This article explains how to pair a PlayStation 4 controller, also known as a DualShock 4, wirelessly to the console via Bluetooth.
How to Pair Your NEW PS4 Controller to Your Playstation (2 Methods)
To sync a controller to the system, especially the first time, you will need a USB cable. You can connect the DualShock 4 to the console using any USB 2.0 Micro-B cable. Although the system only has two USB ports, you can sync up to four controllers per player account.
Before turning on your PS4, connect the small end of the USB cable to the port on the top of the controller. Connect the other end to one of the USB ports on the front of the console.
Turn on your PS4 by pressing the console’s power button. It should automatically detect your connected controller and assign it to the first available player slot.
