I am in my fourth year with the Resound Linx hearing aids. They are the best out of all the previous hearing aids I have had in the last 19 years. The two that I help pay for through my insurance plan then, since I was working at the time, work through my mobile phone app. I purchased an iPhone so that it could work the best on the phone. My audiologist placed four different programs on the hearing aid which are displayed on the app. I turn on my hearing aids and iPhone to work the hearing aids so I can pick up phone calls, listen in a looped setting, tone down in a noisy environment, or mute out my tinnitus. I will be getting a mini mic to complement the hearing aids which I neglected to purchase at the time of the hearing aids because I didn't feel I needed it at the time. I have been losing more of my hearing so will need to have people wear the mic so I can hear their speaking into my hearing aids. Over all this has been the best investment I have ever had in my life outside of the Volkswagen Vetta which has saved my life many times. These hearing aids allow me to talk on the phone with my mom via FaceTime and to anyone as if they are right next to me. I can alter the volumes in the four programs if I need to since the thresholds have been tweaked by the audiologist to allow the changes. Its a win/win situation all around. I have mod to severe hearing loss in both ears with hyperacusis and migraine syndrome. I need to have super hearing aids that adjust and work with my tricky brain. These do that for me.
