Big Sound, Built for the Outdoors

The kyenook BOOMBOX4 is made for the moments that need volume: campfires, pool days, backyard parties, and road trips. 60W of rated power (120W peak) pushes deep, room-filling bass through dual bass radiators — the kind of low end you feel in your chest.

Bass You Can See

Hit bass boost and the side radiators come alive with a breathing LED glow that pulses with your music. It's not just a speaker — it's the centerpiece of the party.

Double It Up

Pair two BOOMBOX4 speakers wirelessly for true stereo separation. One on each side of the yard and you've got a sound system, not just a speaker.

Every Source Covered

Stream over Bluetooth from your phone, plug in a USB drive or TF card, wire up with the 3.5mm AUX, or tune into FM radio. Whatever you have, it plays.

Ready for Real Life

A splash-resistant build with sealed port covers shrugs off poolside splashes and sudden rain. The integrated handle and 4000mAh battery mean the music goes wherever you do.
