I've had a pair of Beyerdynamic DT 770 Pros for a while now, and ever since I can remember, in the left ear, there has been a slight buzz/rattle noise. Almost cringle-y. This only happens on bass-heavy songs, or when audio is noticeably compressed (like youtube videos). I normally don't listen to music at full volume, but if I go past 60% volume, I can notice it. It's gotten worse over time. I have tried looking for a hair in my driver so many times, and completely scanned it for a hair and I have never found one to cause the problem. I highly doubt it's a hair, and if it is, there's no way it'll come out.
Do you think my driver might be busted or something? I'm not exactly too great with things like this, so I'm not sure if maybe I'd need an amp (I know nothing about this), or if maybe the driver is broken. I bought them second-hand (bad idea). What could be my problem, and how could I fix it? If there's no way to, I'll be in the market for new headphones.
I'm using it with my computer, and that's it. It's a creative sound card: Newegg.com - Creative Sound Blaster X-Fi Xtreme Audio 7.1 Channels 24-bit 96KHz PCI Interface Sound Card - Sound Cards
