Happy New Year to all,
Question… does anyone know what the SF number means on these molds? My older one shows SF1, while my new ones shows SF3. Tnx
I believe that refers to “SureFit”. Current Resound receivers for Resound One etc…. are SureFit 3. At some point I think they changed the fitting of the domes from sf1 to sf2 to sf3.
