Pros

- Bluetooth and AUX input let you switch between wireless and wired sources.

Read the full review summary
The HD77 is worth considering if you want one speaker for a patio, campsite, or trip where splash and rain protection matter.
It combines Bluetooth and AUX playback, a built-in microphone for hands-free calls, and lights that can be switched off to preserve battery life.
Its mix of portable design and flexible connections should appeal to casual outdoor listeners who value simple setup and visual atmosphere.
The main tradeoffs are that the lighting draws on a battery-powered design and stereo pairing requires a second HD77; consider how often you will use those features before choosing it.

Who Should Buy TREBLAB HD77?
Good fit
Choose the HD77 if you want a portable speaker for backyard listening, trips, or casual gatherings and value a water-resistant design.
Its lightweight build is intended to fit in a backpack, while IPX7 protection covers poolside use, beach trips, and light rain exposure.
It also fits buyers who want both Bluetooth and AUX playback, or a speaker that can handle hands-free calls.
RGB lighting adds some atmosphere, and turning it off offers a simple way to conserve battery when the light show is not needed.
Who should skip it
Skip it if you need left-right stereo from one speaker alone: TWS stereo is designed around pairing two HD77 units.
Also look elsewhere if your priority is calls in windy outdoor settings, and check microphone performance before relying on it for that use.
TREBLAB HD77 Review: Outdoor Listening, Lighting, and Pairing
A flexible speaker for day trips
The combination of a lightweight body, Bluetooth, and AUX gives the HD77 useful flexibility for travel and outdoor listening.
The stated wireless range is up to 100 ft (30 m), which can help when the playback device is nearby but not directly beside the speaker; actual connection conditions can vary by setting.
Water protection for outdoor plans
IPX7 protection gives the HD77 a defined water-resistance use case for poolside listening, beach trips, and light rain.
The submersion rating adds context for accidental exposure, though this is still best treated as a portable audio speaker rather than a reason to take it swimming.
Lighting and battery choices
Music-synchronized RGB lighting makes the HD77 more visually expressive for a patio or gathering, and the ability to turn the lights off gives you control over that feature.
USB-C charging supports up to 20 hours of playback, but treat that as a maximum rather than a guaranteed session length, especially when the lights stay on.
Stereo requires a second unit
The HD77 can form true wireless left-right stereo through TWS pairing, which gives you a path to broaden a setup if you later add another matching speaker.
Buyers who want stereo should account for that second unit as part of the plan; this model’s one-speaker listing does not make the pairing feature a built-in two-speaker arrangement.
