The microphone sounds good enough for a Bluetooth speaker, there are certainly worse-sounding mics out there. 

Liked

  • Compact design with modern features
  • Good sound quality for a great price
  • Water-resistant and durable build

Disliked

  • No ‘low battery’ notice period
  • Only one device can be paired to the HD77 at once

Final Thoughts

The HD77 is another great, compact, and powerful Bluetooth speaker from Treblab. They really did a great job in covering a nice range of products in the HD series, where you have everything from pocket-sized to boombox-comparable designs, and the HD77 is a perfect fit right in-between. The HD77 has all the basic features you could want in a portable Bluetooth speaker and sounds great for its size and price point.
