These domes will fit all Resound Linx Hearing Aids. 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.
Note: All Dome orders are non-refundable. If you are not certain of your size, call us about a sample pack. 888-570-2740
