Hi,
Im wondering if anyone else using Signia Pure 312 AX is having issues with weird sound artifacts when running the feedback cancellation on turbo(max). Often called feedback entrainment. I get loads of weird noises when trying to run them in this mode so I have to run them in normal feedback cancellation which results in feedback when I lay my head down, someone hugs me and so on. Did not have this issue with my old Signia hearing aids. Extremely annoying.
