CS44, CS63/64, CS 53/54 cables

CS44 has a plug to plug into the hearing aids, CS63/64 is for flex strips, CS53/54 is a flex strip adapter that connects to a CS44 to convert it to flex strip type I believe. Different hearing aids just use different types depending on their size, brand, etc. there’s really no functionality difference between them, you just need a specific cable for a specific device.

I can’t answer your question, but the way to approach is when you know what hearing aids you want to program, go into the fitting software and find out what cables are required. There are subtleties that definitely create problems. For example Phonak cables are pinned out differently.

Spot on explanation. Thanks
