First, people do lose earrings. But I know many people also do remove stuff like that for things like exercise where they might be lost exercise. Not really an option here. Also, yes, while you might immediately notice that doesn’t mean it’s immediately retrievable. For example, I wear headphones out mountain biking.…

Except they still don’t have to buy/provide it over and over for every consumer outside replacing broken equipment. No matter how you spin it it will never be an apples to apples comparison with other utilities. Other utilities have infrastructure costs as well as the utility itself needing to be generated.

Oh, come on. Something like this is going to be used in all kinds of places including out running, biking, etc... Plenty of places where one could fall out and immediately be lost. Just being small isn’t the only factor here.
