So I bought this new headset about two weeks ago (The sennheiser PC 333D 7.1 surround sound one) and about two days ago the bass in the left earcup is not as much there as it is on the right one, it also makes a slight scratching sound when there's a song/movie that has a part where there's alot of bass

Is this my laptop's problem or is this headset already broken?
