Product Overview

Never take off your protective phone case just to plug in your headphones. This ultra-short 3-inch 3.5mm (1/8 Inch) 4-Pole TRRS Male to Female Audio Extension Cable features a specially engineered slim step-down plug that fits effortlessly into the deep, narrow audio cutouts of rugged phone cases, waterproof covers, and battery charging packs. With full support for stereo audio, microphone voice chat, and inline remote buttons, it also acts as a permanent "port saver" to shield your device's internal audio jack from repeated wear and tear.
