AKG 812 EQ

[SimpleTheater]

Unable to find the equalization to the Harman curve for the AKG 812 with the filter settings that I did for other headphones here:
https://www.reddit.com/r/oratory1990/wiki/index/list_of_presets

I decided to try my hand at creating my own based on DIYAudioHeaven (thanks @solderdude )

So, based on the Harman curve at the bottom left, and the actual K812 measurements at the bottom right, does the analysis seem to fit. It definitely sounds better to my untrained ears then no EQ. Thanks.

. Not sure if

I would not EQ the 2.5kHz.
Only the bass response and the 7kHz peak (-6dB)

A 'flat' line is almost Harman corrected balance
So 20Hz up 5dB, 50Hz up 1dB
Add bass to taste from that EQ

How do you find the 812 generally? They dont get the best press. To say the least!

The AKG K812 has a ‘bright neutral-ish’ and ‘etherial’ tonal balance. The first impression is quite good and impressive when it comes to ‘open’ sound and details.
There is no deep rumbling bass though but bass is there, just not very present a bit subdued/lean.
Bass is light but is ‘tight’ and very well textured. The overall sound is ‘open’, dynamic and very ‘forward’ as well as ‘highly detailed’ and ‘delicate’.
Drum hits etc. are over-accentuated which gives it a very ‘dynamic’ sound.
It sounds a bit too bright and can have a laser-like sharpish ‘edge’ with some music. It is bordering on sibilance. The treble quality is better than that of its cheaper siblings.

Tonal balance comparison with DT1990A and HD800S

This measurement was supposedly made by oratory:

I don't know why it's missing from his list of presets now.

I hear you. I read a lot about them a few years ago before purchasing (gotta love Amazon's return policy). I found that the press was a little harsh on them and absolutely fell in love with them for a few reasons. One the AKG 812's have something that I could not achieve with Sennheiser 6xx's or HiFiMan's - the ability to wear them for hours without any discomfort or heat generation. Two, while bass is lacking, eq'd their glorious. Third, they're relatively easy to drive.

There is definitely a bit of harshness in treble, and I think the distortion graphs bear that issue out, but its not anywhere near as bad as some of the press say. I think some reviewers see the graph and than "hear" the problem.

I recently picked up the $10 Sony MDR-ZX110's reviewed, after Amir wrote "The result was an extremely accurate and audiophile headphone! "
For $10, it's hard to complain about anything producing sound, and it's hard to compare with my AKG's because the cost over $1,000 less, but I couldn't wear them for more than 10 minutes before they became uncomfortable, the small driver couldn't handle deep bass and even knowing the price difference, I'm happy I have the AKGs. I would love to try Dan Clark Audio AEON RT's, but they are so hard to drive I could really only use them with my RME (e.g. not taking them on a walk).

Know exactly where you are coming from. The 812 are in the "if there is a really, really,really good deal on open box amazon warehouse, I will give them a go" category for me. And I mean, a bit less than £500 territory.

Im also debating the Aeon RT Open- I have the Ether CX and rate them highly, so a cheaper but open low distortion planar would be nice to have- especially light and comfy. I wouldnt listen to any of my "home" headphones out and about and I have amps that could handle them no problem but I just dont think I need them!

Also, agree about the Sony cheapies, Amir is right about the sound, they are very good short listening/ casual gaming/ zoom chat headphones (ie , when trying to do work but needing some music ) but they are not an all day proposition nor louder serious listening.
