These are replacement tubes for the Sonic Innovations Hearing Aids only that are fitted with the miniFit thin tube system. All Compact Power Plus, Power and Nano BTEs apply. These domes slide over the end of the tubes. Although the domes fit snugly on the Tubes they are easy to get on and off.
To get the size you need, measure the widest diameter of the dome in millimeters. These domes come five to a package (5) and are available in numerous diameter sizes.
