I know it has been mentioned that K550 have a bright highs, I've never actually thought so myself but now I found a song that really hurts my ears. Could someone take a listen to "Nightwish - Angels fall first", does the flute really pierce your ears as it does mine? Is there anything I could do about that, mod or anything for the headphones?
what is the time of the recording that you have this issue? if you want to keep these headphones, you can always EQ the treble down a bit. that is the easiest free mod to adjust the sound signature.
