I wonder if this would work on k812 at all. The peaks are in different places, but the concept seems similar enough. However, the driver and housing look completely different on k812, but I have not handled it yet. Anyone know?

Can't speak on velour pads or foam rings but I'm enjoying the K812s much more with some of this in the cups.

Tor4,
Thanks for the felt tip pointers. I have a single layer of craft felt cut to exact donut dimensions of the stock foam. I kind of like it. I'm still preferring the K701 pads though.

Is the felt stiff or not? More soft or rough in texture? And is A4 or whatever a specific type of felt or the size?

A single layer of ring-shaped felt is going to do almost nothing from my tests... Also,more than 4 layers are nearly impossible to fit underneath the pads and would theoretically made the sound too dark to stand. That's why 2-4 is what I recommend.

Is the felt stiff or not? More soft or rough in texture? And is A4 or whatever a specific type of felt or the size?

Stiffer, 2-3mm thick felt... Buy two A4 size to be safe but maybe one would be enough as well. At first,fitting more than two rings will be difficult but the felt is going to adjust (compress) after a while so it won't not be as problematic anymore (though still not completely easy)'

well, i am using the K701 pads which sound very different from the memory foam, and i assume the sonic impact of the felt is going be different. the stock pads are a little too warm and bloated in the bass for my tastes. the single layer with the K701 pads adds some warmth and smooths out the trebles to my ears, but not tipping it too far in the direction of the memory foam pads.

i'm going to play around with different felts/materials, but so far am liking it as is.

I believe he is referring to the European paper size. "A4" is the designation for the euro size closest to our "Letter" size (8.5 x 11).

What I meant was that it's going to make some change but not as crucial as with 2-4 rings... But of course, my experience is so far only linked with K712 Pro and only with K712 pads.

As I am most probably going to have K701 with me for a few days, I could try to use these K701 pads for K712 Pro... Thanks for the idea!

I believe he is referring to the European paper size. "A4" is the designation for the euro size equivalent of our "Letter" size (8.5 x 11).

Oh, yes, I forgot A4 is not a worlwide term... Thank you for correction.

It's the closest size, but not equivalent.

Touche. Fixed it. Stupid, beautiful symmetry of page sizes with sqrt2 ratio.
