I'm in my 60s but wear hearing aids from hearing loss caused by loud music days in the 70s (lol). I love them. When I am on deck and its windy, the "sound" of the wind plays havoc with them as they try to "self-adjust" to the noise. I've tried a variety of hats and headbands, scarves etc ... Then I discovered ear plugs. I keep a pair in my pocket and pop them in and out as needed and it works terrifically. MUCH easier than removing the hearing aids and more comfortable than a headband.
My audiologist said no problem, even suggested trimming the ear plug down a bit if more comfortable. PS I always take my hearing aids in for cleaning after a cruise as the ocean air takes it toll on them.
