I own the new version of these headphones with AZ series and Bose recommends to update the firmware so I thought since they are a day old if something goes sideways I can return them :-) so I took the risk. As you mentioned, indeed it is a very subjective matter and hence I just wanted to know what to expect from these headphones like if they aren't meant to cancel out what others are talking then fair enough I won't complain about that. In one of our rooms, there is a window AC that creates humming sound (perhaps similar to what you mentioned). I gotta say it canceled it out. My questions to you are 1. Do you, along with the music, also hear the amplified wind sound in your headphones when you are in a windy condition? 2. Do you hear nearby people talking when you have headphones on when ANC is on (with and without music)? 3. How about Bluetooth connectivity, do you also face a similar issue as mine? Your answers will greatly help me in knowing and setting the right expectation for the headphones that I own. Your time and efforts are highly appreciated. Best Regards, Rahul Sharma Try Using the low noise canclling setting on a windy day, High isnt design for wind and will amplify, low completly removes this issue. If you check the manual on page 21, you will see this:

Agreed. In my case, I had a brand new Bose QC 35 II which shipped with the firmware 4.1.3. On the way back home from buying the headphone, I tried it out and was amazed at the noise cancelling, it completely silenced the car I was in. I felt very noticable pressure in my ears from the noise cancelling but was willing to live with that in place of great noise cancelling. On that same time however, I noticed on my phone the 4.3.6 firmware update in which I updated to. I was using the headphones while the update was doing its thing. After the update there is now no pressure from noise cancelling however I feel that the noise cancelling is inferrior as I can now hear the car and as you said @NeB, there is no diffrence between high and low anc. I did notice a diffrence in one instance on a windy day where on high I would hear interference from the wind but on low this was eliminated. Now I shrugged it off as I only used the original firmware for about an hour before the new firmware 4.3.6 and thought maybe its just my mind and other posts are about older firmware versions. But your post, increasingly raised my suspicion on this issue. Almost makes me think that the new update was meant to reduce the pressure on the ears due to ANC as many complained on the internet which results at a cost of ANC performance but I maybe wrong. My headphones were manufactured in 19 November 2018. Now when I get time, I will visit stores which have the Bose QC35 II in display and comparing it to mine to see if my unit does have worse ANC and will also give me proof.
