It is a dustproof, splash-resistant, mobile Hi-Fi system. Thanks to the professional battery, it has a very long playtime. In stereo and with the most exclusive speakers. It feels most at home outdoors in the workshop, in the countryside, on the boat, at barbecues, and while traveling (sometimes even for weeks during private use). It is dustproof and splash-resistant (IP65) and 100% washable, making hygiene easier. It is unaffected by bumps, falls, dust, and sand.
