So i got some cheap sony headphones. The sound quality is great for the price but there's a slight problem. I don't know why but the ear cups are built in a way that create the same sound you get when you cover your ears using your hands, or a cup. I don't know how to describe it and it surely isn't a software problem, since it happens even when they're not plugged in. I'd say i have normal ears. I've never had this weird problem with other cheap headphones. I can probably get used to it but still it's pretty annoying and it's not that noticeable when there's sound coming out of the headphones.
