My first impressions that can not yet be final. And, I accentuate always, these are my personal impressions without any claim to absoluteness!
High-quality packaging, covered with black cloth, hinged lid, fully molded tray, headphone stand made of laminated wood.
The essential parts of the K812 Pro headphone are made of high quality aluminum. By a gimbal mounting, the seat fits perfectly on the head shape.
The bracket can be adjusted by means of screening. The seat is good.
The K812 Pro is designed as an open headphone. The openness is not visible on photos, because the perforated back cover is additionally covered by a fine mesh, the driver is also protected by a fine mesh. In a way, in my opinion he is closer (in terms of openness) to the legend K1000 than the K/Q7xx series without its disadvantages. Of course, with newly developed 53 mm drivers of all previous innovations (eg, magnet 1.5 Tesla, lighter coil wire, etc. ) are included with.
The pads have approximately the same inner diameter as the K/Q7xx series but are constructed differently, include the ear perfectly and closed with a kind of lip to the head. The cover of the pads is velvety, leathery (a reference to which material they use, I dont found), comfortable to wear .
Tonal the K812 Pro are best headphones I had in the house to test so far. It is in any case to be classified (ranged) over the Denon D7000 (also ranged over the Beyer T1 as I could compare this with in the pre-test ). This refers to my test of pilot run model ( AKG ) and the first hearing impressions and does not constitute a finally statement.
As I recall, he is tonal ranged over the K1000 legend. Alone, the bass of the K812 Pro ranges noticeably down much deeper . The comparison with the K1000 regard to the openness of the stage I can not reproduce, since I have no K1000 available and memories I want to leave me any way.
The K812 Pro is neutral as it should be for a studio headphones, but also relentlessly against bad recordings, errors in the recording - which indeed corresponds to the actual purpose .
The audible sensitivity - my headphone amplifier WNA MKII with 15 Ohm output impedance is the difference in volume level for K712 Pro rather low, I just have very little to regulate (direction down) to the same volume to achieve.
........
First impressions sound to see with caution since no burning in period.
Sara K. " Hell over high water" SACD -DDD
Tend to track a noticeably brighter and richer in detail and better, finer resolution than the K712 Pro.
Neutral, profound, punchier but not over emphasized bass.
Liszt Orchestral Works , 2CDs , ADD
Berliner Philharmoniker , Herbert von Karajan , recorded in 1961 , 1968, 1976
Very high and fine, detailed resolution of sounds. Expansive deep bass, dry, without the boom in the mid- bass range (as sometimes occurs when Denon D7000) .
Comparisons and impressions regarding the spatial representations stage will coming soon, please be patient, I will check here some of my impressions after a few days again. Now I'm a few days so just listen and take notes. If I heard, "a block of my test pieces", I report. So far as I always did with my hearing test!
Photos will follow soon, I need to edit (examine, reduce resolution).
PS: Regarding the Availability, as far as I know, next week the first copies go to the dealers and processed the pre-orders in order. The production in Vienna operate at full stretch. Please bear with!
