Plantronics Pulsar 590

Pulsar 590 can do it all. It acts as a pair of wireless headphones for your MP3 player or notebook using a circular Bluetooth transmitter, and it doubles as a hands-free headset for your Bluetooth-enabled cell phone. If you get a call mid-song, switch from music playback to phone mode with the push of a button and extend the nifty telescoping voice tube. With a full battery charge, you can squeeze out 12 hours of talk time.
