You have to use the in-line mic on the cord, as neither the PS4 or Xbox One support standard Bluetooth headphones. Unfortunately.
This means that you have to use the PS4’s built-in audio panel to mute the mic. Still doesn’t make the Crusher Wireless any less of a solid value. I included the bit about the mic because people are often curious about which cabling standard included cables use. Any cable that’s not “made for iPhone” should be using a cable pinout that complies with what the PS4 and Xbox One are looking for, and this is true in the case of the Crusher!
