Got mine yesterday and took them for a subway ride, the NC is spectacular and without doubt the best sounding NC phones available. Actually, this is the first time I think Im going to add NC cans to my collection, I always ended sending back all previous intents I had with Bose, Parrot, Meelectronics, Beats, Sennheiser, Audiotechnica and even other Sony models... I do a lot of transatlantic traveling but so far I survived with my CIEMS, the thing I never enjoyed with the CIEMS is the changes in cabin pressure plus they are wired, the versatility of this 1000x seems greater while on the road. I will test them next week with busy airports, airplanes and trains.
Stop propagating the creak thing, this is how myths are made... Mine are perfectly fine and it appears that also others are fine too. Im sure it was a bad batch and this doesn't make them bad phones that deserve a bad myth.
