Explanation
Wireless headsets use Bluetooth for communication. If the headset was previously paired but cannot connect, the most likely cause is that Bluetooth has been turned off on the phone-possibly accidentally or after an OS update reset it. NFC is used for short-range data transfer and pairing initiation, not sustained audio streaming. Wi-Fi and Tethering are unrelated to headset audio connectivity.
