So I have been thinking about getting some decent headphones, primarily for use with an iPod. I was thinking about getting some in-ear sound isolating ones to help keep things nice and quiet when I travel or study. I understand that many people consider on-ear models to be much better as far as quality goes, but maybe a set of those will be the next step if I like how this works out. I was wondering if anyone had any recommendations or anything for a set that would run less than $200 (and preferably less than $150). I listen to a bit of most everything, and believe I can deal with bass that's not overly powerful. I also don't need total audiophile quality or anything, as whatever I get will be better than what I'm used to, and my files are only encoded as like 192 or 256k AAC. I know I can pick up a pair of Shure E2c's or Etymotic ER6i's on Amazon for like $65 or some E3c's for about twice that. I don't really know what else is available that's any good in the range I'm looking at. Anyway, any help that anyone can provide would be much appreciated! Thanks, guys (and gals).
