The speaker is powered by USB but takes audio over a normal headphone jack, so you don’t have to carry a power adapter for it or install drivers to use it. The rechargeable internal battery provides more than 7 hours of playback time when using it with iPods or portable CD players that don’t have a USB port. The device recharges whenever it is connected to a USB port, and can be charged from a USB wall adapter (like the one that comes with iPods) or USB cigarette lighter adapter (like the one that comes with iPod car kits).
The Sound is quite loud—it will definitely fill a small room—and the dynamic response is fairly good. Bass response is excellent considering the size of the device. Bass response is quite warm and not at all “brassy” like most small speakers. Distortion is apparent in the top 10% of the volume range, but that’s likely louder that you’d want anyway.
The speaker is tiny and will fit in any laptop bag with no problem—it actually takes less room than most headphones. It opens easily to expand its bass reverberation chamber, which is the secret to the bass response. You can clearly hear the difference in the warmth and volume of the sound when the speaker is opened versus closed.
