Plantronics Pulsar 590

Plantronics’ 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. If you’re lucky enough to have an MP3-playing Bluetooth phone that supports the A2DP profile (like the Nokia 8801, reviewed on  http://laptopmag.com/Review/nokia-8801 ), you can stream music from your handset directly to the headphones and leave your MP3 player at home. Playback buttons on the earpiece adjust the volume and skip tracks like any standalone MP3 player. With a full battery charge, you can squeeze out 12 hours of talk time, which is good for a hybrid device.
