Questions about Quiet Comfort Ultra

Nope. USB-C exclusively.

I don't have one with me. Unless the bracket is set much too long, I would file a warranty claim.

Absolutely, also offer noise cancelling

This should be adjusted. Thanks for your comment. :)

Ka that works.

Note that the device only works via Bluetooth on the computer. It cannot be used by connecting it via USB.

There is no "ANC off" mode like other headphones have.

However, you can add a custom mode and set the ANC to zero....
