buzzing sound from KSC75s what did I do?

[afireinside]

This morning I noticed that bass on my KSC75's produces a buzzing sound in the left ear. More so at higher volumes than lower. Did I ruin the driver doing the kramer mods? I bent a bit of the aluminum foil when I popped the grille off to mod it. Odd thing is it seems to go away if I press the headphone to my ear and I haven't noticed it until this morning so could it be something else? Cable maybe? Sorry I'm new to this stuff so I'm pretty clueless

might be hair on the driver- take off the pad and look. maybe spray some compressed air in there.

Yea, mine were buzzing in the left as well after I did the kramer mod.
I removed the driver cover to check if there was any debris in there. My eyees didnt see anything, but I took a can of compressed air and sprayed the driver from a safe distance. I played some music before putting the driver cover back on and the buzzing was gone. Now my Kramer-modded KSC-75's are jumping to a happy tune!

Yep a bit of compressed air and they work fine again

Thanks!

An additional trick that I just never happened to think of when it happened to me is that if by chance you bend the aluminum in the drivers, just take some weak tape and let it stick to the indented part and pull it back up. My KSC75s were bent for the longest time until I was like "duh! tape!"

When my RHS driver got dented, it magically received a slight boost in bass and better treble, so i just left it dented =) Now the right driver sounds better than the left. =D
