I guess it’s remotely possible that some manufacturer has it almost ready to go. Why release it now when there’s no source device available for the aids to connect to? You’re just opening up a can of worms in the support department if you do. Once we’ve got a Samsung phone that unambiguously supports LE Audio AND buds from a major manufacturer that that phone can stream to, then it’s game on. People see it in action in the consumer audio space and ask if their hearing aids can do the same thing.
I find it hard to believe that hearing aids that have been released in the last six months don’t have the hardware required. I mean, would any of the people who sell Bluetooth ip to hearing aid makers have anything in their inventory now that wasn’t at least BT 5.2? BT 5.2 was released well over 3 years ago.
I would take a lot of convincing to pay full price for a set of premium aids that weren’t upgradeable to LE Audio. I’m dug in and waiting.
