Hello Napu77,
Thank you for writing in. Can you confirm that these are the headphones you have? - https://bose.life/2JOc6w1
If so, here are the reset instructions:
- Turn the headset off and wait for 30 seconds.
- Plug the headset into a USB power supply via USB cord and wait 5 seconds. (Power supply needs to be plugged into the wall with power on).
- Unplug USB cord from the headset and wait 1 minute.
- Turn on the headset and test if the headset works properly.
Let me know if that helps?
Thank you again,
