Example of the issue starting on stealth pads:
This issue has affected multiple (if not all since the Aeon?) Dan Clark Audio headphones. I don't see evidence that having a different material on one side as the only change will prevent the foam twisting underneath the pad, which is what happens to Dan Clark Audio headphones.
What? That's not what you told me over email, these are the replacement pads, and I had to buy them full price. What is going on here?
Shady business practices and bit of damage controle perhaps!
That's the driver reacting to the pressure. If you don't like it stop pressing on it.
That sucks, and is considered a warranty issue. Drop us a note and we'll replace those pads.
Sewing has tolerances, folk, normally it's +/-2mm for a lot of pad vendors, we've managed to get it to +/-1mm but even then a sewn seam will almost never lay on the sharp edge of the foam, it will usually go to the outside edge causing a bulge. AEON pads are very narrow so foam movement is more of an issue because the ration of seem size to contact area is lower so the foam can more readily shift, most pads do fine but not all do and we will cover problems like your photo under warranty.
Lastly, the larger the pad the less likely the problem. It's a question of ratio of seem to surface area of the top surface to the size of the seem, more or less. A fat round pad won't move because there's a lot more surface area relative to the seem size. But then you have a bulkier, heavier headphone that covers a big part of your cheek.
The Stealth pads are wider and therefore much more stable and to date I am not aware of anyone having a problem, and the photos that have been "shown" on other sites are not indicative of anything other than normal tolerances.
that's a stupid excuse tolerances as argeuemny - don't forget you are charging 4k for these. It's like buying a Ferrari and saying sorry we can't offer confortable seats because our tolerances won't meet the critareia.
