They take 15 minutes to recharge for another 3 hours of listening. Minor inconvenience.
Also, what happens when the battery dies (permanently) on these? Just have to buy another pair?
It's a shame, as if it were 10 or 12 hours, I'd have bought them seconds after the announcement.
Oh well. Here's hoping for 2017!
That said, apple ear buds and my ears never really did get along.
Sometimes, I will use over ear
For a lot of uses (for example: podcasts, casual movie watching on a long flight, getting driving directions on a road trip), it'd be entirely practical to use one earbud at a time and so have effectively 24+ hours battery life.
