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

Hello everyone, I just joined the forum to comment on the matter. I purchased mine last year in March from Amazon UK. Knowing the Bose QCII fiasco about the noise cancelling issues after updating, I decided not to update my 700's since I took them out of the box, same goes for my QC earbuds, no updates at all.

 

However, I just experienced this situation yesterday (Feb 02 2021) just after I updated my computer to the latest firmware (a Mac mini 2018 - macOS 11.2 Big Sur). Normally, I have them connected to my phone, a Pixel 5, and the computer at the same time. Before the Pixel 5, I have them connected to a Pixel 2. But yesterday morning I turned my headphones on and then a loud noise came out from both ear-cups, just after the voice prompt announcing the battery, so I decided to turn them off after they restarted automatically and perform a reset, the one where you plug it and hold the bluetooth button for like 2 secs or so, nothing happened and I could not turn them on for like 5 min, then after me pressing the ON button for a while, they decided to start again with the usual voice prompt, but this time just after announcing that it was connected to both my devices, the buzzing noise came again and restarted the headphones.

 

So I turned them off again, and waited a couple of minutes, maybe 3-4 mins, turned them on and the usual voice prompt announcing the battery and the connected devices without any issue at all. I spent around 8 to 9 hours with them on and no issue whatsoever.

 

But the again the same thing happened today, like 30 min ago, just after me using them for like 1.5 hours I took my dog for a small walk so I turned them off and came back after like 10-15 min and turned them on and just before the voice prompt announced the battery level, the same buzzing but this time just from the left ear-cup in a very low volume, audible enough to be honest. So again I did the same, turned off and on without any issues at all as I am using them right now while typing this.

 

To be honest, I have no idea what is the problem with them, as yes it is scary that this is happening and yes, I do not want to send them back under warranty and get a new pair which would potentially have more issues. So after running some test turning them on and off several times there is no issue at all, at least right now. The only thing that I noticed is that the computer did a weird noise, like a notification sound but distorted the same day after I updated the computer and stopped the every bluetooth device from working (keyboard, trackpad and headphones) for like 5-6 min. After that I carried on until yesterday when the buzzing started.

 

I know that this is an ongoing situation, but hopefully someone has a clue of what is happening as I am running the factory firmware without updating or opening the app while connected to the headphones, other than naming my device and set some configurations like 'voice level when calling' but I did this with my phone on airplane mode and just the bluetooth on to prevent any update from downloading.

 

Here are some extra details just in case if someone is interested and find it helpful somehow. Also, I should mentioned that I have never had any problems at all since I got them and I take care a lot of care for my stuff, and I only dropped them once back in October 2020.

Re: Bose 700 - Makes a loud buzz noise and reboots

2021 and 3 replacement later and here we still f***g are, aaarrrgh.

What a trash company. How can you not reproduce it consistently while I had 3 headphones replacements consistently not working for more than a year now? Boot loop and buzzing, and it always happens at the worst time, like in the middle of an important call, or when I'm in a rush and needing to have music on.

 

I wanted to buy earbuds for workout and headphones for my girlfriend. A year ago I would have chosen Bose, but man, you guys actually suck. A headphone produced in Uganda is more useful than this ANC 700 crap. I'm recommending everybody I know off Bose, and that carries weight from someone who's used Bose for 3+ years and is into high end earpieces.

 

I was trying to be very patient and gave Bose the benefit of doubts, but now just a "oopsie sorry, here's a form to fill" after more than a year of reporting?

Re: Bose 700 - Makes a loud buzz noise and reboots

I filled out the form, but wow Bose, I started this thread in May 2020. I find it difficult to believe that you can't replicate this issue in your lab after all this time and numerous customers reporting the issue. 

 

I sent my problematic 1.5.x headphones back to Bose HQ last summer for replacement with the thought that they would be used in your lab. Heck, I'm close enough to Framingham for a visit to help your lab engineers out if it weren't for the pandemic. My replacement headphones are (probably) at 1.3.x and working flawlessly. I'm not using the Music app and risking a chance of an unwanted FW update but the two FW releases beyond 1.3.x both resulted in the buzz/reboot loop.

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

Hi, i am having the exact same problem and I've only had these headphones for a year. All issues and steps have been taken exactly the same way as the original poster explained. I am also wondering what could be done about this since I really have enjoyed these headphones.

Re: Bose 700 - Makes a loud buzz noise and reboots

I have the exact same or at least extremely similar issue as the original post on this thread.

When I turn on the headphones the voice in the headphones starts speaking, then I hear a loud buzzing sound, and then the headphones reboot. In some cases it will do this a few times before finally operating normally.

In the end the headphones always seem to end up operating normally, but the buzz/reboot sequence is very disturbing. My headphones tarted doing this about 6 months ago. Then after a period this went away, but recently it has restarted so I thought I'd post about it.

I use my headphones mostly for conference call, not so much for listening to music.

I typically have them set up to connect to my phone (Pixel 5) and laptop (Macbook Pro) at the same time. 

The typical boot sequence would be something like this

1 - Press power button on headphone

2 - Voice in headphone says" ... Connected to ..."

3 - Headphone emits loud buzzing noise

4 - Headphone seems to reboot (I hear the boot up tune again)

5 - Voice in headphone says "... Connected to Pixel 5 and Macbook Pro" (It uses the bluetooth device names really)

6 - Everything is fine.

 

Note I checked the Bose Music app and I am running the latest firmware: 1.8.2-11524+e0f7590

I am going to also fill the form I just saw was mentioned in one of the posts earlier

 

Given at some point this disappeared, I am wondering if there is some sort of factory reset I could do to make this go away, or how I should proceed to get rid of this behaviour as it is extremely annoying.

Re: Bose 700 - Makes a loud buzz noise and reboots

Hello, 

 

I have the same problem. The headset came with fw version 1.1.4 and everything worked fine but then the app updated the fw to 1.8.2 and the problems begun again. I want to point out that this is a replacement, the first headset did exactly the same. While connected only to my laptop that has bluetooth 4, everything works fine. However the moment i connect them to my Samsung S20 Ultra that has bluetooth 5.0 the freeze/restart cycle keeps going.

 

I tryed to fill out the form above but it seems to be closed. Bose, if I can help you with any info with the situation let me know, I really would like to be able to use the NC 700.

 

Thanks,
