Anyone know where I can get a brick of the same kind of memory foam earplugs are made of? Not that heat-reactive kind used in mattresses or pillows and not the Nerf-like foam that springs right back into shape too quickly.
Basically, I'm trying to get something that I can use to fill the speaker pockets in my helmets that will remain "squished" for long enough to insert my head but then expand and firmly push the earcups against my ears. As it is, my ears fold down when inserting my head and I have to use my glasses to correct it.
I already tried eBay and craft stores like Michaels and Jo-Anne Fabrics. The best option I can come up with seems to be to buy a bulk pack of earplugs and sew them together.
