I've been listening to my PFE's for about a year now on my Cowon and have decided that I would like a change. The PFE's are very clear and detailed, but the highs are a bit too crispy and slightly hissy. To fix the problem I changed to the black filters and put on some Shure olives, which do help a lot but I've decided to see what else is out there.
My budget is around $100 and would like something with a warmer signature but with clear (but not crispy) highs and with still some of the clarity the PFE's provide. I listen to a variety of music, but I do like vocals to be warm, clear, and upfront.
