Query: Those in Dorms! - BEWARE

I live in a college dormitory and purchased these for listen to music + didn't want to get a wired one to chain me to my computer. Huge mistake. Whether it's due to the wireless internet floating around or causes unknown, the sound was awful. Hissing, popping,and a fuzz that made listening to anything impossible. Avoid these headphones!!! Mine are in the process of return right now.
