Functions: iPhone 7 adapter acts as a splitter from your lightning port into a female 3.5mm aux & female 8-pin lightning, allowing user to listen and charge at the same time. We wrapped it in metal package, and then brought in a high fidelity digital analog converter delivering you 48khz of lossless 24-bit sound. No pops, hisses or scratches here, just crisp robust audio. Easy use: The only thing you need to do is plug this smart, discreet and compact jack splitter into your iPhone and headphones. Portable and lightweight, you can have this dual cable with you all the time. So that empty batteries won't stand between you and your music. Note: It does not support microphone functions (cannot user microphone to answer calls). Package including: 1 x iPhone 7/7 plus dual function headphones adapter.
