"Fake" Lightning Earphones Requires Bluetooth to be on (iPhone 11) - Video Evidence for Shopee 

Uploaded at the request of Shopee customer service, because I complained that I was misled by a merchant who advised that the particular set of lightning earphones I'd be buying would be able to be used on iPhones without turning Bluetooth on, but it turned out to be a lie. Here's the evidence.
I later did a little bit of digging and found out that the rights to use the lightning cable in this manner are exclusive to Apple, so there's no manufacturer except Apple themselves who's able to manufacture such an accessory.
