You should click the links above and do some reading because I don’t think these cables will work for you.
- ReSound uses CS44 cables.
- Phonak/Unitron uses CS44a cables.
The difference is that Phonak/Unitron has pins 3&4 are reversed for some obscure reason. Though, if you have some wiring skills, maybe you could build a DIY Converter to get your INTERTON/RESOUND CS44 cables to work for Phonak.
Now I’m not 100% certain that pins 3&4 reversal will make your cables non-functional. But that is what history has shown us for other non-programming-pill connectors such as direct cable connections or cable and flex strip connections.
