I have Sennheiser earbuds and I want to use them with my Playstation 5. How is it possible to connect my Sennheiser HD 599 to PS5?

Insert the 3.5mm audio jack from your HD 599 headphones into the 3.5mm connector at the bottom of your PS5 DualSense controller.

After connecting, navigate to the PlayStation 5 settings. Go to Settings > Sound > Audio Output. Make sure the output device is set to the controller, and change the audio settings to your liking.

Because the HD 599 lacks a built-in microphone, you'll need to use an external microphone if you want to communicate while gaming.

With these procedures, your Sennheiser HD 599 should be compatible with your PS5 for gaming.
