My first "Pro" set of IEM's. I guess I am only 2 days into this set of Shure 215's but I have enjoyed every note of my music experience. Sound Isolation is great, although I am comparing to mass market IEM's (Bose, Griffin, Apple IEM's). Price is by far the best part, at $99 I really don't think you can challenge this IEM for value. I was also impressed by the Bass. It doesn't get muddy and can kick a bit with the right playlist. I noticed that the case seems to be a touch too small for all this cord, and it's a soft case where I would prefer more...
