Folks, good news. Support team answered me w.r.t. headband replacement. Their words:
The Cushions are not sold separately. They come as part of the headband assembly which is everything between (but not including) the speakers. This can be ordered by calling our parts department at 800-516-2525 option 3.
I called them and the cost of these parts are:
– SRH1540: ~$17
– SRH1840: ~$24
Plus taxes and shipping.
That’s not bad actually. Hope that helps.
Cheers,
