A crazy experience — I lost my earbuds in a remote town in Chile, so tried buying a new pair at the airport before flying out. But the new wired, iPhone, lightning-cable headphones didn't work. Strange.
So I went back and swapped them for another pair, from a different brand. But those headphones didn't work either. We tried a third brand, which also didn't work.
By now the gift shop people and their manager and all the people in line behind me are super annoyed, until one of the girls says in Spanish, "You need to have bluetooth on." Oh yes, everyone else nods in agreement. Wired headphones for iPhones definitely need bluetooth.
What? That makes no sense. The entire point of wired headphones is to not need bluetooth.
So I turn Bluetooth on with the headphones plugged into the lightning port and sure enough my phone offers to "pair" my wired headphones. "See," they all say in Spanish, like I must be the dumbest person in the world.
With a little back and forth I realize that they don't even conceptually know what bluetooth is, while I have actually programmed for the bluetooth stack before. I was submitting low-level bugs to Ericsson back in the early 2000's! Yet somehow, I with my computer science degree, am wrong, and they, having no idea what bluetooth even is, are right.
My mind is boggled, I'm outnumbered, and my plane is boarding. I don't want wireless headphones. And especially not wired/wireless headphones or whatever the hell these things are. So I convince them, with my last ounce of sanity, to let me try one last thing, a full-proof solution:
I buy a normal wired, old-school pair of mini-stereo headphones and a lightning adapter. We plug it all in. It doesn't work.
"Bluetooth on", they tell me.
NO! By all that is sacred my wired lightning adapter cannot require Bluetooth. "It does," they assure me.
So I turn my Bluetooth on and sure enough my phone offers to pair my new wired, lightning adapter with my phone.
Unbelievable.
I return it all, run to catch my plane, and spend half the flight wondering what planet I'm on. Until finally back home, I do some research and figure out what's going on:
A scourge of cheap "lightning" headphones and lightning accessories is flooding certain markets, unleashed by unscrupulous Chinese manufacturers who have discovered an unholy recipe:
True Apple lightning devices are more expensive to make. So instead of conforming to the Apple standard, these companies have made headphones that receive audio via bluetooth — avoiding the Apple specification — while powering the bluetooth chip via a wired cable, thereby avoiding any need for a battery.
They have even made lightning adapters using the same recipe: plug-in power a fake lightning dongle that uses bluetooth to transmit the audio signal literally 1.5 inches from the phone to the other end of the adapter.
In these remote markets, these manufacturers have no qualms with slapping a Lightning / iPhone logo on the box while never mentioning bluetooth, knowing that Apple will never do anything.
From a moral or even engineering perspective, this strikes me as a kind of evil. These companies have made the cheapest iPhone earbuds known to humankind, while still charging $12 or $15 per set, pocketing the profits, while preying on the technical ignorance of people in remote towns.
Perhaps worst of all, there are now thousands or even millions of people in the world who simply believe that wired iPhone headphones use bluetooth (whatever that is), leaving them with an utterly incoherent understanding of the technologies involved.
I wish @Apple would devote an employee or two to cracking down on such a technological, psychological abomination as this. And I wish humanity would use its engineering prowess for good, and not opportunistic deception.
I don't want to rain on your parade, but maybe that's more of an indictment about ridiculous licensing costs for lightning
LOL. Not in this case. Cheap headphones do not pay Apple a dime. And Apple can’t go after every little headphone manufacturer they have real things to deal with like entire knock off Apple Stores that push millions of dollars a month.
In this case, the answer is less insidious. It’s the batteries. These headphones have BT but no batteries, hence why they are wired (need the power).
Why do they need Bluetooth at all though? Why not pull the audio through the Lightning plug like official Apple accessories do?
If I had to take a guess, it's because the audio signal coming out of the Lightning port is encrypted because Apple hates everyone who isn't them
Two reasons. One, it’s actually expensive to wire up lightning to audio. Because the connection is digital, not analogue like the headphone jack. Two Apple can detect data thru software and even disable it, leaving the headphones useless. Why would they? Because you didn’t apply for their mifi program and pay them. These headphones don’t have data, they just plug directly into power.
Its basically how they bypass the “Apple tax.”
Bluetooth's digital too, my guy. You need a digital-analog converter either way. It's just that when you use the Lightning port for audio you don't also need a Bluetooth radio. Besides, USB DAC chips are like a dollar.
Also you just proved my point that they only did this to avoid licensing fees.
Congrats, you just figured out why they include BT + Lightning from a technical side 👏
As for proving your point, if you need that my guy… you are so right that you define right. There is no one more right than you are here.
He's right
To add to it, you probably also have to deal with parts sourcing. You can probably scavenge Bluetooth radios from several generations worth of equipment or get cheap from China. In contrast, a Lightning cable that can turn data to sound is likely really hard to come by.
