Well I know I wasn't going to get a significant difference, I was just wanting to know if there's any small tweaks or software I could use/get to perhaps improve them, even by the smallest bit.
Yes, I did buy them for xbox originally but I've ended up switching to PC gaming, and I don't have the money to purchase a PC headset.
These aren't that bad, anyway. I don't consider them great compared to most PC headsets, but they're a lot better than ones I've used that are in the ~$100 range.
You can get a cheap desktop mic or a clip-on one (clips to headphone wire) seaparate and a decent pair of headphones/earbuds.
I have Sennheiser CX475 IEM earbuds (caught them at $20 on newegg, $50 now)
They have really nice sound and i don't even EQ my music anymore.
