Customer Review: lasted 1 week.
I'm fairly particular when it comes to call quality, and this headset does not provide any call quality. People couldn't hear me, the background noise was unbearable to people I called. Then, after a week, the unit fell apart -- plug broke, clip broke. Skip this one.
