Warnings :-)

1. Attention! The first few days shows that KH not nearly what he can. Major disappointment! Wanted him for returning, as bass and treble undefined shrill. So a few days import are required! Think there were at least. 30h continuous operation. Psychoacoustic effects I exclude, as I have always querverglichen me with my very known reference HD650.
2. Attention! Then this can make KH addictive! The fantastic dynamic and well balanced, for a closed KH quite spacious and finely audible sound are outstanding. A real KH the joy of music conveys and presents the dynamic aspects without shrill height emphasis. Surely even the slight emphasis on the bass and the madness print this bass owed, on the other hand came to no comparison listeners (HD650, P5, iGrado, MDR-1).
3. Attention! A clear to me sound improvement can be achieved by changing the cable, (some shell micro latch needs to be adjusted a little! Carefully remove the cutter) have the (somewhat stiff) Fiio RC-HD1 try and feel the tighter bass and less hissing heights thereby transparenterem middle area and in particular the significant increase in dynamics and definition better, do not know why the Beipackkabel all no good. Beginning at P5 way.
4. Attention! There are of course better. At the fantastic space and mid resolution and loose sovereignty of the HD650 P7 comes not ran. And the cost (less beauty) currently less! But has it not the joy of B & W. Not even the rather middle fell P5. Therefore price / quality relation solid 4 points.
Listening environment: iPad directly and with E12 (MP3), Fiio X3 (Flac)
