Received my K812 Last tuesday, gave them a few minutes of listening . I'm back to my headphone rig today , so I'm able to give more listening time ( 2 hours) to this K812 against my HD800 - Metrum Octave , Sonett Rig

Currently Using some Classical, Tech House, Funk-Jazz and Folks/singers

- Definitely Rough Treble. Not too bothersome for people who are not too sensitive in this area.  I could easily live with that treble personaly. It Reminds me the best Ultrasone Trebles  :)p13 but the issue is obvious to my ears. especially with strings.
- Something "Boomy"/ not clean enough in the Bass Area. More Noticeable with a Fiio X3 and Less with the Sonett. Despites specs, I think those headphones need a serious amp to control better bot bass and treble. HD800 bass is tighter but On some recordings it seems my HD800 give more bass quantity and sometimes less.
- Good overall Balance. A bit less bright than my (unmodded) HD800. This AKG tends to me very slightly Fun/V-shaped.
- The Soundstage is good . it shares some similarities with the HD800 as Marvey pointed before. Need more headtime to identify more precisely
- Lacks of Dynamics IMO. it sounds a bit soft/polite while a HD800 sucks me more in the Music. A kind of AKG Home Sound
- Extremely comfortable headphone but the clamp is too loose for my tastes.

Overally. I Like this Headphone way better than a Beyerdynamic T1 for example although I definitely think that the Beyer does many things better ( Soundstage precision, layering, dynamics, energy/impact)  I could definitely live with it but I'm maybe not as picky as other pyrates ;)

I'll see if my mind change in the next weeks. the final buyer waits the headphone.

I agree with most of what you wrote, but probably liked the K812 subjectively more than you did. I like it quite a lot and did not experience a lot of the problems that others have reported, although this could be due to relative insensitivity to treble issues; music selection; poor upstream gear actually hiding the 812's limitations rather than highlighting them; lack of good comparison (I don't have a high-end (well any for that matter) HD800 setup, although I have heard may such good setups over the years). In fact, I tried to track down some of the problematic tracks mentioned here an at IF and did not hear what the big deal was about. Again, I am willing to accept that could be my own limitations and I certainly accept that measurements seem to support a lot of what people ar efinding problematic in these cans.

Without a side-by-side comparison I am not certain whether I would prefer the K812 or the T1. I would likely prefer the K812 given its better IMO soundstage capabilities. However, a used T1 can be had for around $750 I think and a "good" price for a K812 is still $1,100 - 1,200. So, it is hard to justify the K812 between those two given the price differential. OTOH, the K812 is easy to drive and sounds surprisingly good out of even an Iphone, something that cannot be said for a T1 or an HD 800. I could be happy with the K812 out of my Marantz receiver and I am sure that would not be the case with either of the other cans.

Marv, please feel free to send the K812 around as a loaner, just be sure, folks, to let me know where they are as they move. Thx.

Hey, Tyll. The K812 is already circulating as a loaner. It is on its way to Takato14 who should have it shortly. Not sure how many people are left but I think I was last person on east coast part of tour as I sent it off to the Midwest.  Thanks for allowing this tour.

Someone else concludes like me to the lack of dynamics of this K812 ?  Someone did try it on different amps ?

It seems I need to crank up the volume all the time to try to find enjoyment and then the only thing I find is treble harshness. I'm currently listenin to Chick Corea's "the Vigil" and cymbals make me cringe a bit

Despite Bass and treble issues , the K812 is enjoyable but a bit boring/Too polite? . Nothing terribly wrong ( apart maybe those treble issues) but nothing really impressive . Definitely not worth 1500€ IMO.   Thoughts ?

Yeah, they really do need some extra gain to sound their best, though this is not necessarily an inherently bad thing. Lack of dynamics, conversely, is, and I noticed that as well. A little compressed sounding. I however did not find the highs harsh or unpleasant, not even with some of my most aggressive songs, just overly rough and piss-poor/low-fi sounding.

This pretty much. Not a bad headphone, but unremarkable in just about every way. It's not that it's "too polite", which imo is impossible, but the resolving capabilities/micro-detail/timbre accuracy/realism that usually come with a headphone like this (HD800 or even HD600 and Q701) just aren't there.

Personally what I think happened is that either Harman horned in on AKG's project and ruined the product, or AKG went overboard (no pun intended) with all of the fancy metals and protein leather, causing the sound to take a backseat.

Yep . Compressed. Thats what I said to a friend who owns the AKG.

it's like someone had decided to make a HD800 replica but more mass market oriented. weird.  walk the plank
