Hi guys, happy holidays! I was lucky enough to get a pair of sennheiser pc 350's from santa to replace my Zalman Theatre 5.1's and am I'm quite dissapointed in the sennheisers so far. Am I doing something wrong here? I have them hooked up to my trusty xfi xtreme music which my Zalmans just sounded incredible on IMHO. But these senns sound like 30 dollar headphones??? and they werent 30 bucks! I get that I have lost the surround sound but I just dont feel the "atmosphere" in the games that I play, kinda feel like im in a box running around. I'm sure I'm doing something wrong as these heaphones have gotten decent reviews. Is it just a case of the new sound and my ears not used to it?
