Currently using two mouse pads I picked up for free at random events, a Logitech g502 mouse, a CM keyboard, and SHP9500 headphones!
I want new headphones :(. The SHP9500s had great reviews, but it slides off my head if I move too much, and the inside of the earcup rubs on my ear so I can't wear them for too long before my ear tips get sore.
