Phonak SlimTube 4.0

When it is possible from an acoustic point of view, hearing aids are usually fitted with a thin tube. This SlimTube ensures a good fit of the hearing aid and is very unobtrusive to wear.


During the fitting, a template is used to determine the correct length and the dome that fits the ear canal is selected.


The length is engraved on the end of the sound tube that sits in the ear canal, so you can easily read it.

  • Phonak Bolero M (Marvel)
