Portable Stereo Speaker

The ERKEI SEHN Beat Boom is a battery-powered Bluetooth speaker built for indoor and outdoor listening. Its stereo driver configuration delivers 25W of continuous output with a 50W peak rating. The IPX7 rating means it survives submersion in 3.3 feet of water for 30 minutes. Up to 24 hours of playtime supports extended use away from a power outlet.

Triangular Prism Build

A rounded triangular prism shape makes the unit compact at 2.91 in by 9.05 in by 2.99 in and easy to grip. The rugged chassis resists bumps and drops during transport. A Type-C charging cable is included for recharging the internal battery. Multi-color lights on the surface can be toggled to suit the environment or extend battery runtime.

Bluetooth 5.3 Limits

Bluetooth 5.3 provides a wireless range up to 100 feet from the source device. Pairing two units enables true wireless stereo for wider soundstage and doubled volume.
