Re: Options to downgrade

This is so frustrating as the problem hasn't been solved yet and I still feel that the upgrade didn't change anything it only made the noise cancelling worst. Why would I recommend someone to buy such an expensive headset if they will hear the person sitting 200m away from them.

1. Bose has not taken ownership of this through any statements here.  They continue to claim the most recent firmware version had no impact on ANC

2. Even if they did, they would not tell us they did and we would not know anything until the next firmware update and we as customers tested the ANC for changes

3. Firmware changes don't happen very often for established/'stable' products.  They just upgraded the firmware in the beginning of March.  I am guessing we won't see another change for some number of months - perhaps sometime this summer.

4. There is no going backwards with firmware upgrades and Bose has no current intention of changing that.

Re: Options to downgrade

Just a small input at my end :

After a lot of reserach I finally found a way to downgrade from 4.5.2 to 3.1.8 !

 

After checking (and switching between 4.5.2 and 3.1.8) I noticed that the ANC performs better (no noticable difference between high and low on 4.5.2, but clearly audible on 3.1.8) and this white noise (like distant rain) is completely gone .

So I don't know whats going on with Bose (most people would say that with the new headset coming out they'll decrease the quality of the 'old' versions) but quite disappointed...

For my part, I finaly left my QC35ii on 3.1.8 and deleted the Bose Connect app on my phone.

This way, the ONLY way to update them is by doing it via wire.

Just a thank you to Bose that they do not allow downgrade of your purchased product.

I'll stick with this version unless I hear something good about a new one.
As they say "If everything works, why update ?"

Re: Options to downgrade

"Hi Steve, 

 

Thank you for reaching out and welcome to the community!

 

We do not have the option to roll back firmware as the firmware updates often contain bug fixes which resolve issues that have been reported with previous firmware versions. 

 

We feel that by downgrading the firmware, previous issues which were deemed resolved will begin to resurface. 

 

I hope this helps and have a great day!

Re: Options to downgrade

@hockysaI thought when the 4.5.2 study came out (I have not read it recently), Bose was offering a temporary opportunity to downgrade.
