@JimGnitecki , yes you can see current firmware version from the Jabra app on phone (they call it software version in the app). Below is a couple of forum discussions that might be of interest. If you look at my audiogram, you’ll see my loss in my right ear - I use a custom mold on that ear ($30 at Costco for one mold). My Left ear is not bad at all. However the combination makes it very hard for me to determine location of sound. The M&RIE receivers have helped that. I previously had a Resound Quattro, and going to the Jabra Enhanced (Resound One) with the M&RIE, was a great improvement.
It looks like Costco in the US is now able to take orders for the new Jabra 20, I’m intending on calling my Costco tomorrow and ordering one - I live 90 mins away from my closest Costco, So I’m going to buy over the phone if they let me, and go in just once for the fitting.
