Hi … wel every item in shop is taged to an alarm system, even when i was in the canteen up stairs my aids when funny… M y audio turned of the partner check ,not sure if this is called feedback processing, And since then I explained to my audio that I felt my aids would go quiet every so often and he said this was more then likely the circuit interfering… Not much good to me
Comfused, I think I would just like a simple down to earth hearing aids…
