No one will suspect that you hold the power to fill an entire room with sound in your pocket. When you pull the podXtreme out for the first time, people might even chuckle. But when they stumble back from the powerful sound this mighty speaker projects, you might just find yourself smiling at their amazement. No other speaker on the market packs such a punch in such a small unit.

So Much Power in Such a Small Space, The podXtreme draws its power from a built-in rechargeable Lithium ion battery that is recharged via your usb port (or you can plug it into the wall). Drawing upon its own power source, the podXtreme allows you to listen to music with much more volume and for a longer period of time than a speaker that pulls power from your MP3 or iPod.
