Audio Cable TRRS - 18" (pigtail)

TRRS connectors are the 3.5mm audio-style connectors that you see on some phones MP3 players and development boards. TRRS stands for "Tip Ring Ring Sleeve " which reflects the fact that unlike a standard stereo connector this actually has three conductors and a ground. Some devices use the extra conductor for a microphone (like hands-free headsets) or to carry a video signal (like in some MP3/MP4 players) If you're hacking on something that has a 4-conductor audio jack being able to plug straight in will keep your build clean and simple.
