Re: Firmware 4.5.2 QC35 ii

@glozanomoran 

Here's an update on the issue that involves the inability to see the three vertical dots in one of your posts unless you hit reply to yourself.  I have been working this issue separately with a Bose group outside this forum in conjunction with the use of the Firefox browser.  I can not speak at this point for other browsers.

1. We have determined that the three vertical dots will appear if you run Firefox in "Safe" mode (which has nothing to do with Windows safe mode).  In Firefox you do a "Help", then "Restart With Add-ons Disabled" and then "Restart".
2. So that would suggest that it has something to do with either the add-ons, extensions, or the customization (I have a userchrome.css file to put the tabs below the toolbars).

That is where we currently stand in the testing.  Once we figure out the exact cause Bose will decide what to do next.

Re: Bose QC 35 ii firmware 4.5.2

I am probably the newest victim of Bose scheme. I did the update this weekend (19/10/2019). 

Puzzles me why this company is still pushing this infamous firmware even after thousands of users being affected by it. 

maybe the allegations of “demoting” qc35 ii in favor of 700 aren’t that far from the truth after all.

Re: Bose QC 35 ii firmware 4.5.2

@Renatz from which version did you upgrade? Looking on some YouTube videos on this topic it looks like the issue appeared with 4.*

Re: Bose QC 35 ii firmware 4.5.2

The rest of the internet seems to have this issue as well. I recommend not updating.

 

Bose, can you please verify this with your QA team? Seems to be a pretty big regression since the primary functionality of our QC35 ii headphones is to provide exceptional noise cancellation.

Re: Bose QC 35 ii firmware 4.5.2

Just another person confirming that downgrading to 2.x.x fixed the issue for me completely.

Re: Bose QC 35 ii firmware 4.5.2

How exactly did you downgrade because I don't get to see this option on the BTU website:

Re: Bose QC 35 ii firmware 4.5.2

Bose made changes in their update tool, so they close the door for downgrading. Newer solutions you can find in google, but its become harder and harder, i would say only for very advanced users.

Re: Firmware 4.5.2 QC35 ii

If this whole thing is not a scam I don't know what is. This thread is 4 months old and you still can't fix a minor bug but somehow you were able to code one of the best ANC systems in the world. I am so glad I was able to return my qc35 product and get my money back. Going to buy Sony next week. Good luck with your damage control Bose.

Re: Firmware 4.5.2 QC35 ii

Relax guys, just rolled back to 3.1.8 and difference is almost non. I think there is two explanations:

1. Most of us get used to ANC effect, so degradation its just imagination;

2. There is some hidden part of the FW, that can not be changed by downgrading.

 

Second can be true, because there is tests in YouTube made on pro sound equipment that show degradation in exact numbers.
