Wow, I was amazed now! Lightweight, almost floating to wear. You hardly feel - from time to time the ironing shift behind the ear (suppressed after a while slightly, but only slightly). Sits still rock solid - you can even shake his head, he just sits firmly. And now I catch myself that I still hear concentrated than expected.
Throughout the spectrum of sound balanced: all there, bass, middle and treble. Not as dark as some other matched KH. Everything sounds kind of consistent, airy and light. Of course, a large open KH has a bigger stage, more transparency, a higher resolution, but the size and the price already amazingly well.
I find myself now, I more and more often only once reach for this model because so straightforward and surprisingly good sounding. Really fun, I have soooo not expected.
Incidentally, I hear only 320kbit encoded MP3s or FLAC files. Stylistically tearing everything and down and back and forth through and over the bed. This KH optimized music style fun. Smartphone cable operator I do not need.
A strong buy recommendation from me for an open, lightweight KH with excellent sound. Of course, in a noisy environment unusable (tested in public transport), but in fairness it must be said that it was not designed for it. Sennheiser: everything right!
