How long had you had this model before you made the video? The foam rolling problem is already pretty bad:
This issue seems to affect all Aeon models, it makes me sad to see it affects a nearly $1,000 headphone. The foam rolling under the pad is an issue because it can affect seal and comfort, and can be a permanent deformation. Some users of this forum say they literally have try to roll the foam back into place
every time they want to use their headphone, which to me is a ridiculous thing to have to do for headphones at a luxury price point. For some users trying to manually roll the foam back into place (again, a ridiculous thing to have to even try) doesn't work and the foam rolling deformation is permanent.
I don't recommend any Aeon models anymore, for a closed back planar from Dan Clark I'd stick with the Ether, which doesn't seem to have the same issue. In fact, compared to any other headphone I've owned, including ones with large luxurious pads (Ether, Mad Dogs, LCD-X, Focal Clear), the Aeons are the only headphone I've ever encountered where the foam seems to separate from the pad, and also the only headphone I've had where this issue starts so quickly, including out of the box.
