Ced Yuen posted a great review of the sone to be released Sony MDR-1000x noise cancelling bluetooth headphone over on Trusted Reviews. This is the third review where the reviewer has stated that the noise cancelling is at least as good as the Bose-QC35. Looks like Sony has a winner here. The driver is based on the MDR-1a which is also what the BT MDR-1ABT uses. Which, by the way, I own and love. Unfortunately, the 1ABT isn’t built for isolation so I can’t wait for the 1000x.
Light and comfortable, Excellent noise-cancelation, Superb sound quality, Adjustable ANC level, Excellent mic for calls, Long battery life
There’s a knack to the touch controls
