So I just picked up a Sennheiser HD-650, and coming from a pair of cheap $10 Sony headphones, I'm, of course, picking up greater clarity and detail in the treble areas of songs and recordings, particularly from percussion instruments.
But in some songs/recordings, there is, what it seems, some distortion, or very, very slight buzzing or shimmering in percussion instruments.
It's been so long that I've used these cheap Sony headphones, which emphasize mids and bass way too much, that I have no idea if those buzzing or shimmering sounds are supposed to be there.
Of course, since these are percussive instruments, one would expect there to be some of those buzzing/shimmer qualities, but I just want to make sure.
And of course, it could just be the recording and/or the source (either the sound file or the soundcard) just being bad.
So how do I know if this is "distortion" coming from my headphones, and therefore is sign of a broken headphone? Or if it's just normal from either the recording and/or the source? Is a broken driver really obvious?
