Read the full review summary
The HD77 combines dual full-range drivers with 30W output and 360° stereo sound, then adds RGB lights that pulse with music.
Its AUX input also gives buyers a way to connect a non-Bluetooth audio source, making it a flexible option for backyard listening, camping, and other trips where a compact portable speaker is useful.
It is a good fit for buyers who value a long stated playback window, USB-C charging, and IPX7 water protection.
The lighting can be switched off to preserve battery life, and the built-in microphone supports hands-free calls; for frequent outdoor calling, check whether microphone performance suits your setting before buying.
The buying factors
HD77 Speaker Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Portable audio feature set
The 30W configuration uses dual full-range drivers and 360° stereo sound, a useful combination for shared listening in varied outdoor spots.
Water protection
IPX7 protection is rated for submersion up to 3 ft (1 m) for 30 minutes, which supports poolside or rainy-day use; it should not be treated as a swimming speaker.
Playback flexibility
Bluetooth and AUX input support wireless or wired listening, and TWS pairing lets you pair two HD77 speakers for left-right stereo sound.
Lighting options
Music-synced RGB lights add a visual feature, while the option to turn them off gives buyers control over that effect and its battery use.
Battery convenience
USB-C charging and up to 20 hours of continuous playback suit longer outings, although the maximum is conditional on use and the lights affect battery life.
Carry and call features
The lightweight design is intended to fit in a backpack, and a built-in microphone supports hands-free calls, adding useful travel flexibility.

Who Should Buy HD77 Speaker?
Good fit
Buy the HD77 if you want a portable speaker with 360° stereo sound, IPX7 water protection, and RGB lighting that reacts to music. Its backpack-friendly design and USB-C charging suit buyers planning day trips, camping, or backyard use.
It also fits listeners who need an AUX connection for older or non-Bluetooth sources, or who may want to pair two HD77 speakers for left-right stereo.
The lights can be turned off when their visual effect is not wanted.
Who should skip it
Skip it if you need a speaker for swimming or submerged listening. The IPX7 rating covers specified submersion conditions, but the product is framed for poolside and outdoor use rather than underwater playback.
Look elsewhere if you need dust protection as a stated part of the rating or depend on clear microphone pickup in windy outdoor settings; evaluate those needs before choosing this speaker.
HD77 Speaker Review Analysis
Sound setup for shared listening
The dual full-range drivers and 360° stereo positioning point toward listening around a group rather than keeping sound aimed at one person.
TWS pairing can expand the setup to left-right stereo when you have a second HD77, though that requires buying another speaker.
Water protection and outdoor use
IPX7 protection is useful around a pool or during light rain, with the stated submersion rating giving a defined limit.
It does not establish dust protection, so beach and campsite users should keep sand and grit in mind when choosing where to place it.
Battery and lighting choices
The up-to 20-hour playback window suits outings where charging access may be limited, while the RGB show can be turned off independently to preserve battery life.
Treat the maximum as a planning guide, especially if you intend to use the lighting throughout a session.
Connection options for travel
Bluetooth supports wireless playback, AUX input connects a wired source, and the built-in microphone supports hands-free calls.
Buyers who mainly need the speaker for calls should consider whether its microphone will suit their usual environment, particularly outdoors where wind can complicate pickup.

Read Amazon ReviewsTeufel Fender x ROCKSTER GO 2
Choose the ROCKSTER GO 2 if you prioritize dust protection, attachment options, and a longer stated battery window. Choose the HD77 if RGB lighting and AUX input matter more for your listening setup.
- The ROCKSTER GO 2 is an ultra-portable speaker with an IP67 dust- and waterproof design, a flexible strap for bike or backpack attachment, and up to 28 hours of battery life.
- The HD77 offers music-synced RGB lighting, an AUX input, and up to 20 hours of playback, with IPX7 water protection.
Is HD77 Speaker Worth It?
The TREBLAB HD77 is worth considering if you want a portable speaker with 360° stereo sound, IPX7 water protection, music-synced lights, and both Bluetooth and AUX playback.
Its backpack-friendly design and USB-C charging also suit travel and outdoor listening.
Its clearest compromises are that the 20-hour figure is a maximum affected by lighting use, and the water rating does not include a dust rating.
If those tradeoffs match your plans, the HD77 offers a useful mix of portability, connection choices, and outdoor-oriented features.
