Although our keyboards and mice are designed for use with computers, they can be used on PS4. However please note, most PS4 games do not support a keyboard and mouse.

When using a (wired) keyboard or mouse with a PS4, make sure it connects well with the PS4. If the PS4 has a connection on the back, connect the keyboard/mouse to the USB-connection on the back of the PS4. Or alternatively use an extension cable or USB hub.

You can use our mice and keyboards on the Xbox One.

Please note that Xbox One supports the use of mouse and keyboard in some games and apps, but it doesn’t work for every game or app. The game or app publisher must enable this feature for their content.
