well - i don't think theyre great for blocking voices.
the sonys work better with nc
my suggestion is to buy both of them and see which one you end up keeping.
QC35 > 1000x
comfort - feel lighter and the 1000x seem to be made for a bigger head
mobile app - switching between computer and mobile phones
1000x . qc35
music quality much much better
noise cancellation far superior - blocks most voices
touch controls - while finicky more usable than the qc35s
build quality - great quality - the qc35s feel like a toy
Like you said if you can try both then do so. I'd have to disagree with most of what you have said, but that shows we are all different.
First off, I think the Sony's are only better sound wise when used with LDAC and decent quality FLACS. I have. Sony NW 25 which is why I got the 1000's the sound quality was better than any Bluetooth connection so yep it beat the Bose, but connecting the player was a bit hit and miss sometimes, surprisingly! Anyway, the Bose paired with good 320k rips on an iPhone also sounded good. I actually found the base on the 1000's to be lacking, almost anaemic. I prefer the Bose, it's fuller but remains tight enough at the bottom end to impress, when I use the Bose with the cable, and my a25 then they take on a different sound and sound much better than with Bluetooth. So I guess it varies on the source and the file quality as to sound experience!
RE NC, they are both so close I don't believe it's much of a contest, the Bose pip the Sony's for me because they just work, I never have to recalibrate the Bose and had no issues with popping and pressure which I did with the Sony's
Touch controls, nah, volume and skipping was fine, but pausing was a right pain, having to tap dead centre when you can see was a real pain. The buttons on the Bose work 100% of the time, period!
Build quality for me is no contest at all. I had the 1000's for a week, on day one there was a knocking noise in the left ear cup, if you tilted your head or opened and closed your mouth it was there, by the end of the week I could hear it when walking. It was amplified because of the fact the NC is great. I went to replace them and the new pair out of the box had the same issue. It was faint, but I figured as with the first pair it would get worse. The Sony shop offered to send them to there repair shop and see if they could figure out what the problem was. But I went with a refund
Also call quality was basically terrible with the 1000's compared to the Bose, seriously not even close. And connectivity is way better with the Bose, easily connects to 2 devices, the MDR's were trickier and many people don't seem to get it to work.
So for me the Bose pip the 1000's. I may would have probably stuck with the 1000's for the LDAC had they actually not made noises when I moved, but read the forums and people are complaining about knocking and creaking with the Sony's, I've not had any issues with now 2 pairs of Bose. Also I reckon the Sony's will look a lot worse in a year or 2. I had a pair of MDR 1BT's a year back, the 'pleather' wore off both ear cups and looked horrible in the end!
So yes, have a good play with both and see what you reckon.
