Pros: Fantastic sound quality, from the speakers and the microphone alike. Definitely the best quality sound I've ever heard from any headphones. The little USB soundcard is fairly good too. This headset would easily get 5/5 eggs, if it wasn't for the huge con...

Cons: As I type, I'm wearing my fourth pair of this headset. Between 3 months, to 1 year, they break, and in exactly the same place. I figured through each purchase they might have updated the design to fix this, but they haven't. The warranty expires after 30 days, and sending them to the factory for repairs costs just as much as buying a new pair does. This is ridiculous, and why I won't be buying a fifth pair.

Overall Review: Seriously, there's big forum threads about this exact problem, and Plantronics does nothing. Terrible support for their products. If you want your headset to last for more than a year, get a different one. Otherwise, they're fantastic.

Pros: Worked fantastically while it wasn't broken.

Cons: The one I got had a faulty ATX connector on it, so it would occasionally become disconnected and my PC would just shut off, and then I'd have to push on the cable a bunch to get it to make a connection again. I let it do that for about a week before I got fed up and RMA'd it. I get that it's refurbished, but I'd at least expect it to work properly. This just feels like they took someone else's faulty return, put it in a new box, and sent it to me instead.
