I'm looking for some headphones with a little bit of complex criteria. I'd like either true 5.1 or simulated. For the most part they'll be used for my computer at night. Right now I plug my headphones through my center speaker with 1 cable. I don;t really want to be switching it with my speakers each time at the sound card. I've seen some with built in sound card or a device that connects to the headphones. but on the connecting end i would like 1 2.5mm connector. Suggestions? edit: post thoughts on the subject as well. am i losing potential quality by plugging into my center speaker with 1 cable. even if the speakers come with a device?
