The physical appearance of the K872 looks like the same as K812, but with little differences. Contact pressure of the K872 a trace less, but I can not measure and confirm this. The external damping is very good. I hardly hear the opening and closing the CD loading next to me. The holder of the ear pads and the cover of the converter is changed compared to the K812. The ear pads can be removed only by means of a small enclosed tool - the reason is the required tightness. The K872 is so I was assured, fit with injected cable in the case, had this...

  20. October 2010 I can not wait and all notes and "warnings" to spite, I made a sound check with no burning-in. After about 1 hour a very detailed sound, more detail than the K701 - but I've known from the test of the K702 and has no significance - it will show whether the stops. Music: Marianne Faithfull - Blazing Away Pink Floyd - Final Cut Phil sings Maria Ola Magnell - Malvina   Short cross-check for K501 (which I bought used) - very musical and relaxed - but a bit less detailed.

I post all my reviews in this thread http://www.head-fi.org/forum/thread/333953/denon-ah-d7000/315#post_5172055

After burning in the K702 sounds me very similar to my K701 I had a K702 for test 2009

Compared to the Q701, K701, D7000 the K501 spend a very relaxed sound to me. You could here with this headphone many hours without tiredness. Compared direct with the Q701 I notice a little rolloff on both ends (treble, bass).  A very good headphone for little instrumentation ... e.g. a vocalist and a guitar and for some classic music too. It's a headphone that headphone »freaks« must have. Cons - AKG don't made them furthermore, it's obsolete.   I bought it almost good as new and checked by AKG.

IMHO - the K701 is one of the best dynamic open headphones of the except few of the expensive HighEnd range.   I own a Denon AH-D 7000  too and the difference are not so great as the price    my comparing with K702 please look this thread http://www.head-fi.org/forum/thread/359127/akg-k702-fields-of-gold/
