It's not largely bassy, but the there are plenty of bass for sure(if you listen to tracks with bass) and does extend lower than the UERM, and it's pretty damn tight. I'd like to see decay graph on this iem, I'm guessing there will not be much decay. I come to realization that the mids are lifted a bit. Sound stage is pretty wide for a universal, the UERM in comparison is a bit narrower. There are some thicker treble on the lower portion which is a bit accentuated(this maybe the reason why I was reminded of the Shures a bit, but not really similar, I think the treble gets finer than the Shures). A bit aggressive iem, but it's a great performer(more I listen to it, I'm realizing more of it's potential).
