Originally,my point in buying these headphones was to get cheap quality sound.   If I have to spend 20$ on earpads for a 50$ set of earphones, surely I could just get a better over-ear headphones for the 70$ total I was about to spend?

Hey,   I'm about to buy a new gaming PC, and for the sound I'll use the HA-S500-Z headphones.   As I understand it, there's a way to mod them so they'll be more comfortable by replacing the earpads with over-ear pads. The thing is, I'm pretty much a noob as far as headphones are concerned...
