Summary: I love these phones for their smooth sound. Lots of others, very likely including our beloved webmaster, will hate them because of their rolled-of highs. But I like that, perhaps because I always have felt digital treble has something annoyingly artificial.
Summary: I purchased these headphones in attempt to replace my sony mdrnx1b. Initially out of the package, these headphones were very flat, but as they wore in, the soundstage developed signigicantly. I kept the E2C's becuase I hoped that they would mature into a pair of $150 headphones, but they did not.
Summary: I aquired these phones in an effort to have some decent sound on-the-go with isolation, and they haven't let me down. Bass: The bass definitely isn't as punchy as a Grado, but it makes a good overall presentation. It's pretty neutral in terms of it being analytical or fun when it wants to be.
Summary: In terms of the sound quality, I find the E2's just barely able to contend with similar headphones in their price range. Thus if sound quality is your only concern, I feel you should look elsewhere as there are many better sounding headphones for the same or less money.
Summary: I bought these for isolation to use with my DAP in the library. I've used them unamped 99% of the time since at the time I found amping them with my RSA SR-71 provided absolutely no difference to sound quality. Build Quality - I've found these to be very durable.
Summary: I'm going to go against the rest of the reviews here. These are better than some earbuds out there, but don't expect big sound. They will do just fine for you if you need sound isolation or something for iPod (or some portable device) listening.
Summary: These things hurt my ear canal too easily unless I use the orange foam inserts, but they get gross and deform a little too easily.
Anyway, the sound on these was good enough for me to realize that my iPod had a pretty constant hiss.
Summary: I got these phones used with a broken plug which I had to fix myself, so I have no idea what kind of life they had before they came to me. That said...
You can do better than these phones. The sound is good, there isn't any particular strength or weakness upon which I will extol.
Pros: Well-built, relatively cheap, comfortable, good isolation
Summary: The Shure E2c overall is a good earphone. Definately better than what comes standard with most Mp3 players. I'd give the E2c's a 7.5 out of 10. I hear a lot of people in these reviews talking about how these headphones need a "breaking in" period.
