Thanks for clarifying the point about the bluetooth - this definitely got buried for me. The case is a good stopgap for improving battery life, but I still think they need to last 10 hours on a single charge to be really useful. For instance, 5 hours won't be enough for a plane trip if you include the time it takes to get to the airport/arrive at your destination. If they can just last a little bit longer, I'd be more on board with the change.
