I don’t have the More, I have the OPN, which is also Oticon but a couple of generations before the More. When I first got my OPNs, they would randomly restart without any rhythm and rhyme. But after a firmware or two or three, they no longer do it as much as before (which can be a few times a week), but once in a long while it can still happen.
As hearing aids get more and more complicated, it’s easier and easier for computations inside, or algorithms, of software-based memory stacking or memory leak to occur due to bugs and instability. Once things get to a certain point of no return (not recoverable anymore), the aids are designed to just restart. It’s not any different than your computer or apps on your smart phone getting hung, forcing you to reboot your PC or phone to clear things out. With the aids, I get there’s no on-the-fly interface you get like with the PC or phone, so they probably design it to just reboot when things are hung.
As to why your Siemens never did this but the More do it a lot more often, it may depend on the level of complexity in the designs. The More has been out for 2 years already, and there have been a number of firmware updates, so hopefully this type of random restart will get reported less and less.
I’m curious as to whether you’re exposed to complex environments often? I wonder if complex environments push the HAs to the limit until they fall off the brink and are forced to restart.
I’ve had occasions when I’m at home (simple environment) and my OPN would restart as well, so I don’t know…
