Quick question about B747 Global First

First off apologies to the search gods, I couldn't find the answer in the threads...

We are off to HKG on the 30th in global first (SFO-HKG) and coming back (HKG-ORD). Has anyone been on recently and seen what kind of headphones they are supplying for the flight? Is it worth borrowing a pair of old Bose headphones for the trip or are the ones provided active noise canceling?

Thanks!
Scott
