I want to try my hand at tweaking my own settings on my Oticon More HAs without going to my Audiologist. This includes updating my firmware as I’m on 1.3.0 and 1.4.1 is out.
I see that it seems to have gotten easier with wireless programming on modern HAs and you need the NoahLink Wireless device.
I see brand new units going for $185-$250 on eBay and used units for like $125-150.
Then I see all sorts of listings selling them for $120-150 but shipping from China. Example for $137
Are there any gotchas to worry about when buying one off eBay in terms of the unit itself or are they all the same if they list the NoahLink Wireless unit and accompanying USB cable?
Second question is I’m unclear whether I can update firmware wirelessly or if I need cables. The forum posts I’ve found about this day cables are needed but they are about the Oticon OPN and a few years old.
