NFC (Near Field Communication) is a short-range communication that requires devices be within a couple inches of one another to communicate. If your device supports NFC, you can easily pair it with the headphones:
Pairing your Bluetooth® device with NFC
With your headphones powered on, unlock your device and turn on the Bluetooth and NFC features. Refer to the owner’s guide of your device to learn more about these features
Tap the NFC touchpoint on your Bluetooth device to the back of the inline remote. Your device may prompt you to accept pairing
Note: You may have to move the inline remote to different areas of the device to find the NFC touchpoint. It may not be directly in the center of the device.
Once paired, you hear “Connected to <device name>” and the Bluetooth indicator on the right earpiece glows solid white
