The Ety ER6i is my lowest end IEM, but it is often my favorite.
SQ is great, as you will read all over the place, if you like a laid back sound, its not "in your face".
These are very comfortable IEMs, very light, the cord is small, yet tough, with a clip to prevent is swinging around if your active. I use the 6i for exercise IEMs, running, biking, elliptical.
