Read the full review summary
The HD77 pairs 30W output with dual full-range drivers and 360° stereo positioning, giving it a feature set aimed at shared listening rather than private desk use.
Its IPX7 rating and portable design make it a sensible candidate for poolside or backyard use, provided you respect the stated submersion limit.
It is especially appealing if you want lighting as part of the setup, but appreciate being able to switch that feature off to preserve battery.
Bluetooth 5.0, AUX input, a built-in microphone, and up to 20 hours of playback cover several common use cases without making the HD77 a specialist speaker for any one of them.
The buying factors
TREBLAB HD77 Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Outdoor water protection
The IPX7 rating supports poolside and light-rain use, with a stated submersion limit that calls for sensible handling around water.
Playback duration
Up to 20 hours makes the HD77 suitable for a long day out, while actual runtime can vary with use, including whether the lights are on.
Connection flexibility
Bluetooth 5.0 and an AUX-in port let buyers choose wireless playback or connect a non-Bluetooth source.
Stereo expansion
TWS pairing allows two HD77 speakers to create left-right stereo, which can suit a larger gathering better than relying on one unit.
Lighting flexibility
Music-synchronized RGB gives the speaker a more playful presence, and independent shutoff helps when lighting is not wanted or battery conservation matters.
Call and wired-use options
The AUX connection and built-in microphone broaden its everyday uses, though buyers making frequent outdoor calls should check whether the microphone suits their conditions.

Pros and Cons of TREBLAB HD77
Pros
- IPX7 water protection suits poolside settings and light rain when used within its submersion rating.
- Up to 20 hours of playback suits extended outings, with USB-C charging.
- RGB lighting adds atmosphere and can be turned off independently to conserve battery.
- Bluetooth and AUX provide wireless and wired source options.

Who Should Buy TREBLAB HD77?
Good fit
Buy the HD77 if you want a portable speaker for backyard listening, camping, or poolside use and value IPX7 protection alongside Bluetooth and AUX playback.
Its submersion rating is bounded, so treat it as water protection for appropriate outdoor use rather than a reason to use it without care around water.
It is also a good fit when synchronized lighting is part of the appeal, or when two matching speakers for TWS stereo is a useful future option.
For longer sessions, the up-to 20-hour figure is a helpful planning point, not a guarantee for every listening setup.
Who should skip it
Skip it if you need explicitly dust-rated protection or a speaker whose suitability for your specific outdoor call conditions is already established.
The HD77's IPX7 rating is water-focused, and a built-in microphone alone is not a reason to assume clear calls in wind.
TREBLAB HD77 Review: Outdoor Audio and Everyday Tradeoffs
Water protection for outdoor use
IPX7 waterproofing suits poolside listening and light rain, with submersion rated up to 3 ft (1 m) for 30 minutes.
It can help protect the speaker from splashes, but water protection should not be confused with dust protection or unrestricted use underwater.
Battery and lighting choices
Up to 20 hours of playback is useful for outings where charging access is limited.
RGB effects bring visible energy to a gathering, and their independent shutoff gives buyers a way to prioritize runtime when the light show is unnecessary.
Connections for varied sources
Bluetooth 5.0 covers wireless listening, while the AUX-in port accommodates a non-Bluetooth audio source. TWS adds a further path to left-right stereo using a second HD77, although that option depends on buying and placing another matching speaker.

Is TREBLAB HD77 Worth It?
The TREBLAB HD77 is worth considering if you want a portable outdoor speaker with IPX7 water protection, up to 20 hours of playback, RGB lighting, and both Bluetooth and AUX input.
Its strongest case is versatility for casual shared listening, with the option to pair a second unit for TWS stereo.
Buy it if those features match your outings and you are comfortable with water-focused protection rather than explicitly dust-rated coverage.
Be realistic about battery expectations when the lights are active, and check microphone performance before depending on outdoor hands-free calls.
