The sound quality is very decent, you can change how it sounds in the EQ in the iCUE program and you can even turn on the built-in 7.1 surround sound. The mic quality is okay for comms but I personally don't use it because I have a studio mic with an arm stand so I have no use for it. If you're using it for a console it'll be just fine. Just be very careful of what you do... there have been incidences where the headphones stop working and no one knows why. I recently got this problem when trying to update the headphone's firmware in the corsair's iCUE. After an absolutely frustratingly long time and hard work uninstalling drivers and all of that, I fixed it by doing the same thing that caused the problem in the first place. The weight is a bit heavy but just fine because after all, it is a wireless headset. The cups swivel, but only a fraction. If you are to have them around your neck it's not constricting at all... (for me at least) I would have liked to have a function that lets me change the EQ presets or 7.1 surround sound by pressing the power button once.
Just a quick something if you already own the headphones is that you can soft reset them by turning the headphones off and holding the microphone mute button for 15-20 seconds.
