Music genres: My playlist is a little eclectic: 30% classical (instrumental), 40% pop, 10% rock, and 20% miscellaneous (I've got folk, country, opera, trance...etc.)
Portable: Yes. If I can't find one that'll fit all criteria, I'm open to getting one for hauling around campus and one for home. I listen from Sansa Clip when I'm out and just from the computer at home.
Price range: <$100
Headphone preference: I would like to avoid IEMs. I used the Koss-ksc75 for errand running (because I can sling it about without worrying too much about it) and I liked it well enough, but the treble gets a little too bright for me sometimes (plus the clips kept unsnapping). I kind of lean towards the darker, richer (is that how you describe it?) type more.
(And just as an aside, I like doing things to my headphones, so if anyone can point me in the direction of portable headphones that I can mess around with, it would be a plus and much appreciated.)
Once again, thanks for your help!
