I was skeptical, I ordered a few different IEMs and not only are these lightweight but they offer a completely different sound compared to other IEMs in the same price range. I think what ultimately sold me was the ear fatigue was just NOT there. As compared to the other IEMs where I could only use for a few hours before I needed to rest my ears.

Really nice for music,especially classic muisc,i had a hd800s and compare to the ie-900s,hd800s is heavier and really hot when summer!Obviously ie900 is more suitable for me, because I hate hot summer, so a small in-ear headset is more suitable!!
