Re: Firmware 4.5.2 QC35 ii

Thanks @joelirwin 

 

Sure, conjectures abound but Bose could be more transparent about this issue whether it's a small sampling of their user base or not. The fact that there's an absolute deniability of anything wrong with the headsets post FW update, against proven arguments from a great number of users, is a problem. We could debate a conspiracy theory forever- but simply stating that they never changed anything and therefore it isn't broken doesn't seem like at a very minimum, good customer service.

New video from rtings comparing bose 700 to qc35ii, around time 9:20 they mention the firmware update of the qc35ii and that the anc performance did not degrade noticeable. https://youtu.be/w1Gg8_CfGxY

Well, perhaps not.. So re-tried 4.5.2 yesterday again, using them in the train. call it placebo, but I could hear a difference, so after 4.5.2 now back to 3.8.1. Next, just to check if it's just my experience, I've looked up the latest update at Rtings on this test and video.

Surprise... It is still clear that the NC performance of the 4.5.2 is worse than the versions before. :

 

Quote"

Update 08/22/2019: We've re-tested the noise isolation of the Bose QC35 II and the Bose Noise Cancelling Headphones 700 after noticing a flaw in our testing methodology for both headsets. For the QC35II this means that while the 4.5.2 update did reduce a bit the noise cancellation performance of our unit but less than we had initially reported. This has changed the score, and the text has been adjusted to reflect this."

 

For me, the difference is in the amount of noice reduction of voices. On 4.5.2 I clearly hear more sound of voices getting through than on 3.1.8. And, no, I don't expect them to totally fade away. But when it comes to the NC, to me it's the difference having them filtered away enough, or have the feeling to hear them just to loud (so being irritated by them when listening to soft music).

 

So I still wonder when Bose will come out with a fix, not everyone is capable of performing the downgrade.

Re: Firmware 4.5.2 QC35 ii

Agree Jbrugger..

The interesting outtake of the rtings rating is that the QC35-II outperform the 700 on many levels.

I'm further a bit dissapointed by the fact that they summed up the firmware update episode with a one liner mentioning

that the ANC quality actually has dropped (a little, but what is a little?). So at least acklowlegding a difference in quality before and after the update. However, the failed to research and test it. 

 

In this film the difference in quality is tested and clearly shows a difference in ANC sound profile / quality:

Did the recent update from bose make noise cancelling worse? In this video I test that to find out. My social media: https://twitter.com/dms3tv https://Insta...

Re: Firmware 4.5.2 QC35 ii

As i understand, when listening to speech, we're the most sensitive to hearing voice on a frequenscy between 300 to 3000 Hz.

Looking at the graph, the older firmware outperforms the new one on the largest part there, higher pitched voices should be better on the newer firmware, but only for a small part.

It shows there that our feeling on hearing more voices using the new firmware is correct, and 'a little' should be enough, since our hearing is focussed on speech. 

I'm no specialist in this area, but the outcome of the graph and the perception a lot of people have here speak for itself.

This graph was made with 4.3.6 firmware version.

Re: Firmware 4.5.2 QC35 ii

So, I wanted to jump in and share my experience on this too as I have recently upgraded from qc35i to qc35ii and have now experienced actual (not subjective) ANC issue across 4.5.2 and 3.0.3 versions.

I have upgraded or shall I say bose has downgraded the software on both qc headphones in the last 4 weeks. 

It was following the initial firmware update on my original pair of qc35’s that caused me to research whether there is any issue with ANC following the 3.0.3 upgrade.  

 

I contacted bose directly and had a lengthy chat with an extremely helpful tech adviser who talked me through resetting the cans, connecting to my pc to update etc. I was then asked to return them back for further investigation.  Now the customer service interaction was fantastic.

 

Jump forward 2 weeks.

 

I have now received a pair of the qc35ii serial no. ending in AZ that were manufactured June 2019. Out of the box all was great and the ANC was performing back to how it was ( I know this as my daughter plays ps4 in the next room, and I could no longer hear it… Success!  So I thought.

 

When I then connected to the app (ios), I was prompted to update to the latest firmware version (4.5.2) and update the app too.  

 

Now, you’d think I would have learned my lesson,  however, as the software version number was different from the previous update I had performed, I (naively) believed that this was a fix for the original issue.  I hadn't appreciated the series i and ii are running different versions.  

 

So, I updated.

 

20 minutes later after the cans have updated to 4.5.2, I put them on and to my total surprise, ANC in the high setting has degraded on this software update too.....  ( I can now hear my daughter in the next room)

 

The hindsight questions begin to play out in my head, ‘Why didn't you think that this could happen?’. Why didn’t you check online for the series 2 software issues?’ where do I stand now’? etc…

 

Im struggling to believe this is an isolated defect that was not picked up in QA.  I have now in the last month owned 2 different devices with different software updates and have experienced the same degradation in ANC and find it frustrating to think that a premium device at a premium price from a premium company can affect so many people without some form of acknowledged responsibility.

 

Please help fix the problem and restore what were the best ANC device in the world in my opinion.

Have you tried to contact Bose again after this incident?
