I’d question why someone would get this over Alexa-powered earbuds. The obvious benefit is this is “always on” your face and earbuds that are only on X% of your waking day, but at least when you are alone it seems like most people would wear their buds/headphones enough of the day where no one would really feel like they would need it in their glasses over headphones. Headphones are also an easier sell to a wider population of users since they’re relevant to all vs a subset of people who need or want to wear glasses.
