I’ve noticed that I get more feedback with my left HA when inserting and removing the receiver. I’m using NAL-NL2 as my fitting algorithm, which amplifies high frequencies more than ReSound’s Audiogram+. So, one thing that I’ve mused about is whether the feedback is what’s knocking out the left HA mics preferentially - or whether the design ReSound touted that gives it a greater upper frequency range than most HA’s is the Quattros fatal microphone flaw.
ReSound does say in the One literature that they totally redesigned the microphones for the One. I have always been suspicious that Quattro microphone failures had something to do with that redesign although I’m sure ReSound would argue it’s for better hearing, etc.
I like the sound, the app, the fitting software, and ReSound’s forward-looking philosophy. I just wish I had a much better reliability experience.
