DetailsThis is an nCLOSE 12" 3.5mm audio extension cables for 3.5mm mobile credit card readers (right angle male to right angle female). (Used in the nCLOSE enclosures.) It's perfect to extend the 3.5mm TRRS audio jack! Most protective cases on the market (Otterbox, GumDrop, etc.) DO NOT work with 3.5mm mobile credit card readers, and this solves that problem. It's great for use with any 3.5mm TRRS audio device looking to extend the audio port. Compatibile with: RoamData, Rambler, uDynamo, Shuttle, UniMag I/II, UniMag Pro, Sail, PayPal Here, Square, GoPayment, iProcess and more.
