I had my pair for about a year and a half, and they were definitely the best purchase I've made headset-wise. They sound amazing, they're wireless, and the mic works wonders. Most reviews will say all of that, so I'll go into my couple complaints.
Once the little fuzzy ball for the mic comes off, which it will at some point, you'll be throwing your couch cushions everyday looking for it, cause it will never stay on. And boy oh boy, the remote is far easier to find that a small gray puff ball.
Additionally, if you get these, make sure you have a surge protector. I don't know how much the transmitter costs, but it was a sad day when my power went out, and everything but my transmitter came back on half an hour later.
Overall, the plusses definitely outweigh the negatives. This is a wonderful headset, and chances are, you won't hear otherwise. Just wanted to give fair warning about the mic/surge protector issues. Get them! They're awesome!
