Gaming headsets will only work with smartphones that support their connection methods. If you’ve got a gaming headset like the HyperX Cloud Alpha, which uses a 3.5mm TRRS connection, any phone with a headphone jack can use it—just plug it in and you’re ready to go. Gaming headsets like the Audeze Mobius or HyperX Cloud Mix can pair with your phone using Bluetooth. Most wireless gaming headsets don’t support Bluetooth, and if yours relies on a USB connection you’re out of luck (Some USB-C connections will work).
