Thanks Louie.
Yes, the intentional opaqueness is concerning. It may even be in breach of Fair Trading - but who is to bother to force them to be transparent.
I approached Hearing Australia because historically they have cheaper prices than the independent providers. SpecSavers are the cheaper than HA, but they do not handle ReSound.
However, it turns out that there is an Australian chain provider - Hearing Savers - that dispenses ReSound, and they quoted me just recently a slightly cheaper price for the genuine ReSound brand Custom than what we are paying for the whitelabeled product.
If it was up to me I would return the aids to HA and go for the genuine aids, but my wife does not want the hassle with that unless we find out that there is significant difference. Also, the HA audiologist is nice and is doing all the right things like REM.
Back to the fitting software, whatever it is - if it does not show the technology platform, maybe that will be enough for my wife to say thanks and goodbye to them. We still have several weeks when we can get full refund.
I have no idea how whitelabelled products fare in comparison to genuine brands in terms of features and future support, the smartphone app and firmware updates, etc.
That is what concerns me.
