Eton Rugged Rukus Xtreme The Super-Loud, All-Terrain, Smartphone Charging, Dual-Powered Wireless Sound System for Xtreme Audiophiles, NRKS400GR

We're talking huge, crystal clear audio with stereo sound. Featuring digital signal processing (DSP), two full range speakers and bass extending passive radiators for that low-end boom. Take it with you on your adventures, the sunshine will power the rukus to keep your tunes playing. If your phone starts to die, no worries, plug it into the rukus to get a charge. When it gets dark, the internal lithium battery will keep the music going for hours or you can use the included AC adapter for non-stop songs. Stream all your music from almost any Bluetooth-enabled smartphone, tablet or computer. Plus advanced Bluetooth 4.0 with AVRCP to control your tunes from your device. And for non-Bluetooth devices, there's an aux-in. Audiophiles, it's time to make a real rukus.
