The BOOMSTER GO puts the legendary Teufel sound in your hands. Whether hiking, biking, or orbiting Mars, where will you take it? This robust Bluetooth speaker comes in five stylish color variants and delivers powerful sound for any occasion. Waterproof according to IPX7 standards, its rubberized housing protects against impacts, featuring a high-performance full-range driver and two passive bass drivers in a push-pull configuration for tight, high levels without distortion. A clever strap and a GoPro-compatible thread (¼ inch) allow you to attach the BOOMSTER GO to just about anything: bike, belt, tripod, backpack, or even a space capsule. Bluetooth enables music streaming from Spotify, YouTube, Apple Music, TuneIn, and more. Additionally, two BOOMSTER GOs can be paired to play synchronously in stereo. It has a high-capacity battery for playtimes of up to 10 hours, quick charging times with control buttons on the device, an LED battery indicator, and a hands-free function.
