I have had my headphones paired to my iPhone but needed to disconnect recently which wouldn't work so I had to 'forget the device'. Now my iPhone won't pair with my headphones at all. Is there a way to get them paired again?
Go to settings -> Bluetooth and make sure the switch is turned on:
Then make sure the headphones are in a range of up to 10 metres and in a state to be paired to the phone.
If this doesn’t work try:
Turning Bluetooth on and off on both the phone and the device
Resetting the device and restarting the phone
Contacting the device manufacturer
try resetting network settings first if you are reluctant to reset whole phone at once. It is settings-> general-> reset-> network reset.
also to rule out the obvious, try pairing headphones and phone both to a third working device which can be a laptop or some other speakers.
