Eton’s solar speakers are pretty decent for folks who spend a lot of time outdoors. The Eton Rugged Rukus Xtreme happens to be a rugged, splashproof speaker system with solar charging and NFC technology on-board. This device works with your Bluetooth and non-Bluetooth devices. It features digital signal processing (DSP), two full range speakers and bass extending passive radiators. You can stream music from your smartphone, tablet, or computer. The device will be available early July.
