So yesterday I let me friend test out my 580's through my ipod (no amp). He listened to 3 dubstep songs, but what I didn't know is that he was listening to them on full volume...
So after that, I put my 580's on and the sound just doesn't sound as good as they did before... The bass isn't as punchy, and the highs are a bit harsh.
Did he damage my can's in that short period of time?
