Using the same uni-directional microphone found in the ModMic5, the ModMic 4 is designed to isolate sound and minimize distortion from the surrounding environment. To help create a consistent, clean sound, the mic only lets in sound from one direction to radically reduce noises emitted from external sources. Designed to attach to your headphones, it fits on almost any pair of headphones with the included 3M adhesive. Simply stick the base onto a flat surface on your favorite headset and attach the mic—it won’t leave any residue when removed. When you want to move the mic, just clip it into another base clasp on a different device.
