Beware of Punk from Sol Republic. Smaller, tougher and louder than you would expect, the Punk Portable Bluetooth Wireless Speaker is the ultimate sidekick to make your music heard. Surprisingly loud for its size, Punk is fearless. Crank up the volume and fill your room with music or take the party outside. Water resistant, Punk can lounge poolside. Shock resistant, Punk is not afraid of ruthless backpacks. Even dust doesn"t bother Punk, so mount it to your bike using the 1/4-inch threaded mount and head up to the mountains. Punk goes with you anywhere, all day with long-lasting 8-hour battery life. Super social, Punk lets you connect any non-Bluetooth audio devices using the 3.5mm cable. You can even connect to that old stereo using Punk as a Bluetooth hub. If you won"t break the rules, Punk will.
