Disclaimer: I've never tried surround sound headphones, so this is more that I quite like the idea of them - so if there is a better option them I'm all ears (excusing the pun). Simply put, I just want some decent headphones that will help immerse me in my gaming (hence the perhaps misguided notion that surround sound is the way to go). Good for music too. Up until this point I've just used some cheap £15 JVC headphones (which actually sound decent to my poor ears), so I don't need high-end enthusiast stuff, just something that offers a good price/performance combo. What should I be looking at?
