The Sescom iAdapt iPhone / iPod / iPad TRRS Plug to TRRS Jack Adapter Cable (1') adapts larger diameter plugs from a standard 3.5mm TRS or 3.5mm TRRS accessory to the smaller diameter plug required to fit many Apple iPhone, iPad, and iPod device cases. The cable features a small TRRS (tip, ring 1, ring 2, sleeve) with an 8mm O.D. plug that will fit many cases with the smaller headphone/mic input. Built with high quality shielded audio cable, the size adapter extension passes the left and right audio output and mic input. The iAdapt also reduces wear and tear that comes with repeatedly plugging and unplugging cables or devices into the small TRRS jack inside your iPhone, iPad and iPod.
