OK time for another review - I've had this for over a year as well, and after yesterday, it's worthy of a review.....    For starters I expected the wire to short out months ago, but this headset is going strong, after all the twists and kinks I have put into the cable there's nothing wrong at all, I am very pleased with this headset.
Compatibility-   no worries, I am running it on Windows 8.1!  and in 7.1 surround sound!  
Sound:
This headset packs a PUNCH- it's true 7.1 and I am amazed at the bass and loudness this has-  the microphone is AWESOME and noise cancelling-  I actually use it for voiceovers that I sell (if your interested in needing a voice over- http://fiverr.com/techsaavy  there's samples there too so you can hear that microphone in action )  

Now for the kicker-  yesterday-  there was a trip on the wire (yep another trip on these poor electronic wires)  ( I guess I give things the stress test LOL)  Anyway---- and it got yanked out of my laptop-  needless to say the USB plug was BENT at 90 degrees!  I FREAKED!  Oh no!  I broke it!  It won't work!  Guess what?  I was able to slowly bend it straight and IT WORKS!  I am amazed at the resiliency of this headset!!
