My AirPods worked perfectly with the iPhone, but one day the smartphone stopped seeing them. It seems that the headphones are just stuck and do not connect to any device.
The Apple headset is a fairly sophisticated and technological gadget that can easily hang. Fortunately, it happens quite rarely and you can reset at home.
To reset the headset you need:
1. Place both earbuds in the charging case.
2. Charge them so that both the case and the headphones have enough charge.
3. Open the case cover and hold the button on the back of the case for a few seconds.
A flashing white light will indicate that the reset was successful.
Now the headset should be re-attached to any of its devices.
Such a reset procedure is convenient to produce and before selling headphones.
