The unboxing experience for these was excellent. You get a lot of accessories and a premium case. The build and fit are excellent. The sound...these are very balanced sounding in low impedance mode (which is my preferred mode). The high impedance mode can cause the upper mids and treble to become a little too forward for my preferences. In low impedance mode, these sound amazing. The tuning is very agreeable and I think most folks will love these IEMs.
