QC35 II and Macbook Pro Wired vs Bluetooth Volume Difference

[jtiptonk]

Hi, the playback volume on my QC35II's is much lower when using bluetooth vs the wire when connected to my 2017 Macbook Pro (os 10.15.6). Is this expected? 

- There doesn't seem to be a volume difference when switching between wired and bluetooth on my iPhoneX. 

- I have checked the apple system preferences for sound, nothing out of the ordinary. I had the system audio volume at the same level for both wired and wireless tests.

- I have tried un-pairing and reconnecting, no change

- I have tried powering the headphones on and off, no change

- my headphone firmware is the latest version

Product: QC35 II

Thank you!
