As to the question of comfort, it is certainly and indvidual thing. I just bought the E2C's. I find the sound to be quite good and the comfort fine. I forget they are in after a bit. Am busy ratitionalizing the purchase of the E5C's. It'll take me another week or two! Good sound is transporting and listening to something really fine is as good as a two hour nap! (See, I'm working on it!)

If yo buy directly from Shure's web site, there is a 30 day no questions asked return policy. Should be enough time to see if you like 'em.~

Best wishes,
