There are two general ways to connect your ModMic Uni / Kimura to a PS4 / PS5:
Connected to the controller with a Y adapter, aka a TRRS/CTIA (tip-ring-ring-sleeve) adapter - the type that lets you plug/combine a mic and headphones into a single 3.5/2.5mm jack. The plug of the adapter should look like the bottom image in the photo below. Make sure the Y adapter has ports labeled specifically for your headphones and your mic.
The connection will be ModMic/Kimura > Y Adapter > PS4/5 controller.
Connected to an open USB port via a USB Sound Card. The connection will be ModMic > USB Sound Card > USB port on the PS4/5. Remember, there are two (2) 10-Gbps USB ports located on the back of the PS5, as well. NOTE: we are aware of reports of the USB ports in the back of the PS5 overheating and melting.

You might have to go into the Audio settings for your console to make sure your ModMic/Kimura is being read by it. Consult your console's instruction manual for more information.
There are other ways, as well, such as via an AMP / DAC. Don't hesitate to contact us at CustomerService@AntlionAudio.com if you have any questions.
