These domes are suitable for the newer click receivers. Integrated silicon grid for wax protection. Disposable solution for frequent replacement. Click interface for reliable and easy use. For patients who require maximum comfort and no occlusion. Please take care when ordering that you know what size and type of dome you require. If in doubt please ask our advice or alternatively the company that supplied your hearing aids. If you order the wrong size / type of dome but can return unopened and in a re-saleable condition we are happy to replace with the correct item, however we cannot accept opened packets that we cannot re-sell. It's a good idea if you are unsure which product to order to compare the picture of the product you want to buy with one of your own domes and also measure and compare the diameter of one of your existing domes at its base.
