iDARS Lightning to 2.5 mm Aux Cord, MFi Certified Audio Cable with Mic & Volume Control Remote for Headphone, Extension Cable Compatible with Bose QC35/QC25 AKG Y50/Y500 Sennheiser PXC550 JBL (Black)

Great quality. Tested and works well

Threw away the packaging before I used it. Mistake. Looks right, connector snapped in and was tight....but would never deliver signal to the headphones. Sound played through the phone speakers. Nothing I tried would resolve this. I wasted my time & money on this item.
