Hi DrWhoIs,

Cabin pressure means when the headphone produces a reversed noise cancellation 'sound'

with a certain frequencey band that produces the same feeling when you take off in an airplane.

When you have to pop your ears..  With the earlier Bose headphones this feeling was very prevelent.

It was somewhat reduced, as most people have to get used to the feeling of having pressure on their ears.

However, a light version of the cabin pressure feeling seems to produce the best active noise cancellation,

esspecially the mid high to high frenquencies...

If any tech people out there want to add or improve plz do:)

I purchased my headset 2 days ago and updated to the latest software and instantly saw a difference in the quality of the noise cancellation

Re: Firmware 4.5.2 QC35 ii

From the 100+ pages on this thread, I am assuming already that:

 

1) Bose will not admit fault and hope that we'll go away

2) There's no planned fix for this. They want us to buy the 700s (as if...)

3) Bose isn't worried about the damage to its reputation

4) The purchase I made of the QC35II is deemed a loss.

 

As for me, I pledge that the QC 35II was my last purchase of the Bose brand.

Friendly reminder that it’s been 2 full months since Bose was notified of this issue as has completely ignored our request to allow users to downgrade back the firmware.

Re: Firmware 4.5.2 QC35 ii

Hi Guys,

I just received my Q35 ll in the mail today and by pure luck found the thread with all the firmware issues, my question is simple. Should I return them and get a Sony or just don’t update the firmware? Thank you
