Does it work with PS4? No, Bluetooth capability does not work unless you have a PS4 Bluetooth adapter.
Does it work with PC? Yes. But as a sidenote, if you play CS:GO, there is an issue where using the mic forces the headset to default to a very low quality sound that cannot be fixed unless you disable the mic in the control panel.
Sound quality: Superb for $25
Does the noise cancellation work? Yes, not top of the line but it gets rid of ambient sound well.
How does it fit? If you have a large head or big ears, these headphones will HURT after 15-20 minutes of wear. Buyer beware.
