Historical Starkey HA's



I have the following pairs of HA’s:
WI-110 which I wear now.
Series 7
Series 3
Intro 5 by Nuear

I tested these and with the exception of the Nuears, the tubes are interchangeable. I’m wondering of any of these models are newer than my 110’s in which case I could upgrade.
Can you id these aids and when the manufacturer brought them out?
I have the software and the device to program them, just need to know if it’s worth my time.



my mom has the series 3 (hers is an i30) I hope you’re loving them too
