Open Dome 4.0 S (Small)

Domes 4.0 are the domes for Phonak and Unitron hearing aids. The domes come in four different versions: Cap Dome for narrow ear canals, an open version, a closed version and power domes with double membrane.

All three types of domes come in 6, 8 and 10 mm in diameter, respectively.

Replacement of the domes ensures optimal sound quality and prevents eczema and discomfort in the ear canal. Domes should be replaced at least every 4 weeks, or as needed.
