That's a great question. Normal use. I baby my headphones - but then all of them bar the Elear use leather wherever they touch skin/hair, and as you know, leather is exceptionally resilient with just a simple wipe once in a while. I think there's a reason Focal used leather on their $4k headphones.
The pads on my Elear compressed before the material started fraying, which I have no issue with - all velour/material pads wear out over time and need replacing. But the same applies to material/velour headband padding. Mine isn't too badly worn, and being dark, it's hardly noticeable. But I can imagine in a year or so it'll be far worse. I have quite long, sometimes oily hair, and short of using a headband protector or head covering (which you shouldn't have to do with a high-end headphone!), I see no way of preventing further wear. Which is why I asked the question - how can wear be minimised through regular use, and how can it be resolved if the headband is non-replaceable/serviceable?
The Clear is relatively new, but I can imagine with repeat cleanings, the material will ultimately start to discolour and/or fray over the course of a couple of years. At least the pads you can replace (price notwithstanding), but the headband you're stuck with. As a responsive and knowledgable Focal agent I was hoping you'd have some answers/suggestions, because my repeated emails to Focal have drawn a blank.
