Re: Bose QC 35 ii firmware 4.5.2

Polish customer service refused to replace qc35 to newer 700’s. That’s a big shame

Re: Bose QC 35 ii firmware 4.5.2

Kjwan, are these CQ35I or II? What is the manufacturing date?

Now they send me the 700 series for 50 euro extra.

Not a solution I would take in consideration because sound of 700 is not even close to balanced trebles of QC35II

Re: Bose QC 35 ii firmware 4.5.2

I would like to add that I am having the same issues like all of you on my QC35 Series I!

 

I am experiencing this since the firmware was updated to 3.0.3. Before they were on 2.5.5 and I didnt have any issues.

My QC35 Series I were manufactured on 4th of October 2016.

Re: Bose QC 35 ii firmware 4.5.2

I also updated to current firmware… successfully… Mine were made March 26 2019. with … AZ serial number.

 

So I'm not concerned by this this bug, but I'm a little bit scarred how Bose try to "solve" the issue. They said, in 2 or 3 posts that they are currently investigating the issue but we do not know if they are sure if it is a bug and/or if they want to fix it.

 

Bose should pin a forum post with the procedure to follow by someone affected by the bug. They also should post more often to keep us up to date… if they care about their customers…

That's what most of the reviews say at least.

And there is no guarantee that Bose will keep a efficient ANC with future firmware updates for the 700 series. They can destroy the 700 like the QC35

No. They are not worst. They are different. They sound a little bit "warmer" and the treble are a little bit better in the sense they are no longer "chemical".

 

So it is a personal feeling saying one is better than the other…
