Just had a quick listen to the 1000X and the QC35 at the store. Didn't have enough time to test them thoroughly so it was done very quickly - same goes for all the features both headphones posses.
Thanks for sharing your comparison of the Sony and the Bose.
Actually I was comparing them as well, just some days ago, but I came to a different conclusion.
I've tried the Sony in two different stores, but have to mention that they both weren't out of the box, but have been on display for some time already.
I paired them (both times) with my Nexus 6P and had the chance to test them with the set-up I normally use and with the music I listen too (Foo Fighters - Learn to Fly; Florence & the Machine -Shake it out; Creed,...).
As I've been follwoing this thread for some time, my expectation were rather high, but I have to admit I was rather disappointed.
The Sony sounded, I don't know, not right - it wasn't affected by the clicking in the left earpiece, but the music at 50% volume was very blurry and the bass didn't sound right either.
My wife tried them on as well, and she didn't like what she heard either.
The Bose QC35 on the other hand sounded way better, quite clear, the bass not too exicting though, but altogether better than the Sony.
This came as a surprise to me, as, after reading here on both the Bose and the Sony, I expected the results to be different.
It might be that the Sonys on display weren't working as they should, but having the same not too good experience in two different stores made me decide against the Sony headphones (for now).
