As our MP3 players get smaller and more robust every year, it seems reasonable to expect the same from our portable speakers. The X-Mini MAX II Capsule Speakers, like your iPod, fit in the palm of your hand and deliver exception sound. These ultraportable pods deliver booming bass through XMI’s innovative technology that uses an accordion bass expansion system that replicates the resonance of a sub-woofer. When you’re not listening to music the two speakers clip together by magnetic bases and stay compact in your bag. With a full charge X-Mini Max II Speakers can pump out music for up to 10 hours, getting you through a day or work or a night of fun.
