I puchased these in Singapore and flying back to Australia found that they place considerable pressure on your ears. After the 8 hour trip [thats 8 hours of use from new], they where stored away. 6 months later I dusted them off to preapre for another trip and what do you know the headband broke, they are now useless
Overall I could not recommend to anyone to purchase these, they are very uncomfortable, noise cancellation is average, and not robust.
I'll be packing my old Sony noise cancelling headpones, there still good after 6 years.
