I wouldn't use either, personally, because on-ear headphones hurt my ears. I use the around-the ear kind, and I like wired so I don't have to change the batteries. I would only get wireless if I was going to travel with them. If you are using them mostly for video games, then you have to use the kind your console needs. Based on your comments (which I moved to the discussion), you'll have to decide whether you want them to work with your PS4 or not... if that is why you wanted them, I think you should use the ones that work with the PS4. The other option is to return both, and use the money from both to buy a better pair.
