Bose QC 35 II & 2018 MacBook Pro - mono audio and crackle over bluetooth

Brand new out-of-the-box Bose QC 35 II and a few months old 2018 MacBook Pro.

 

I can connect to the laptop and hear sound but the sound is in mono and I hear crackles. Things I've done:

  • Reboot laptop
  • Reboot headphones using 30/5/60 method
  • Update Bose firmware using updater to latest version as of this writing.

 

I've owned the QC15, QC25 and now these. Should I return this pair, exchange? Buy the Sony's instead?

Figured out my MacBook Pro was making the connection to the QC35 II's use SCO codec instead of AAC or AptX. So I did the thing where you use Xcode's Bluetooth Explorer Audio tool to force use of AptX and enable AAC. Rebooted and all that.

 

Still using SCO. Still a problem. This is super frustrating. I called Bose. No help. They sell these things in Apple Stores and they don't work with Apple's latest laptops & OS.

I guess I'm returning it.

Sometimes I get this Bose headphones to work in Stereo on my Mac when I swith the audio input to internal microfon instead Bose.

But this works only sometimes. Its very frustrating to see such issues on such an expensive product. If I would have known it I would never have bought Bose.

 

If you have any fix for this, let me know.

It might be worth checking the balance is not set all the way over to Left or Right. This happened to me..

 

1. Click on the speaker icon at the top of the screen.. 

2. Go to "Sound Preferences..."

3. Check the Balance
