All Phonak hearing aids fall into a product group range by name eg Naida. The suffix after this name will give you the model from this range.
Suffix markings such SP etc are not a unique descriptor e.g.
SP there are versions of both Naida and
Nios- its rather like GT for cars, many car ranges have GT models.
For example, common letter markings simply mean as follows:
SP - SuperPower
UP - UltraPower
The compatible product range names are shown against each shoe.
Please note that no shoe is available for the following models of hearing aids:
- Audeo
- Audeo S
