Excerpt: I'm "fresh" owner of this headset. This is my first headset of Plantronics, but I'm very satisfied with it. Very good mic sensitivity and clear sound, good sound quality of sound. I use it daily in my work (3-4 hours on head), and I even don't know, that its on my head.
Summary: Picked this up since it is tough to find a new behind-the-head usb headset and the price was nice and low, but I regret the decision. The fit and adjustability leaves a lot to be desired and the volume controls don't work (at least not with the OS).
Pros: USB, behind-the-head design
Cons: Band behind the head is not adjustable, mic location and adjustment is poor, too tight on the ears, volume controls do not work, poor sound quality
Summary: There must be better USB behind the ear headsets...
Pros: Sound is OK if you can get the driver to load
Cons: Painful! If you place your upper ear lobes though the gap between the earmuff and the band, it gets pinched against a sharp edge in the band. If you go over the ear lobe, it is not centered over the ear, nor is it secure. I have a set of Jabra BT phones in this style and ave used them for hundred...
Excerpt: I use this to Skype with my girlfriend, she got an identical one. The answer button on the cord doesn't seem to work but that's kinda pointless anyway. The sound quality is infinitely better than our laptop mics can provide.
