My flight enjoyment increased exponentially after buying a relatively cheap ANR headset - I didn't realise how tiring white noise can be. I suffered from nausea, strangely, for the first half hour of wearing them but soon got over it. Love 'em and only reluctantly wear PNR headset.
Interestingly, I've had a number of conversations with newbies who whinge about the costs of headsets yet still sport Breitling watches and single bar epaulettes... The cost of both of these should have gone towards a decent headset, IMO.
