bluetooth headphones let you listen to music and talk on the phone, wirelessly
Affordable wireless headset that can work with your bluetooth enabled computer and cellphone at the same time. Functions as a remote control for iTunes. Good sound quality and comfort.
Bluetooth headphones are now well established and fairly inexpensive, so even non-early adopters can ditch the wires that tether them to their computer or other sound source. I don't own a pair of wireless headphones yet, but I'm planning on getting some once I've got a home theater PC. Late night gaming/coding/browsing from the comfort of the couch sounds like fun.
