I have an iPhone 7 with Lightning headphones. I got a connecting adapter to use 3.5mm compatible headphones on an iPhone 7. But, is it possible to use these Lightning headphones on the 3.5mm jack of my Dell laptop? I tried Googling and haven't found any converter/adapter.
The lightning to 3.5mm jack adapter that comes with the iPhone 7 should work with the Dell laptop and the iPhone. That adapter was constructed to work with the standard 3.5mm headphone jack that most devices use. I've yet to see a special 3.5mm jack, just because it was/is an industry standard.
