So I gotta brag a little here real quick. I bought 2 pairs of the 9927's, recabled them with some better quality wiring, and burned them both in. Currently, I use whichever pair I grab, paired with my FiiO E6 ( clipped on the back of my pants ) as a true in-ear setup for when I'm drumming. The E6 on the blue EQ setting, hooks into a Rolls Personal Monitor amp, which sends my mix from the board. With the whole setup, I'm incredibly happy. No more ear sweat from using the old on-ear cans, the IEM's sound AMAZING!, and overall, I'm very happy. I've had a couple musician friends try to tell me that there's no replacing a quality set of IEM'S from Shure, and while I did try theirs....Idk, for the price, I'm really liking these little butt-kicking gems!
