On one hand we have this.
On the other hand we have genuine Bose replacement cushions that start to flake out not two years after very light use. Not aftermarket, but their own ridiculously expensive units bought directly from them. I have no explanation for this except for it being due to planned obsolescence practices. So they can publish as many reports (that tested a whooping 10 returned units!), but it doesn't undo the ill will created by their products falling apart on schedule. Caveat emptor and all that.
