Hi there,
I believe you have a massive firmware issue with the latest Q700 headphones.
Currently when updating the firmware or updating the google assistant into the firmware the headphones go into an unusual boot up and boot down loop. The process starts when either of these happen. I am now into my 3rd pair of Q700's and all have done the same thing at the same time.
The loop starts by rebooting the headphones, telling me battery and what it is connected to. The bluetooth function no longer operates, I cannot hear any sound from my cellphone or computer it connects to. It then does not play the boot down sound and simply turns off, along with the noise cancelling function. It then re-boots itself up, tells me the battery and connection again and it is a forever ending cycle.
As this is now my 3rd set of Bose Q700 headphones I am putting this down to either the firmware inside the headphones or that it is connecting to a Samsung Note 10. I have done multiple hard resets, tried all other trouble shooting options. It appears to be the headphones connection capability. This needs urgent attention from Bose as I believe this issue is occurring regularly for a lot people and furthermore there is no fix currently in place. This should be addressed in a new firmware update for the Q700 headphones.
Please Bose do not direct me to my local repairer. This is 100% the headphones requiring an immediate update!
Thanks,
Hayden
