Read the full review summary
The HD77 brings together portable Bluetooth playback, an AUX input for wired sources, and TWS pairing for a two-speaker left-right stereo setup.

Who Should Buy TREBLAB HD77?
Good fit
Choose the HD77 if you want a portable speaker for outdoor listening, and IPX7 protection is important for poolside use, beach trips, or light rain.
Its compact design is intended to fit in a backpack for travel, hiking, and day trips.
It also fits buyers who want a choice between Bluetooth and wired audio, or who may later pair two HD77 speakers for left-right stereo.
The RGB lighting adds a music-synchronized visual feature that can be switched off when desired.
Consider it for extended day use if up to 20 hours suits your routine, with the understanding that this is a maximum rather than a guarantee for every lighting and listening setup.
Who should skip it
Skip the HD77 if your priority is left-right stereo from one speaker: its TWS pairing creates that stereo effect only when you pair two HD77 speakers, so it may not fit a setup that needs sound from a single unit.
Also look elsewhere if you need a speaker specifically intended for underwater playback; the IPX7 rating describes submersion protection, not a use mode for listening underwater.
TREBLAB HD77 Review Analysis
Outdoor water protection
IPX7 certification makes the HD77 relevant for buyers who expect splashes, light rain, or poolside and beach use.
It is described as rated for submersion up to 3 ft (1 m) for 30 minutes, but that protection does not make underwater listening its intended role.
Battery and lighting choices
The USB-C charge supports up to 20 hours of playback, with the actual result dependent on use.
The RGB lights can be turned off independently to preserve battery life, giving buyers a straightforward way to prioritize lighting or runtime.
Flexible playback and placement
Bluetooth 5.0 is the wireless route, while the AUX input accommodates a non-Bluetooth source.
TWS pairing is useful when a two-speaker left-right arrangement is preferred; buyers planning to use it in a larger space should consider whether that setup is worthwhile for them.
