I haven't tried a bluetooth device in years, is pairing still godawful? I wish they would give you the option to pair through USB. Just plug in the host and peripheral and press the pair button, and it should automatically negotiate pairing. I don't care if it requires the hassle of occasionally having to plug something in to pair the two devices as long as it works 100% reliably.

Correct me if I'm wrong, but wasn't NFC at one point considered the solution for such out of band pairing? I think NFC headphones are still available for sale.

NFC was one possible solution for the "Out-of-Band" pairing defined in the Bluetooth spec.

The spec. allowed to exchange encryption keys with a different method than Bluetooth, Sony is using it on the Playstation to perform BT-pairing via USB.

Commercially, NFC was mostly used to initiate pairing, by having a NFC Tag on the accessory which stored the Bluetooth address, and a device scanning the tag would initiate pairing with the device directly.

The pairing itself is technically still done over Bluetooth, which is nowadays mostly a matter of confirming the operation...
