Turn off bluetooth on QC 35 ii?
I want to use the noise cancelling feature on my Bose QC 35 ii headphones WITHOUT connecting them to any device. Just noise cancelling without music, e.g. on an airplane, noisy office, bus etc. How do I turn off the bluetooth feature?
I do not want to completely disable audio prompts, since I still want battery information, and I most certainly do not want to sit with a dangling cord hanging out of the headphones. I don't want to spend ages deleting an existing pairing and then having re-pair every time I want to alternate between using only noise cancelling (turning bluetooth off) and listening to audio either. Most answers online to similar questions seem to recommend one of these options, but I refuse to believe that there is no way on these top of the line headphones to simply turn off bluetooth when I don't need it. What am I missing?
