No contact

I own an Xperia 1 and headphones WH-900N, also from Sony. Unfortunately I can't connect both devices. Is there any help for me? Thank you very much! SteSch

There is a trick I use when I have problems with Bluetooth connection:

• First forget the old Bluetooth headphones in your Bluetooth list, if it was paired before. 
• Bluetooth Pair via NFC or long press
• Immediately after pairing there is a popup window to check mark and press 'accept' if you miss this, you'll usually have sound and connection issues. 
• Which will connect Audio and Phone Calls
• After a few minutes in notifications, you'll see, "do you want to add as safety devices?"
• Yes.
