Based on the description, this doesn't seem plausible. If the button is as clicky as it sounds, it would hurt your head/hand/both to do the thing you describe.

It doesn't matter if it's plausible or not. It's the fact that it's non-rechargeable device with 12 hours of recording...

I wouldn't think about the total recording time so much as the actual usage you'll get out of it. If based on typical usage, you could get even eighteen months out of it, then you're looking at around $5/month for a device to serve this purpose for you.

Is that worth it to you? Perhaps not. But plenty of us pay similar amounts of money for software subscriptions related to productivity, so it's not especially outlandish compared to paying for Standard Notes, Todoist, etc.

I sometimes speak into my voice recorder when I’m out for a walk and have a thought. Those voice notes can be many minutes long, and full of repetition and silence.

When no one’s looking obviously.

Not sure how that would work with the ring. Either lots of small similar notes. Or a dead battery.

I don't think that's the use case they're aiming for. If you want to have a meandering voice recording that lasts minutes, the friction to pull out your phone is less of an issue while you're out walking your dog.

But when you're having a conversation with someone and they ask you to pick up milk from the store later, or you're running to the bus and want to just jot down an idea you had briefly, and other moments where the friction is higher...then this seems like the solution.

Sure, but these use cases do blend into one another. And I'm not sure how useful the device when only constrained to the very short end of the spectrum.
