30pcs Hearing Aid Retainer for Eyeglass Users - Anti-Lost Glasses Connectors, Adults & Seniors (White/Black)

The problem I had was that it didn't hold the hearing aid in the same place, it would move and cover the mic.

I would say these would work really well for someone without tremors. But as it is does not work for my mil because of her tremors.

The gold wire on the band makes it impossible to use as a hearing aid retainer. Try using a orthodontic rubber band. The actual count of bands received was 28, not the advertised 30.
