Sonic Impact i-F2 Speaker w/ Remote-Black
Designed to meet hi-fidelity standards, the i-F2 speakers deliver amazing sound in a wonderfully portable package. That's because they include aluminum cone neodymium drivers for clarity, ported speaker housings and advanced Maxxbass technology that provides an enhanced bass response while minimizing distortion. Along with superior sound reproduction, the i-F2 offers the ease of a durable all-in-one case that keeps the speakers and your iPod safe. It also gives you the convenience of an easy-to-use remote control.
I have one of these and take it with me on every trip. It's great because even if you blast it it doesn't affect the sound quality. I've seen other speakers that look just like this (iHome) and the sound quality suffers.
