Your music. Your sound. Your BOOMSTER.

Whether you're chilling at home with friends, partying in the park or getting into the groove for the next concert - the BOOMSTER is always ready to provide you with powerful sound both indoors and outdoors and is a reliable companion on every adventure.

This sound is yours

The new BOOMSTER has also been rethought acoustically. Of course, this was done to significantly improve the sound, but also to improve flexibility. The certified protection of the sound system against water was only made possible by the implementation of a closed casing, which also brings acoustic advantages.

Robust closed casing offers outdoor protection against water jets according to IPX5 and easily absorbs shocks and impacts.
Class D amplifier for clear sound with sustainable energy management.
Easy to read from every direction, even during the day.
Passive diaphragm for tuned bass.
Midrange driver for best speech intelligibility and warm mids.
Frontfire subwoofer for a precise bass foundation: the bass can be individually adjusted in several stages.
Tweeter for nuanced sound resolution.

Big stereo stage thanks to Dynamore

Thanks to our Dynamore technology developed here in Berlin, the BOOMSTER creates a virtual stereo stage that grows beyond its dimensions. Perfect for MC battles wherever they might take place.

Big FM. Big DAB. Radio with Flow.

The BOOMSTER offers you a wide selection of radio stations. Either digitally via DAB+ or via FM. You can also play internet radio or podcasts from your smartphone via Bluetooth.

On the lips sound

Sound from movies, YouTube or other apps and games is transmitted smoothly and lip-synchronized - without any delay.

Bluetooth aptX

Qualcomm aptX

Bluetooth guarantees a wireless connection with minimal power consumption. Video sound is transmitted in-sync with on-screen images. The aptX codec offers almost CD quality. AptX does not currently work on iOS systems.

Bluetooth Multipoint

Bluetooth True Wireless Stereo

Pair two sound systems via Bluetooth TWS Option with your smartphone, split the stereo channels left and right and experience double powerful sound in stereo.

Ready to play, even in the bathroom

For the first time in the evolution of the BOOMSTER, this new edition offers certified protection against water jets according to the IPX5 standard. Equipped like this, nothing can stop the BOOMSTER from playing - not the bathroom and certainly not rainy days.

Feel the freedom

The way to operate the BOOMSTER has also been updated. The rubberised control panel with its integrated, intuitive buttons, which also provide haptic feedback, is completely new. The unit can also be conveniently controlled from the couch via remote control.

Party all night long

The BOOMSTER comes with a high-capacity lithium-ion battery that can power your party for up to 18 hours (at medium volume), lasting over eight hours longer than its predecessor. A completely empty battery is half-charged in 70 minutes and fully charged in 165 minutes via the mains cable once connected.


Choose your BOOMSTER from two stylish colour options, Night Black and Sand White, or opt for the Kelvyn Colt Edition - only while stocks last.
