Hi I33axn,
welcome to the Sony User Community forum..
Couple of thoughts..
Have you tried resetting your headphones.?
Press and hold the POWER button and the button together for about 7 seconds.
The indicator (blue) flashes 4 times, and the headset is reset to the default setting. All pairing information is deleted.
Once reset have you tried connecting by either NFC.. (See instructions from the user guide below)
Connecting with the smartphone by one-touch functions
By touching the headset with the smartphone, the headset is turned on automatically and then proceeds to pairing and BLUETOOTH connection.
Set the NFC switch to ON on the headset.
Start the app “NFC Easy Connect” on the smartphone.
Make sure that the application screen is displayed.
Touch the headset with the smartphone.
Touch the smartphone on the N marked part of the headset.
Keep touching the headset with the smartphone until the smartphone vibrates.
Follow the on-screen instructions to complete the connection.
Refer to the manual of the smartphone for the designated location to be touched on the smartphone.
Note
When the NFC switch is set to OFF, you cannot make a connection. You may set the switch to OFF to prevent the headset from turning on or connecting with other devices if you touch the headset with other device unintentionally. However, if you set the switch to OFF when the headset is connected with another device, you can disconnect the headset from the device by touching the headset with the device.
