PHONAK / UNITRON - Replacing Dome and Filter


SIEMENS - Replacing Dome and Filter

The domes will easily slide over the ear canal end of the tubes and so are simple to replace, but they fit snugly so they do not come off when you need them to stay in place. The measurements are based on the widest part of the dome, so measure the widest part of yours to ensure that you get the right size when ordering the replacements. This is because there is a selection of sizes to choose from and you will need to get the correct size to fit.

The small open domes are 5mm, Medium open domes 7mm and large open domes 10mm. Then there are small, medium and large closed domes in 5mm, 7mm and 10mm sizes. You can also get a tulip for feedback control, 9mm power, 10mm power and 1mm power.

The replacement domes are non-occluding and comfortable to wear. They can be used with Unitron and Phonak tubes. It is important to check the compatibility so if you are not sure, contact us to check that the domes with work with your device. You can phone or email to get customer support and check the details before you buy.

These replacement domes mean that you will not need to replace your hearing aid so often. When the dome gets damaged or broken, you may think you have to replace the whole hearing aid. However, they can be replaced and if you purchase this pack of replacement domes you will always have spare ones for when they are needed.

You can choose a pack from our selection of sizes and types to make sure that you get the right one for your hearing aids. There are small from 4mm to large at 12mm as well as a choice of open and closed domes. The closed domes are best for those with severe hearing loss with the open domes cause an occlusion effect.

The set contains 30 domes so you will be able to make your hearing aid last a lot longer by replacing these parts rather than the whole hearing aid. You should find this replacement fairly easy to do and it will passively extend the life of your hearing aid; making it much better value for money than it would be if you replaced it every time a dome stopped working properly. These are compatible with many brands such as Phonak, ReSound, Widex, Oticon, Rexton, Siemens and Unitron.
