Hum, those look pretty nice! I didn't even know Sennheiser made headsets, to be honest. >.> All the ones I've seen in places like JB/etc around the city have always been headphones, haha.

I would honestly go the other Sennheisers + mic, but I HATE having more than 1 chord around me, soooo I'm not so sure. It's probably something I could get used to, but it's part of the reason I went for the BXR's in the first place. Wireless Hybrid is great. Would like to find another like that, just not..you know, Astros. >.>
Yeah, I had some problems with my Lycosa a while ago, it was one of the batches that had a broken something-or-rather in the keyboard that made the tilde, six, alt, d, and a few other keys not work. Other than that I love my Black Widow Ultimate/Death Adder. I figure the quality would be about the same, I just like to ask, you know. Just to be sure!
