That is certainly a consideration. While I experience tinnitus, I’ve discovered over the years that just wearing my hearing aids reduces the effect. I’ve even noticed a dramatically reduced level of tinnitus since getting my Jabra aids a couple of months ago. Even when not wearing the aids I have noticed quite a lessening of the noise in my head.
My Jabra aids have the hardware for tinnitus management, but the Costco Smart Fit software doesn’t allow it to be implemented.
