I have two options for you:
If you like fuller bass: shure e2c
If you like more detail: shure e3c
The thing is the detail worth the thinner bass and the extra $70?
I have both, and I love my e3c, to me it is nearly perfect for music....but for movies or gaming (I use them on my PC), I reach for my e2c...the bass really makes them stand out for this.
If your new to canalphones and want something that is easy to fit and comfortable just to get your toes wet, sony EX-71. They are about $40, and give some of the sound isolation benefits of the Shure and Etymotic offerings, although the sound is not near as nice, in my opinion.
