Hearing loss from military and HVAC/R Equipment exposure. Have Warn Hearing Aids For decades. Most ear pieces will not stay put in my ears due to jaw movement flexing of my ear canal. I am a techie and want full featured Bluetooth connect-ability. Not satisfied with my Costco supported ReSound GN’s. I am willing to pay for the best options. if I could just identify who can provide them, with proactive support. My Costco provider seems just too busy to provide individual care and support.
