Some of the neoprene croakies don't have rubber sleeves but neoprene one's. I'm sure they would stretch over the ear piece but I wouldn't trust they would hold well if they fly off. Chums makes the wire one's too that have a swivel so you can bend it down to rest on your neck/shoulder and not have it sticking straight out from the back of your head and flap around. I've also seen more flexible ones not made of wire or fishing line.
