I have been dealing with declining hearing in one ear for a few years. I recently was fitted for a single hearing aid. My other side is deaf due to a previous acoustic neuroma removal. I waited two months for an audiologist appointment at Costco. After the test the audiologist recommended the Jabra Enhance Pro made by GN/Resound. I placed an order for the RIE model. $999 with 6 months to decide if I’m going to keep it. I went home and I read up on the Jabra and Resound hearing aid line (GN). I learned that in June of this year GN released M&RIE technology with a 3rd microphone in the ear canal. The advantages supposed to be a more natural hearing experience due to the “pinna effect” and better localization of sounds. I knew I wouldn’t get better localization due to having only one working ear. When I returned for my fitting I spoke to the audiologist about the M&RIE option. We agreed that I would try the RIE for a week, order the M&RIE, and then try the M&RIE. The RIE audio was clear and a big improvement over my unaided hearing, but seemed unnatural for lack of a better word. I went back the following week and had the RIE replaced and reprogrammed with the M&RIE. I noticed the difference immediately. The sound was clearer and seemed more natural. It feels almost like my own hearing with the volume turned. up. The audio is crystal clear.
