That pretty much explains it. IMHO getting everything to work together is not a matter of if, but when.
Consider Bluetooth 5 was announced in June of 2016. Samsung released products supporting it in April of 2017, Apple in September of 2017. Microsoft’s latest flagship product the Surface Book 2 will be released November 9, 2017 with Bluetooth 4.1.
The technology getting HA’s to work with all these things, is almost the same as what someone might want in wireless ear buds. I suggest that the market is much bigger than just the HA market. Those with vision will see the same and work towards the appropriate protocols and products.
For me, I accept that these things take time. If the latest and greatest, requires multiple expensive hardware upgrades, I will likely purchase a lower cost and lower featured option that will get me through 3-5 years of product life cycle and upgrade on an as needed basis rather than an as wanted basis. Unless of course the newest technology will make a fundamental change justifying the expenditure.
I listened to people complain for years about the difficulties of using a telephone with hearing aids (self included). After experiencing cell phone connectivity through a streamer I hear a major difference. I would have no qualms suggesting to someone that they simply get a cell phone and streamer (if needed) then cancel their land line after porting their number over to a cell phone.
