I’m wearing a hearing aid for the first time now for about a month. Just one ear works but needs amplification. I purchased a Jabra with M&RIE. I like the natural sound. Last night it seemed like the All Around setting was providing weak amplification. I put in a new battery. No change. I switched to the Restaurant setting and it was working fine. Now mind you my All Around Directionality is set to M&RIE rather than Omnidirectional as my choice due to tininess in Omnidirectional . The Restaurant is Autoscope. I took the Aid out again and gave the M&RIE microphone filter a good brushing. There was no visible dirt on it. I put the Aid on again and it was like new. It was louder that it had been over the last week. So, morals of the story are: 1. The M&RIE setting on All Around is highly dependent on the M&RIE microphone, more so then I expected based on the description in Smart Fit. 2. The microphone filter on the M&RIE receiver does get dirty even though it faces outward and leads to markedly reduced performance of the M&RIE microphone.
When I had my last fitting session at Costco, the audiologist gave me wax filters for the receiver and tulip domes, no microphone filters. I can’t find them online or even a part number from GN. If anyone knows of an online supplier or a part number, please give a shout out.
