Too good for the PC
I use them in my hifi most of the time - not the most expensive by far but infinitely better than my PCs onboard sound (yeah maybe I need an upgrade).
Far preferable to so called gaming headphones (a decent desk mic works just as well for voice and you can eat crisps without deafening people!).
ps. Can be had for less than the rainforest store, had mine from overclockers but shop around, a few places stock them now.
