New. Open box. By Antlion. Allows you to turn headphones into a headset. The ModMic can connect with PlayStation 4, Xbox One, and USB driven devices. It has a new noise canceling unidirectional mic capsule and better interference shielding that delivers a clear analog sound. It has a mute switch. The jack is 3.5mm. It appears to be missing the cable clips and the base clams with adhesive. What this means is that, although the microphone works, it is missing the piece that attaches it to the headphones. You just have to come up with a way to make it stick.
