Hope you're doing well. Can you please elaborate on what you're experiencing with Bluetooth on your headphones? Are you connect the headphones for the first time, or trying to connect them to multiple devices? Does your device find the headphones when you try to connect to them?
Thanks for the information, @DannyEardley. It's normal for the Bluetooth connection to cut out intermittently if the devices are far apart, or if the phone is in a pocket, bag, etc. This can affect the Bluetooth connection between the headphones and phone. If you haven't already, please try having your phone closer to you, and no obstruction between them. Do let us know how you get on.
