Great Headphone. Extremely comfortab.
The clue to the K812’s priorities is that they are marketed and distributed by the AKG’s Professional wing, which deals with recording studios and the music-making side of things in general. Exotic finishes and conventional judgements of luxury count for very little. Instead, reliability, toughness and consistency take priority, and the sound quality of a pair of headphones can be judged against the live event. Chamber Music: Mozart's Horn Quintet K.407 shows the 5 instruments in precise laser-cut 3D layout, with the horn in stage center. You feel you are on the same stage with the musicians, or at least in the front row. With the K702 you get the same stage width but zero depth or separation of instruments. With the HD800, the sound is very warm and somewhat distant, as if you're sitting 5, 6 rows from a large stage. Lieder/Vocal Music: Cecilia Bartoli sings "Se Tu M'ami" Bartoli with the piano located clearly to her right rear, the soundstage is close and intimate. On the K702, both the singer and the piano are right next to each other. The HD800 again sounds distant and not laser-sharp like the K812, as if Ms. Bartoli is singing in a cavernous hall like the Met. You WILL not find anything that sounds better than this. You just wont. I have been purchasing speakers and headphones my entire life and I've used the best from AKG, SONY, SH, etc..this is the real deal. On top of that, they are the most comfortable headphones ever.
