I'm on the A330 and we use Sennheiser headsets. Airbus have a different plug to standard headsets. Looks like an XLR jack(for the musicians).
I use these headsets for the departure and arrival phases but after headsets off in the cruise, i have a set of custom earplugs with a 25db(I think) filter. Keeps the high pitch wind noise out but allows voices to be heard clearly through the speaker and I use the hand mic.
Seems to be the best of both worlds for me.
