Things You'll Need
Instructions
Plug one end of a USB-to-microphone adapter cable into the USB port on your PlayStation 3. Only one end of the adapter will fit into the console, and it will fit into any USB port on the system.
Insert the red and green plugs on the end of your Sentry gaming headset into the microphone inputs on the adapter cable.
Turn on your PlayStation 3. Insert a game that is compatible with headset microphones. Compatible games list the microphone as an available accessory on the back of the package. Place the Sentry headset on your head and speak into the microphone to use it during gameplay.
