TREBLAB HD77 Wireless Speaker with 360° Sound

The TREBLAB HD77 delivers true 360-degree HD surround sound from dual 12.5W drivers and two passive radiators packed into a portable, cylindrical design you can take anywhere. IPX6 waterproofing means pool parties, beach days, and rainstorms are all fair game. With 20 hours of continuous playtime and Bluetooth 5.0, the HD77 is the speaker that keeps the party going long after the sun goes down.

The 360-degree sound architecture projects audio evenly in every direction — no dead spots, no sweet-spot hunting, and no need to aim the speaker at your group. Two passive radiators amplify low-end response, delivering bass that hits harder than you would expect from a speaker that weighs just 620 grams. The 80Hz-16kHz frequency response is tuned for music that sounds full and lively outdoors, where flat speakers lose their impact.

A built-in speakerphone lets you take calls hands-free, and TWS stereo pairing links two HD77 units for a true left-right stereo experience across a larger space. USB-C charging fills the battery in about 4 hours, and four multifunction buttons give you quick control over power, volume, track selection, and calls. The compact 186mm x 78mm cylindrical body fits in a backpack side pocket or a bike bottle cage.

Whether you are hosting a backyard barbecue, camping with friends, or just want room-filling sound in your apartment, the TREBLAB HD77 brings 360-degree audio that punches far above its size. Waterproof, portable, and relentlessly loud.
