[@banana_boi7649]

Well that sucks. I have own a Bose q35(I not II), and I got a firmware update a couple of months back. I realised right away that the noise cancelling wasn’t as powerful as when I first got them. The reason I got them(used) was because of the superior *noise cancelling*, and they got rid of that after the firmware update. It’s wasn’t worth the price anymore, so I’m giving them to my dad.

[@Arzo001]

Nice!! Thank you!! Please make a downgrading video to older firmware that works! Many thanks to you, great job!!

[@t.quante8657]

finally i found something that proves my doubts, thank you sir,recently i bought a bose qc45, it‘s not on market anymore but i found one on amazon, i loved the performance of anc at first, but next day it was updated itself( background updates) and then voila, there is no difference between the quiet or aware modes, it is just company greed as apple did such a thing couple years ago for older mobiles, i hate this era, greetings from turkey

[@shunpillay]

Software and firmware mistakes happen. It's natural. No biggie. However if Bose does not release another update to fix this one, then I think we have a serious problem. Thank you for this video. I appreciate the warning, and will not be updating my set.

[@JohnCiaccio]

Everyone is talking about the timing of the "mistake"..

[@bpjbp]

This update has been out for little more than a month now. Bose has only said that they didn't change anything with ANC in the firmware, and that they can't duplicate the issue. They have requested certain users to send in their "broken" headphones for testing. As of 1-2 weeks ago, they said that they received only one (1) from users (even though many users had said that they sent in theirs) and that it doesn't have an issue even though the former owner swears that it does. Bose has also stop supporting firmware downgrade. They remove any comment that references any other website. So if you post a link to this video, Bose will remove it. Bose has been completely quiet since. They have not taken down the 4.5.2 firmware. In fact, the Connect App keeps pushing it. Yet the reports of ANC degradation keep pouring in. Even if Bose truly didn't deliberately alter ANC, their method of dealing with this has been complete crap.

[@D-av]

Well... 5 months later and guess what: nothing happened. No new firmware, that sums it up, right?

[@MelroyvandenBerg]

@@JohnCiaccio yea.. valid point.. with this 700 release. hmmm >

[@visissium]

For those watching in present times, the offending firmware was 4.5.2. The later released 4.8.1 seems like a significant improvement according to several forums so I would imagine this is fixed now.

[@morganahmed6245]

I have the same new version but i dont know if its better or not

[@64Gianfar]

Reverting to from firmware version 4.5.2 to 3.1.8 it's blatantly obvious that the ANC is reduced for some frequencies. What I personally think is that BOSE wants to reduce the "Cabin Pressure" effect as Sony and many others do not have this issue, however to achieve this it also impacts the ANC negatively, hence why BOSE wont admit to any issue. Voices with ANC on high with 4.5.2 is about the same as low with 3.1.8. same source, same environment. I bought the QC35 II for the ANC, BOSE reducing the effectiveness does not impress for one second. What's worse BOSE outright denies any issue, however directly comparing the firmware versions the ANC is clearly reduced, same a DMS illustrates. BOSE could have avoided all this issue by simply allowing it's users to choose the firmware version, personally I don't reward companies for such behaviour so next ANC headphones wont be BOSE.

[@mausyyy85]

Exactly let buyers choose, or built in an extra `Preset` for this Cabin Pressure issue. I agree with you Raven

Anc did not fix..fw 4.8.1

[@David-Field.Stuff01]

I hadnt updated my qc35 II firmware since mid 2019 but accidentally chose to update it last week after not having used the headphones for several months. Guess what? The active noise cancelling effect is now weaker on bluetooth and if using the headphones without music as ear defenders, but more disturbing is the fact that the ANC controller button doesn't work at all on the wired connection and the ANC effect seems to be fixed in the middle of its 3 positions. If i remove the wired connector all 3 levels of ANC are returned, put it in and 2 of them vanish. How do i go back to the previous update?

[@nikolailu]

Apparently they still haven't fixed the problem (I just checked the bose forum thread for this problem (its currently at 212 pages with new threads and complaints as recent as a few hours ago). I think it's pretty clear by now that Bose intentionally killed the quality of QC35ii noise cancelling to try and force people to move to 700, as in their official thread they still don't give a shit and just ignore people's complaints. What do you think? You have any new info on this subject? I'm about to buy QC35ii (but to make sure i dont upgrade it)

The ANC degradation affects both the QC 35 II and the QC 35 I

[@andrecarvalho8679]

So the 3.0.3 on series I is the same firmware as the 4.5.2 of series II?

[@64Gianfar]

My QC35 II auto updated thx to BOSE's app, the ANC is now weaker plain and simple. I'll return them to BOSE for repair or replacement, the change was very obvious to me as I used the headphones on an international flight, on arrival they updated. ANC is now clearly different, nor for the better. Due to the sudden change I looked on BOSE's own community forums and there's a good deal of complaint with little action from BOSE...

[@musicalmind9591]

Hi DMS! I see this video is made in July, I'm on 4.5.2 currently, should I downgrade to 3.8.1 or they fixed this in the mean time. Please advise, thank you!

@DMS does 4.8.1 fix this issue?

[@Alex55555]

It doesn't seem like a mistake. I mean it can't be. It's not like releasing an app update for android phone, for which there are a lot of variations in the os version and hardwares, so it's difficult to test all possibilities. This is one single headphone line we are talking about!!! Don't tell me they didn't even test it before releasing the update, that would be even more worrisome. What kind of engineering is that?!

[@radusebastianionita803]

I am just wondering if this is proof enough that could stand in court? Could Bose be covered in this scenario ? We could make a short fund raiser that could collect enough money to get a proper lawyer and bring storm upon their asses. I've checked the official Bose forum, where a newbie asked if he should go for 3.0.3 on QC30, and 5 forum members said: No, it will decrease the ANC, to 80%. The 6'th post was from the forum admin, saying that he encourages the upgrade. The guy did the upgrade, then he came back to the post saying that indeed the ANC was decreased, and asked for help from the mod. The same mod who recommended the update, copy pasted a : "please reset your device" answer . I mean this is a tech company ... how are they still in business ? You can't possibly live off a brand name, without giving decent service. Anyhow, who's up for suing Bose ? I am a QC30 user, flying a lot, from office to office, open space offices, etc ... i feel like ANC was the only part of this product that kept me on-board, but with the recent updates, i'll rather switch brands.

Most real world noise should be closer to brown noise, and the reproduction of subbass below 80 hz is crucial too for ANC. Adding a subwoofer and the result may change further. But it’s interesting about pink noise, theoretically weird if white and brown can hold, where pink’s nature in the middle. A sweet spot to fail? Thanks for the test.

[@chris24hdez]

The 700 might have been worse at noise cancellation in the few weeks leading up to the initial public release. I believe the older models were downgraded to not hurt the sales of the new product with inferior performance on the primary feature. Things i like: flat and faithful audio response with nearly zero distortion. 2-device sync. doesn't hurt after wearing for many hours. Things i don't like: No way to pump up the bass without lowering treble and overall volume. gets hot and sweaty. oils show up on pads and headband. Noise reduction is ruined. microphone voice quality is still terrible. touch controls have eliminated seek/scrub ability. Rattles when walking fast or running.

Hi! Thanks for testing. Did you already received an official reaction from Bose? (aside from their we didn't change anything?) There has been 1000's of posts on Bose its message board.

[@attilab.2818]

Dan hunter It’s good to have a long warranty. I have had 7 pairs of Sony WH-1000XM3 in 3 months. After the 6th replacement I gave up. There is a different between plastic and plastic and also between built qualities. Doesn’t have to be necessary Bose, just mentioned as there is a QC35II at home as well for instant comparison. But I could also bring up the Sennheisers, the Beats Solo Pro , B&O and Bower & Wilkins headphones. Seriously, XM3s have the worst built I’ve ever used. I have had 7 pairs of Sony WH-1000XM3 so we can’t say I had a faulty pair because it’s not the case. The headband and hinges start creaking, squeaking pretty badly, within a week of usage, like a plastic toy for 5 years olds. I used the latest 4.2.2 firmware with them, and never been impressed with the ANC. Not just one, experienced the same problem with the all 7 pairs. The noise cancellating wasn't better than my Bose QC35 IIs or my N700s...wasn't worse either, but nothing special after the other two. However there is one thing I have to mention. The Sony's ANC was completely useless on public transport, especially when travelling on buses. If the bus hits a pot hole or bump, the ANC suddenly goes off for a second, causing heavy distortion to the music and you can also hear the pothole through the headphone, terrible. So the perfect noise cancelling shouldn’t really be used on a crowded, rattling bus, exactly where it’s supposed to be. Also, the adaptive function is so unreliable, useless. The sensitivity is crap. Sometimes changes to transport or walking node while you've been sitting in a cafe shop for half an hour and didn't move at all. Or just stuck in walking mode even you sat down already and you've been like that for 10-15 minutes. First thing first to turn off this feature as soon as the app got installed. For this pricetag these issues are just simply unacceptable. Not the mention the terrible call quality. If you don’t have any problem with yours it’s good, enjoy them. After the Bose and Sony flagships now I have the Nuraphones. These headphones blow them away. It’s worth to check them out if you like to lose yourself to the music. A very unique, immersive experience.

[@derekw6811]

I returned a new pair of QC35ii because of this update. I picked up a pair of 700s instead and they aren’t all that impressive.

Happy to know if you have any suggestions, but for the moment I have to take ANC. My favourite is actually PXC550, though only very moderate ANC, enough to reduce noise rumbles, maintain music tonality (esp bass that washed out in passive isolation) and strike a balance in sound quality, and workable mic. That’s why I always ask myself how much ANC is indeed enough? I have WH-1000XM3, QC35II, HD1, Microsoft, used to have B&W PX, and PXC550 is always my pick going out.

Bose has a long tradition in fooling customers. Selling them (surround) sound systems for hundreds and thousands of bucks consisting if cheap and shitty plastic worth a few bucks only. With today's social media power they shouldn't dare to repeat such evil behaviour.

[@DMS3TV]

Right! And something as common as ANC shouldn't be tampered with because that's most of what keeps them on the market now especially with all the competition!

Bose is the Apple of headphones

Apple has overpriced headphones as well. The Dre beats remember.

@@liadsagi3 Bose's support forum has hundreds of complaints. I could see a few complaints being "placebo". But hundreds?

typical anti consumer behavior

Still running 2.0.1 on my QC35ii. No way in hell ill be updating with all of the information out there suggesting that newer firmware version break ANC. Wake up Bose and address this. You can only deny for so long.
