What is ps4 mic in controller?

The PS4 controller has a built-in microphone that can be used for in-game voice chat. The microphone is located on the bottom edge of the controller, near the headphone jack. It is a small, unobtrusive microphone that is sensitive enough to pick up your voice clearly, but not so sensitive that it will pick up background noise. The microphone can be turned on and off by pressing the mute button on the controller. Additionally, users can use their own headsets or microphones by plugging them into the headphone jack on the bottom of the controller. Overall, the PS4 controller's built-in microphone is a convenient and useful feature for communication during online gameplay.
