I'm currently looking for a good all around iem for under $90
I listen to a variety of music, from classic rock and psychedelic rock to hip hop to electronic.
My current listening experience (and the best sound I've experienced thus far) includes a pair of JVC HA-S500 headphones. These sound phenomenal to me.
So far, my favorite iem's have been a pair of Brainwavz M5's that were comfortable and enjoyable to listen to, but unfortunately I lost them.
I'm strongly considering ordering another pair of Branwavz M5's, however I'm considering any iem under $90.
If you are looking for a very low cost temporary solution until you find what you really want, you could pick-up a pair of Mee M6 for under $20. They will NOT compare to something like the SE215, but they aren't horrible - and they are comfortable over-the-ear style IEMs that are easy to drive & very cheap.
