Portable speakers often compromise between loudness, battery life, and durability, but the TREBLAB HD77 is designed to balance all three. Its cylindrical build delivers sound evenly in all directions, making it well-suited for group settings like outdoor gatherings, poolside use, or campsites where listeners aren’t positioned directly in front of the speaker.
Audio output is punchy for its size. Dual drivers paired with passive bass radiators help produce fuller low-end response than typical compact speakers, while still keeping vocals and mids clear. The volume level is sufficient for outdoor environments without needing to max out the speaker, which also helps preserve sound quality.
Battery performance is another practical strength. With up to 20 hours of playtime, the HD77 can handle a full day of use on a single charge. The built-in strap makes it easy to carry or attach to a backpack, bike, or gear setup, reinforcing its portability focus.
Durability is clearly part of the design. The waterproof and shock-resistant build allows it to be used around water, sand, and unpredictable weather without much concern. The added TWS stereo pairing option gives users the ability to link two speakers for wider sound coverage when needed. Overall, the HD77 is best suited for active users who want dependable sound in outdoor or travel-heavy situations rather than a speaker meant only for indoor listening.
