Bose QC 35 headphones - calls very quiet on Pixel 3a XL (other media volume fine)
In the last month or so I have noticed that when connected via Bluetooth to my Pixel 3a XL, the audio of phone calls is very quiet even when the call and media volume on my device is set to the maximum.
When I listen to music or a podcast, the volume is fine and the maximum is much louder than the call volume. I've checked my phone connecting to other Bluetooth devices and this isn't the case for anything except the QC headphones.
I have installed the latest update via the Bose app, and also tried disconnecting, unpairing and repairing and this doesn't seem to have solved the problem.
