I have read Mad's huge thread on headphones and gaming. It seems I have come down between the Q701 or the PC350. I play only on PC and will also be adding in a Asus Xonar Essence Stx sound card. From what I have read these come with a built in amp that should be good to power the Q701. As for the PC350 I am sure this will be a great addition to powering them as well. Now my current headset is the Razer Kraken 7.1 with no sound card. They don't use your sound card anyways. To me this headset seems kind of muddy in the sound. I am 90% sure these headphones I have listed are much much better than these Razers. The Razers are closed ear. I used to have Razer HP-1 which I think were open ear. I could hear external sounds. With these new Razers I cannot. I def like that, but it is not a deal breaker hence why I have both closed and open ear listed. I know that if I go with the Q701 I would have to buy an add-on mic which is ok by me. One other question I have is would I need to buy anything else besides the sound card and the headset to make it perform great? I do 90% gaming, 5% movies, and 5% music. So those latter ones don't need to be top notch. I am more focused on positioning.
Thanks for taking your time and reading.
