shure definitely makes some of the best earphones, and have been one of the earliest players. E2C was one of the first and only IEMs(in-ear-monitors) to fall under the $100 price range for a long time. For a while, they were the only choice on a budget IEM.
Now the DAP market has exploded, and so has the IEM market.
I think there are a lot of other great competitors to the shure now, many at a lower cost.
I personally owned the E2C. They're decent phones, except for the highs, which sounds a bit hacked off at the top. There's a mod on headfi though, that people have greatly improved that. Mostly by cutting the stem so it's shorter, to eliminate that tunnel sound that's signature to the E2C.
OP: what kind of music do you listen to? different earphones have different sound signatures.
