Against my better judgement, I’m joining the fray. I’d agree with Volusiano that the Velox platform was designed for the Oticon Opn. If I understand correctly, the same hardware is used for all 3 versions of Opn: 1,2, and 3. The only difference is software.
Considering we’re talking the same overall company producing Oticon, Sonic and Bernafon and that the hearing aids look very similar, I don’t find it much of a stretch to believe that they use the same chip as the Velox and use significantly different programming. They are programmable computer chips. Just because it was designed for the Opn doesn’t mean it can’t be programmed very differently.
What are the other options? They design another chip for the Bernafon and Sonic? Seems unlikely for such a relatively small company. I’m guessing the cost of making the chips is actually quite low. Other options: they use one of their older chips (Inium Sense perhaps) and combine it with their bluetooth chip? Perhaps they buy some generic hearing aid chip?
I have no idea, but gut says that using Velox platform for all likely makes economic sense, but I’m just speculating, as I believe everybody else is.
