Excellent price for a spare or replacement headset for certain Sony Ericsson phones. The headphones are the in-ear kind and sound better than any inexpensive phone trinket should. Although the phone I bought them for is on standby service now, I still have the headphone part (it separates from the mic and proprietary dongle) and use it daily for casual music listening on my mp3 player. When connected to the phone, call quality is good and the mic is reasonably sensitive.
