Bose QC 35 one side doesnt work on macbook Monterey 12.01 while it works on iphone

Partially repeat previous advice but with differences.

Go to Sound settings on your Macbook, select "Input" (where placed available mics), and you could see that Bose QC 35 II is chosen as input (and works as a device for calling and so on). If you change the input to a Mac microphone - QC 35 II will work in normal mode.

I used this hint earlier, but from Monterey OS sometimes it doesn't work

How bizarre!

Same issue here - MBP 16", 2019, macOS Monterey 12.0.1 with QC35 II.

Was happily using them for ages and do not remember exactly when exactly this started to be happening - upgrade to Monterey perhaps?

Funny thing is, that very first thing I did, as others were advising, was a firmware upgrade on QC but this did nothing to improve.

Then someone mentioned balance all the way to the right in sound settings - bingo! I do not believe firmware update was necessary at all BUT what is really odd is that EVERY single time I change the volume using macOS volume slider, balance goes back all the way to the right, making sound to be coming out of the right hand can only (this does not apply if I change the volume manually using volume buttons on QC35 themselves).

Not sure if this is something to be fixed by Apple or this is specific to Bose but the latest upgrade to 4.8.1 did nothing for me to fix the issue.

Cheers.

Updating to Monterey 12.2 created this balance issue for me, but changing the balance setting in System Preferences > Sound fixed it for me (the slider was all the way to the left).

Had this issue, checked and found that just as you said, the balance had somehow (I definitely didn't do it!) migrated all the way to the right.

This solved the problem for me! For some reason the slider was all the way left but I have never touched that slider before. Thank you :)

I was having the same issue, try this fix: go to Sound settings on your Macbook, select your device from the list, and double check the "Balance" setting. It might be moved all the way to the right or left. Just pull the slider back to the center. Hope this helps

I have the balance issue as well. It is happening pretty often.

But I have a weird issue too, it connects and disconnects randomly, I checked the firmware, and it is up to date. I am using the Bose QuietComfort 35, so the latest firmware is 3.0.3.

It is random but happens more frequently when I am using Zoom/Meet/Slack. This leads me to think that it is a software issue in the macOS. I work with two Macbooks, a 15-inch, 2018 model and another 2020, 16-inch 2019 model. Both are running on the macOS Monterey.

Perhaps it is a different issue because there are some people mentioning the Bose QC 35 II.

I have not found any solution so far.

I'm using QC35II since 2018 (I guess), and an earlier version of OS hasn't this problem (from MPB15 2017). But from 2020 (I don't remember the exact version OS) and Monterey (at the moment I'm using M1 Air) - it's a regular problem and old hints don't work correctly. Definitely, it's a software or hardware+software bug because on iPhone all work perfectly.

Hi there,

I'm having the same issue I heard a strange sound and now only one side is working (works fine on iPhone not on MacBook), but I do not see any updates in the mobile app (it says my product is up to date). Are you on 4.8.1 (app version 17.0)?

Thanks!

Same issue here. The sound works fine on my iPhone 11 but on my 2019 Intel Mac running Montery 12.1, sound is only coming from one side of the headphones. My Bose app is up to date (17.0.1) in iOS as well as my firmware version (4.8.1). The app says my product is up to date.

I had this same issue when I finally could connect again (for some reason I also had connecting issues and losing sound while listening) I did the same as jerichokirkley!

Strangely, the connection was working fine again for a while and suddenly today I'm having issues again. The sound is stuttering and I removed the other connections, but it's still happening. Anyone having the same issues?

I was facing the same issue with my Macbook air M1 and my Bose QC 35II. I tried this out and worked for me.

Not sure why this happened as it was working on both last night.

Thanks for the solution though.

This is what worked - thanks
