The Recon Spark headset can be used with a PC, mobile device, and a Nintendo Switch.
In some cases, an alternate setup may be necessary.
If your PC has a single jack for both headset and mic audio, simply plug the headset in.
If your computer has separate jacks, one each for headset audio and mic audio, you will need to use the included PC Splitter Cable for full functionality with that particular computer.
Plug the headset into the PC Splitter Cable, then plug the PC Splitter Cable into the computer, making sure to match the Splitter Cable's plugs to the correct jacks. Usually these separate jacks are identified either by color (Green/Pink), or by images of a mic/headset next to the individual jacks.
MOBILE DEVICE/NINTENDO SWITCH SETUP
To use the headset with a mobile device or a Nintendo Switch console (while in handheld mode), simply plug the headset's main cable into the 3.5mm headset jack on the mobile device/Nintendo Switch.
