I wear hearing aides every day. SMALLER would be better and mine have BT5 and rechargeable. they are NOT cheap about $6k pair with 3 year complete warranty included. Again having options is the best thing, making them larger for me would mean they are more easily dislodged when I bend over to pick something up or are wearing them when working in shop. Having some that have better weather or fully waterproof would be great. I normal take them off when working outside or in the shop. The sweat makes them mostly useless because of the "noise" the sweat makes against the mics. Then the sweat also makes them slick and they will not stay in place. Having options is ideal and affordable options would be great. I don't know why these things are $6k pair when they share a lot of tech with modern in ear options from bose/apple/ect.
