Do Phonak aids bought thru Nations Hearing have code protection?

PVC - I don’t know how you do it! Continuing to say “thanks” is only an understatement. I appreciate your distinguishing the differences between the L90 and L70, very helpful. And thank you for the link to the thread by musicians, where there was some helpful info.

$-factors will unfortunately play a major part in what I buy. If primarily software changes are responsible for the price difference between Lumity and Paradise aids (Phonak unveils Lumity hearing aid platform - #276 by tenkan), I’m hoping my audi can let me try both to see what perceptible difference Lumity would make when I play guitar.

Given my strong hope to be among you DIY fitters, what options are available to me is also going to depend on whether Nations Hearing locks their HAs! With fingers crossed, I’m waiting for the delivery of the Noahlink Wireless I ordered – admittedly a very small gamble in relation to the $-costs of dealing with hearing loss.
