I’ve been wearing Phonak Audeo Infinio hearing aids for six weeks, and on a couple of occasions, my wife noticed a high-pitched sound coming from them. Interestingly, I couldn’t hear the sound myself. Both times, I resolved the issue by powering the hearing aids off and back on.
Does anyone know what might be causing this? For context, this occurred with both the Infinio Sphere 90 and the Infinio non-Sphere 50 models
