I have hearing aids as well - trying to get a new pair dialed-in. I am told that I might be able to get a pair of aids that essentially turn the protection on instantaneously (what, speed of light?) in response to loud noises, then off again when the loud noise abates.I have hearing aids and use the 3M over the ear. They work great. The hearing aids can connect to my phone to play music so no need for any music in the earmuffs.
They are custom fit - molded in the ear things (I think he said the battery/electronics sits outside as with 'normal' aides.
For the record, I got the THREE M headset ($23.50) and they work great. It got so quiet immediately. Road the tractor down to yank out a 20' 20" caliper walnut log and, save for the bumpy ride, it was like driving a Cadillac. Can't hear the Husqvarna 24" saw at all!
Oh, forgot to add I was wearing eyeglasses (well, kinda hafta!) and the 3M Ear Muff things didn't impair my vision at all!
