Although listed as compatible with PS4, it is NOT compatible. I've tried a few things (like plugging in the device when the PS4 was off, trying to turn it on in the device menu, plugging it in before the game starts, etc.) but nothing helped to register it. I connected it to my computer and it registered immediately. I had an old Rockband microphone and the PS4 picked it up with no problem, so the problem isn't with the PS4, it's with this unit. Other reviewers said it wouldn't work for their PS4 and I thought they might have a defect, but no it's a device, it's just not PS4 compatible even though it says so. Don't waste your time. .
