What’s the target use case for this? It seems too small to be useful as a laptop replacement, and isn’t really mobile without cellular radios. About the only purpose I can see is replacing pagers that are still used in medical facilities.

Sure, but I have no idea what prices to expect in Chile, airport or otherwise. Just trying to extract some info by the author’s choice of wording.

Does he want to take a budget option away? At one point he says “And they still charge $12” to me that says that’s close to what proper wired earbuds should cost. People are getting screwed buying something that should have higher sound quality and getting the cheapest Bluetooth quality instead.
