Bag of 10 Phonak 4.0 open domes, available in small, medium or large sizes. Please note: these domes are only compatible with Phonak Audeo M (Marvel) receiver wires.
If your Phonak hearing aid is not an Audeo M (Marvel) product, you will need to select the older Open dome (now referred to as 3.0). There are also Phonak 4.0 Vented, Power and Cap domes available.
Suggested replacement every 6 – 10 weeks, depending on use and maintenance. Always ensure that a new dome is pushed firmly onto the receiver wire before inserting into the ear.
If you are not sure which dome you have, please do contact us for assistance.
