Up until last week I *STILL* had the first gen MDR-1000X. Compared to those these are much lighter to wear & can be adjusted to fit better as well.
The materials are all different, which I appreciate. And the fact I can now be connected to two devices at the same time is worth all the money!
The only drawback so far I have found is the way too short charger cable. I do not have any set up at home where this can work with the headphones so close to the charger itself (space issues). Buying a longer cable will do.
