Not all audio splitters are made the same; here is a quick tip on how to tell if your audio splitter can also be used with your gaming headset.
On the tip of your splitter that connects into the audio port, you will see the metal contact. Depending on the type of metal contact you have on your audio cable will depend on the functionality as every audio jack is divided into parts. The tip, the ring, and the sleeve.
Each metal sleeve section has a different functionality. Sleeves with one ring provide basic audio. Two rings provide stereo audio, and three rings provide stereo audio as well as microphone capabilities. For the headset to work on devices and console with both audio and microphone, you would need a splitter with three rings.
