The Treblab HD77 is designed as a portable Bluetooth speaker with 360 degree sound performance. This speaker delivers a massive 30W (25W RMS) of stereo sound performance and is one of the louder portable Bluetooth speakers we have tested (the JBL Flip 6 speaker also delivers 30W of sound performance). This speaker supports true wireless stereo mode where you can pair it with other HD77 speakers for 60W of stereo sound performance.
While the Treblab HD77 is designed for outdoors, the speaker is only IPX6 waterproof (which means that it can withstand direct splashes of water but cannot be fully immersed in water), and has a similar rubberized exterior and cylindrical shape as the JBL Flip 6. Like the JBL Flip 6 speaker, the Treblab HD77 also comes with two passive bass radiators but uses a less updated Bluetotoh 5.0 version for wireless streaming. It also comes with a built-in battery that delivers up to 20 hours of playtime with USB-C charging.
One aspect of this speaker that differs from the JBL Flip 6 is that it comes with LED light mode to create a party effect while playing music.

Some of the key features of the Treblab HD77 include its durable design with IPX6 water resistance, making it suitable for outdoor activities and capable of withstanding splashes of water. It supports True Wireless Stereo (TWS), allowing for pairing with another HD77 speaker for a much wider listening field. The speaker comes with a built-in rechargeable battery that delivers up to 20 hours of playtime and from our tests around 10 hours at 80% volume level.
We tested the Treblab HD77 speaker against the JBL Flip 6 and we have to say that the Treblab HD77 did deliver relatively good sound performance, although it lacks the highs and deep bass that the JBL Flip 6 speaker can deliver. The Treblab HD77 does deliver pretty loud sound performance and we liked the fact that this speaker delivers crystal clear highs and smooth vocal ranges. The bass output on the HD77 was not as deep as we expected, and you do have to adjust the EQ settings on your iPhone. We played a couple of EDM and hip-hop music genres including Ed Sheeran’s “Shape of You” and JVKE’s “Golden Hour” and they sounded really crisp with nice midranges – the bass is decent but does not deliver the same low end punch that you would get from the JBL Flip 6 or the Bose SoundLink Flex speaker.
Having said that, we did like the fact that the Treblab HD77 speaker does deliver pretty decent highs and crystal clear vocals without much distortion at high volume levels. While the bass is somewhat lacking, you still get decent sound performance from this speaker and it does get pretty loud at 30W power output. We did find that you can also increase the bass response from this speaker by placing it against a corner or the wall.
Compared to other speakers like the JBL Flip 6 or the Bose SoundLink Flex, we would say that the Treblab HD77 does not deliver as much bass or low-end that we would have hoped. This speaker is rather loud and delivers crystal clear highs and vocals, but it lacks bass and sounds somewhat shallow in the midrange compared with the Flip 6 or the SoundLink Flex. It’s overall a nice portable Bluetooth speaker to have for casual listening, but the sound performance does not feel substantially different from any other budget Bluetooth speaker that we have tested.
The Treblab HD77 provides a sleek black exterior with an easy-to-grip grille and impact-resistant plastic cylinders housing passive bass radiators. The HD77 is designed to be rugged and very portable and can be taken anywhere outdoors with its IPX6 water-resistant rating (it can withstand direct splashes but cannot be immersed in water). It features an LED ring on each end that glows blue when on and red when charging or powering down. The speaker has a flat base for stability and includes a pull-away panel for connecting auxiliary or DC 5V cables.
Setting up the HD77 is straightforward and the speaker comes with four rubberized multifunction buttons for power/Bluetooth pairing, play/pause, and volume control. The pairing process is quick and easy, and the speaker supports True Wireless Stereo allowing two HD77 units to be connected for stereo sound. However, it can only connect to one device at a time (such as your smartphone). The effective Bluetooth range is about 33 feet, although this can be affected by obstacles like thick walls.
The speaker offers up to 20 hours of playtime at lower volumes and about 9 hours at full volume. It takes less than 4 hours to achieve a full charge and can play music while charging. Additionally, the HD77 includes a CVC 6.0 microphone for hands-free calls which automatically pausing playback for incoming calls (you can also control the speakerphone using the buttons at the top control panel). This is a slight added advantage over the JBL Flip 6 because the Flip 6 does not come with any built-in microphone.
Overall, the Treblab HD77 is an all-round speaker that delivers decent sound performance with a loud 30W peak power output. This speaker delivers really nice highs, crisp vocals and smooth midranges but is somewhat lacking in bass response as compared to the JBL Flip 6 or the Bose SoundLink Flex. We really liked how portable this speaker is though – it has a sleek design and comes with rubberized buttons on the speaker for easy control to adjust the volume and skip soundtracks. The entire speaker is IPX6 water-resistant and also comes with an LED ring at both ends of the speaker which gives it a nice party vibe. It also has an impressive 20 hour battery life (or 10 hours at 70% volume) and is designed to be portable for outdoor use.
