Phonak Unitron Smokey Domes


Phonak Unitron Smokey Domes used alongside Phonak 2 Pin xReceivers and Phonak HE Slim Tubes. They are designed to keep your hearing aid clean and sanitary, reduce the visibility of your earpiece and keep its original colour for longer.

Brand: Phonak

This product includes: x1 pack of 10 domes


Phonak smokey domes are less susceptible to discolouration and yellowing and are made from silicon for extra comfort. They also feature an integrated wax filter for those of us who produce a little too much earwax!

Although it is always best to check with your hearing aid provider which size and style you have, our dedicated support staff can also help you identify what you need. You are most welcome to either email a photo of your hearing aid dome to our experts or open an online chat with us today.

It is also possible to measure your domes at home. The base diameter of your dome will be found in millimeters, please find the dome measurements below:

Open: small = 7mm, medium = 8mm, large = 10mm

Closed: small = 7mm, medium = 9mm, large = 11mm

Power: small = 9mm, medium = 11mm, large = 13mm

How to use:

We recommend domes to be changed every one to two months, however this can vary from person-to-person. When it is time to change your dome, simply follow this 2-step process:

  1. Firmly grasp the speaker/ thin tube and pull off the old dome.
  2. Take the new dome in your hand and place it the same spot as your old dome. Push the new dome firmly to ensure that it is securely fastened.


Phonak Unitron domes are compatible with selected Phonak and Unitron hearing aid ranges, including Phonak Audeo. They are used alongside Phonak 2 Pin xReceivers and Phonak HE Slim Tubes. If you use 4.0 Receivers or 4.0 Slim Tubes, you will require the 4.0 Domes, which you can find HERE.
