I believe you're firmly in the camp of first world problems. As far as I can tell they are the first wireless earphones to even address this problem with not one (external battery) but two (rapid charging) solutions at once.
If you're spending $159 on wireless headphones for your iPhone, you're probably already the poster child for the first world and are thus entitled to complain about first world problems.
Sure, but we're having this conversation on a forum for members of a rather upper middle class profession using a $1000 computer, talking about a $600 phone. We're all firmly in the camp of first world problems. Being extremely fortunate to have these problems doesn't delegitimize them. Nobody's saying it's on par with anything truly terrible in the world.
