Koss Cobalt Headphones

Bluetooth headphones are no longer a new concept, but we have yet to find a perfectly executed set. A particular sore point is the battery. Quite a few Bluetooth headphones require that you use disposable batteries that add bulk or else continually drain money every few months (if not weeks). That's one area in which Koss' new Cobalt headphones improve substantially. In place of a set of AA batteries, the Cobalt uses a built-in lithium-ion battery: just charge it through a USB cable and you have about 8 hours of use. It can pair with almost anything that supports Bluetooth audio and includes both a USB dongle for computers as well as a minijack transmitter for digital audio players. You can get the Cobalt now for $180.
