Nothing Stops the Adventure
Industry-First Floating Playback
While other speakers tip or muffle, Boom 3i auto-corrects to stay upright and keep sound facing forward-even through waves.
Double the Bass
Exclusive BassUp™ 2.0 amplifies every beat, delivering deep 56 Hz bass for a truly powerful listening experience.
5x Saltwater-Resistant
Boom 3i is built for the elements-with a rugged casing and protective coating that defends against seawater, sweat, and salt spray. While typical speakers may rust in under 5 months, Boom 3i stays corrosion-free for up to 2 years of beach, boat, and seaside use.
Versatile Detachable Strap
Clip it, sling it, or grab it and go. The secure,multi-use strap keeps it light and easy-wherever you take it.

Pair two devices to split the channels and enjoy richer, fuller sound all around you.
