A:AnswerThe cable on the tenkeyless version is removable, but the key switches are not. You would need to look at the glorious pc master race GMMK or the new logitech G Pro keyboard (much more expensive) for that feature. It is quite rare in the mechanical keyboard space at the moment.
A:AnswerSorry Gavin, I totally misread your question. It will work with PS4 via USB. I glanced at the question and thought you asked if it would work with PS/2 (the old school keyboard plug). I'm sure you would have figured it out but I just wanted to come back and clarify that my original answer is incorrect and I apologize for that. My bad! :)
