My iPhone 7 aux isn’t working

It says Bluetooth on the box and to turn them on I have to use Bluetooth otherwise it plays through phone speakers. That’s how the lightning headphones work?

No, Bluetooth is a wire less connection (ie using no wires), Lightning employs a physical connection, ie the wire or cable, just as a standard audio jack would.

Find a set of earphones that have the Lightning plug (standard with all iPhone following removal of the audio jack socket) and plug into the Lightning Port, audio should automatically switch from speaker to earphones, if it doesn’t there may be an issue.

Those are lightning headphones, not bluetooth. iPhones have never included bluetooth headphones in the box.

In the past, iPhones came with a lightning - 3.5mm headphone dongle. That stopped a while ago.

It’s appears the seller may have purposely held back the Lightning dongle because of an issue with audio through the devices Lightning port, and the reply “It’s Bluetooth only” may be confirming that suspicion.

If they didn’t mention the lack of Lightning audio in the description you could go back to eBay and raise a dispute.

Basically, audio on iPhone should be possible via the internal speaker, earphone jack (if available), Lightning Port (for Lightning plugged earphones and via dongle), Bluetooth (ie wireless) and AirPlay (via WiFi, again wireless).

None of that is Apple, and although Bluetooth is on the box the plug is Lightning, as previously stated they are totally different and subsequently work differently.

Not wanting to change your mind with respect to returning the device, but you can’t rely on the third party Lightning cable/plug to test whether the Lightning Port is working correctly with regards to audio, for that you really need to use an approved Lightning earphone.

Whatever, it appears the seller hasn’t been all that forthcoming, so you shouldn’t really trust anything stated in my opinion.

Bluetooth doesn't use any wires.
