Description: TRRS connectors are the 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). This breakout board makes it easy to add a TRRS jack to your prototype or project by breaking out each conductor to a standard 0.1" spaced header.

Nice little unit! I soldered it into place without incident. Maybe I’ll get to plug the earbuds into it and detect nuclear decay from my newly built bGeigie Nano Geiger counter.
This is exactly what I needed and works great! I’m glad that it is a 4 pin connector so I can fully use my headset!
This is the only 4 pin 3.5mm headphone jack breakout we could find anywhere online and its working great.
