If you're talking about some damping or something, yes, GS3 still is capable of driving most of hard headphones because it's got low output impedance. Listening was the first I've done to check it out though.

It won't be able to fully drive it, but listening to low volumes, shouldn't be a problem, like listening to my PFE232's or D2K's
Been doing some more tests.....and I think that min cpu freq has something to do with it.
When moving higher, ie. im at 500 now, the frequency at which the noise comes is reduced.
I'm constantly moving up to see when I won't hear it no more.
I could be wrong, but that's a theory.
At this stage I can't confirm any of what I've found so far, so I'd better return to the very beginning, and then iterate the procedure. One thing I guess is that it might have something to do with the scheduler, not the CPU frequency itself because I checked if the CPU frequency changes significantly if I plug the USB cable into my SGS3, or turn the screen on. No change.
