This splitter adapter features one 3.5 mm plug and two 3.5 mm female connectors, allowing you to add a mono microphone input as well as a stereo output to your PC/Laptop, through a single 3.5 mm audio port. While some of the newer laptops from Apple® and Dell® feature only a single (4-position) 3.5 mm audio port that supports both audio input and output, this innovative headset splitter adapter breaks the audio port out into two distinct ports - one that can be used for a microphone connection, and the other for connecting external speakers.
