If you damaged the headphone, I would be shocked... I mean it would be SERIOUSLY difficult. It eliminates a lot of back wave distortion, which makes the headphone WAY WAY more detailed, clean, articulate and non-fatiguing. It's THE best mod I've ever tried.
More detailed hm? Doesn't do anything to the frequency response at all, does it? I'd like to keep that amazing response as flat as it normally is.
And that means, with the fuzzor mod, better cables, and the focus pads, I should have a headphone that sounds even better due to all three helping the cans out!
