I have this headset already bought about 6 times. The voice quality and usability and comfort are good. Unfortunately, not processing. It survived about 4 months with daily use, then it falls apart inevitably. There are no real alternatives. The Panasonic is high as bad. Use Amazon's guarantee! I think it's nice of Plantronics, that they produce the thing, but I'd like to spend twice and get a life that makes sense almost.
