I've been using the Steelseries Syberia v2 USB headset (with soundcard) for over a year, and they definitely set a high bar when it comes to audio/PC gaming sound. In my opinion, they're amazing, and one of the best pairs of headphones/headset ever made. There's a single cable, not too long, the headset is comfortable, the sound is amazing (especially the bass), and I'm currently looking for a replacement for those. If I can't find one by then, I'll simply buy another pair.
I've checked, I think, every pair of headset available on the internet. I don't care if they're cheap, expensive, heavy, lightweight, I am currently in need of a new pair. Something I don't want: too many wires. Since my computer isn't far away like my Xbox is, I'd like 2 different wires at most. If they can be sleeved together it's fine also (if there's a few). Also, if it's wireless, it has to have an option where I can plug it in when I need the power (ex: Logitech G930).
Example of headsets I checked and didn't like due to to factors I listed; Astro A40 (even thought they sound awesome, WAYYY too many cables), Tritton headsets (if I recall, they aren't very expensive for PC so I wouldn't expect anything really exceptional out of it. Highest PC one is 95$ @ Newegg.)
Note: Some headsets are for PC/Xbox/PS3, so even thought they look nice for all consoles, they aren't optimized for the PC, so sometimes they don't have drivers or software. My current headset (Syberia v2) has a software, and I can tweak what I like (equalizer, amplifier, 7.1, bass, etc).
TL;DR - Any ideas? I'm also open to headphones + mic. Yes, the recommended headset can be VERY expensive, I don't have a set budget for those. I just need quality.
EDIT: Any comments on the Psyko 5.1 headset? It looks sick, new design if I recall.
