I'm flying upper class SFO-LHR-SFO later this week and have two questions (have never flown Virgin before):

1. Are there power chargers at the seats and if so are they set to accomodate 110V U.S. style power cords from laptop computers etc?
2. If I want to use my BOSE noise-cancelling headphones on the IFE will I heed a special adaptor to be able to get the IFE sound through them?

Thank you in advance!
