Maybe i wasn't clear: the problem appears for troops that use them in war zones: essentially days on end, not merely hours. If it was just the foam type used, I'm sure they'd try and mix it up with something more soft. That was a huge contract that was partially cancelled.

I've always worn hearing aids, with ear moulds. They're worn all the time, except for sleep. Other deaf people I know, wear them while sleeping for some odd reason. I couldn't fathom to wear anything while sleeping!

They've never made my ears bleed, nor anyone else I know.

Maybe troops should wear properly fitted moulds :)

Well, you do take them out 8 hours of the day then. Here we're talking 24/7 in dry desert heat.

Hmm, yeah. That's some pretty interesting insights though! Thanks for sharing. Then it wasn't the foam, it's probably that their ears got irritated from that plastic housing - I've learned a LOT about designing for the ear these past months and that shape is not ergonomic, haha!
