I told my wife's uncle about the biometric EarPods. He happens to be one of the most renown ear specialist in the world. His response: it actually makes sense, it's 20 year old technology. Apparently, you can measure things like oxygen from your ears. Quite possibly other stuff as well. I personally think it's be a great to see something like this exist one day.
