Beagle I just want to mention that personally I'm not experiencing any problems at all with getting my HD 820 to sit right on my head. I've noticed as well though that by simply opening my mouth the bass completely changes until I close it again so I understand your frustration.
First experience with the Dekoni Hybrids on the HD820: very comfortable, more than the original ones. Plus the headphones sit better on my head. The positioning issue is gone! They always immediately sit well now.
They are a bit thicker, which may be part of the reason they always sit snug.
Installation was under 1 minute...
Sound is no real difference with the originals.
So, they can stay, because overall it’s an improvement.

I knew they'd do something with all those leftover HD630VB drivers...

It's nothing new though, and certainly not a bad thing.
This kind of dip between 200-300Hz can be found in other well loved headphones like DT770 and HA-DX1000.
Usually I find this kind of response curve to be very pleasing, as it has the effect of reducing the thickness in the bass and still produces a textured low-bass response with impact.
Agree, and as Jude pointed out, it is supposed to be that way, it was designed for that particular response. A "proper" headphone response should be uneven, in the right places.

Can you post a link to them for purchase?

Thanks!

I thought you said before that the Z1R had a bit of an 8K treble spike? I don’t see that in this measurement at all. I guess it’s like about 3200kHz.

From memory to all of those who are now afraid that the HD820 has a Z1R like bass, rest assured, the perceived bass on the Sony is much more intense. Much more.

And extremely clean and controlled for a closed back. I don’t think any other closed headphones can do this

i'm not sure what constitutes a "proper" headphone response but i doubt that an uneven fr approaches it

A bit of a weird question but I'm intersted in some opinions.
Let's say the HD800S costs 1500€. How much would you value the HD820 at, the full 2400€ or less?

When I saw the HD820 graph, I was reminded on the HD8DJ graph on Inner Fidelity. It shows the same dip centered around 250 Hz. I had it for a short period of time and found it quite good sounding.

You need to try more closed phones. The Z1R is fun but hardly the very best in bass quality and many instance the bass is always there when it isn't called for. I do enjoy the Z1R but a properly driven HD800s killed it handily for me. Driving the HD800s out of a portable device doesn't not count no matter how good those DAPs are.

Want to add that what is special about the Z1R is it's rather impressive soundstage for being a closed headphones. If Sony had the ability to chop down those 200 year old Zelkeva tree, I am sure that they would have done that in a heartbeat.
