Hate to bump this, but I think now I may be considering an IEM. I don't know how well I'll take to it, but I've been using a cheap set of MX300's I bought from J&R the other day, and I really like the portability of it. They sound kinda crappy and don't stay in my ear very well, but I think I wanna give something a bit more high end and in-ear a shot.
I'm considering the Senn CX300 or better yet the Creative EP-630 (since I've read they're basically the same but cheaper, have a Y-cord, etc.), but I'm just wondering how easily the foam tips come off? The foam pads on both my Creative stock buds and MX300's constantly fall off when I take them out of my bag, and I would love to have something small that won't have that problem.
Oh, and what's an IEM like anyway? I know they say the sound is like in your head, but does it sound tiny, like earbuds? Does the bass really thump? Thanks, guys.
