Re: Noise Cancelling 700 Firmware Update - Buzzing followed by Headphone Reboot

@Wayne_Mwill there be any kind of notification / statement when a fix is released for this issue? Automatic updates over the app don't work (as my headphones won't connect to my phone properly) and checking manually everyday is kind of annoying...

@bidzej We will definitely post on the Community if and when there is a fix for rebooting when the firmware conflicts with a a 3rd party application. That said, right now I don't have any information or timelines as to when a release would be made available.

 

You may want to subscribe to this thread (done so under Forum Options above the posts) and that should notify you when there are new posts.

 

Hope this helps!

Re: Noise Cancelling 700 Firmware Update - Buzzing followed by Headphone Reboot

Alright, so after a few frustrating months and two warranty replacements I seem to have been able to finally fix this issue, and have also been able to fix it for a colleague who was having the exact same issue.

 

From reading all accounts of this issue it only exists when the NC700s are connected to an Android device. This was present when connected to my Pixel 5, and also on my colleagues Samsung S10

It seems for both of us (and a few other users I found in a reddit post linked below) the issue completely dissapeared after we uninstalled any other apps that managed third party bluetooth devices. For me the issue was resolved immediately after uninstalling the Ultimate Ears BOOM app, and for my colleague the issue was resolved after he uninstalled Sony Headphones Connect app.

I know this sounds entirely crazy, and not any troubleshooting resolution I would have expected. But it seems to have been the case for a few users and I've been able to replicate the fix on two devices. Seems like it doesn't have anything to do with the headhones per se, but it is an android/app compatibility issue.

Hope this helps at least some of you as I know how infinitely frustrating this issue is. I'm now living in buzz free bliss!

The only app I have that may attempt to manage the devices is Spotify - and I am not uninstalling that...

Re: Noise Cancelling 700 Firmware Update - Buzzing followed by Headphone Reboot

If you have a Samsung device you do not need to uninstall any of the apps that manage third-party Bluetooth devices. Instead, you can place these apps into a deep sleep mode under the 'Background Usage Limits' menu which is accessed through the 'Battery and Device Care' menu. This will prevent the apps from running unless you specifically open them, which in most cases means you probably won't be wearing your Bose headphones. You need to then restart your phone OR manually force close each of the apps you put to sleep. You can force close an app on Samsung devices by long pressing on the app and then navigating into its settings (info icon) and then pressing 'Force Stop'.

 

Thanks to everyone for your help on this situation and for leading me to this resolution. I was getting very fed up with my headphones. This method instantly fixed the constant restarting of my headphones. I have always had the Ultimate ears app on my phone but I use it rarely, which means Samsung automatically put this app into a deep sleep after it had been unused for some period of time. This explains why I was able to use my headphones error-free for long periods of time and then they would break for some period of time before coming right again.

 

I hope this helps others!

 

UPDATE #1:  Steps to reproduce on Samsung:

  1. Navigate to Settings > Battery and device care > Battery > Background usage limits > Deep sleeping apps
  2. Place the relevant apps into deep sleep (e.g. UE Megaboom app or MOJIETU)
  3. Manually force close each of the deep sleeping apps (accessed through Settings > Apps)
    OR
    Restart your phone
  4. As a good measure also force stop the Bose app if you did not restart your phone

If the problem persists it is likely that you may have missed an app on step 2.

Buzz and restart

I have had these headphones for over a year so unfortunately the warranty has run out because I was hoping the issue would get resolved with software updates considering bose is not only expensive but known for their quality headphones. I got it as a gift in may of 2020 as a graduation gift so I felt bad about mentioning an issue with such an expensive pair of headphones. But this connectivity issue where it buzzes and restarts has been happening since the day I got it, I honestly didn't even use them for about 6 months because it was so frustrating. Bose should be embarrassed that such an expensive pair of headphones has so many issues. It seems like I'm not the only one with this issue, and I can't get anything back from it due to the 1 year warranty, but I hope that other people with this issue take it up sooner than I did so they can get their money back from such a disappointing pair of $380 pair of headphones.

Re: Noise Cancelling 700 Firmware Update - Buzzing followed by Headphone Reboot

Yebo!!! After weeks of despair and searching several threads on this forum, your solution has worked for me! I had a bluetooth car audio app installed and I have put it in deep slepp as you instructed, restarted my phone and it is now finally working! I was almost giving up and returning my headphones.... Thank you so much @Dan! Bose team please spread the word, because this might be the solution for kost of the people. And please try to figure out a way to solve this incompatibility once and for all. @bidzej @gregojor please check this solution, I believe it will probably work for you as well

Re: Noise Cancelling 700 Firmware Update - Buzzing followed by Headphone Reboot

Glad to hear it @Cristina M!! Given Bose's reluctancy to fixing this bug in the firmware, I hope this solution will work for the majority of users out there.

 

I'm sure other phone brands will have similar power management features that prevent apps from auto-opening in the background. Most phones these days have some sort of battery optimisation settings that can be adjusted. For example, I know that some Oneplus phones have an 'App Auto-Launch' menu that controls whether specific apps are allowed to start in the background.

Re: Noise Cancelling 700 Firmware Update - Buzzing followed by Headphone Reboot

awww yisssss!
I have given it another try. Here is what seems to be working for me (at least for now):

- Bose Music app unistalled

- MOJIETU app (used to manage an FM transmitter for my car) put to deep sleep, just in case. I don't need this app to be running in background anyway.

- disabled Spotify Connect in background (in Spotify's own settings menu)

Re: Noise Cancelling 700 Firmware Update - Buzzing followed by Headphone Reboot

@bidzej yes MOJIETU was the app I also needed to put to deep sleep! And I also uninstalled Bose app for now. Glad it also worked for you! Now I see that I am having a bit of a hard time to connect my radio car again, but with time I will sort it out.
