iMainGo X

is a 6-by-4-by-2.5-inch protective case for an iPod, iPhone, or most MP3 players that incorporates stereo speakers into its housing. The stereo sound is loud and clear, the bass big and full.

The 3.5mm plug can be plugged into any device with a 3.5mm connec-

tion, or you can use a 2.5mm adapter. Push the case's power button, and you've got sound.

The speaker/case is coolest when used with a small device that slides into the transparent sleeve, letting you carry and play the device without opening the case.

In addition to external speakers, the case has dual headphone jacks and a microphone input (for karaoke nights, of course). The speakers run on a rechargeable lithium ion battery that's included, as are an AC charger, a carry bag, and wrist and shoulder straps. iMainGo X (10BWS03) costs $69.95 at
