had my BT headphones go dead halfway through a flight. Options..? Stare out the window My bluetooth headphones give around 3 hours of use from 15 minutes of charging. Apple iPods supposedly give 1 hour of use after 5 minutes of charge. Annoying to have it happen in the middle of a flight, but it doesn't mean I have to forgo music for the rest of the flight.
