Hello, I bought Noise Cancelling Headphone 700 and it is automatically turned off after some time even if I set Auto-Off to Never inside the Bose Music App. I read from other posting that "The headphones power off when you have not moved the headphones for 10 minutes." Is this true? Is there any way to disable this feature? I am using it when I sleep to block the noise and don't want it to be turned off until I wake up. Please help. Thank you.
