In 2016, Apple removed the headphone jack from the iPhone for the first time and from then on included the Lightning to jack adapter with new devices. Now this will no longer be the case in the future. case.
Apple will apparently no longer include the small lightning-to-jack adapter with the new iPhones. That is at least what Cowen analyst Matthew D. Ramsay claims. He analyzed the quarterly report from Apple's supplier Cirrus Logic and came to this conclusion. The company produces audio chips for the iGroup, which are also built into the adapter in question. But that no longer seems to be the case.
However, it is also conceivable that Apple has simply changed suppliers or taken over the production of this chip itself.
