This is off-topic but there's a fair amount of interest in audio with RISC OS still and a lot of experience so I hope you forgive the posting. I use cordless headphones a lot for sometimes extended periods. Has anybody found this causes hair loss around the earpieces? What is this, presumably skin irritation? Don't suppose there's a remedy? The obvious remedy is to use plug-_style_ headphones, which (depending on what you choose) might even help preserve your hearing, as isolating earplugs would allow you to reduce the volume. Earoplugs have their own set of disadvantages, of course. I suppose the hair loss could be caused by a reaction to the materials used in the pads; if so, other headphones might work better. A couple years back, I noticed that I had got a sort of groove in my skull, caused by the hooks on my glasses. Slightly worrying, and maybe I should worry about possible retrophrenological effects
