Best in-ear headphones for around $100?

I have a set of Bose In-ear headphones that have reached the end of their life (after many years of use) and I have been doing a lot of research to find the best replacement. I have read that the Bose ear buds are very overrated and that you are mostly paying for the name. I've read that you can get better sounding products for less money, therefore I am exploring other options. I always thought the Bose sounded great but I'm intrigued with what I've read. I listen to mostly classic rock at a standard iTunes 128kbps AAC file. I also stream Pandora quite frequently. I have read that high end headphones will not sound all that great playing these compressed formats so I'm looking for the right balance.

To sum it all up, this is what I'm looking for: Ear buds that deliver a better sound than the Bose IE headphones, sound great playing standard 128kbs AAC files, deliver a rich bass sound but not overpowering, deliver a crisp, clear, detailed sound, fit in the budget of $100. I hear that shure se215's are good, but have a muddy sound compared to others. Audiophiles, what is your recommendation?
