I’m a jazz guitarist with significant high frequency loss as you can see from my audiogram. I have excellent pitch discrimination in my range and my guitars always sounded spot on.
Yesterday I received my first ever pair of hearing aids, the Costco KS8’s. The technician told me there’s only one program for the KS8 and he dialed it down to allow me to acclimate over time. When I picked up my guitar last evening it produced a warbling sound similar to having 3 strings tuned at slightly different pitches plucked simultaneously. I doubt that increasing the volume and high frequencies will correct this. As a musician, it’s completely intolerable.
From reading the forum here, it seems the KS8’s do come with more than one program and others have mentioned a music program which I can’t find. Nothing is available from my two apps for my Android phone, in fact one app hardly works and the other can only adjust volume, not tone or directionality. I think this is a phone compatibility issue; I have the Nexus 5x and it’s not listed as a supported phone. I can live with this or get a more compatible phone, but if pitch shifting in music can’t be corrected, it gets returned ASAP. Maybe I have to “upgrade” to the ReSound Forte?
