Apple includes a Lightning headphone adapter with iPhone 7. But can I connect my Lightning headphones to my computer or another device with a 3.5mm jack? Is there a female Lightning to male 3.5mm plug adapter?
If you are waiting for an adapter to use Lightning headphones in a 3.5mm headphone jack, don't hold your breath.
Apple includes a Lightning adapter with every iPhone, which allows standard 3.5mm headphone plugs to be used in a Lightning port. These convert digital audio output from the Lightning port into an analog signal delivered to the headphones.Reversing this adapter to provide a female Lightning connector and a male 3.5mm plug would make it possible to connect Lightning headphones to a standard 3.5mm headphone jack. However, this would mean converting the audio signal from analog to digital and back again.
Apple is not likely to encourage the resulting decline in audio quality, simply to make Lightning headphones backward compatible with 3.5mm jacks.
