I use this headset to game on PC, PS4, Xbox One, WiiU and PS Vita. The sound is completely natural. Meaning that there are no added effects or sounds other than what the game is offering, so you get to hear the game exactly how the developer intended you to.
I also own b&w P7's which are superior to this product in every way except gaming, IMO Sennheiser really nailed what they set out to do with this headset. It all comes back to that natural sound these offer and the great mic.
You will need a separate adapter PCV 05, if you want to use the mic on Xbox live or PSN. It's $15 and converts the Y connector ( mic & audio) to a single plug so you can plug into the Dualshock4, xbox one controller, wiiu gamepad, or vita and use voice chat. You will also need the Xbox one chat adapter to plug into if using microsofts console.
This headset is a tank. Its light weight, but very solid (plastic) and even though it hasn't happened I know it could take a drop to a hard floor and not be damaged.
The mic is off when raised, you simply lower the mic to turn it on and chat away. There is a volume wheel on the right side of the headset. This is one of my favorite features just for the ease of use, you won't realize how much you will use this until you start using the product, at least I didn't. The volume on the wheel adjusts the sound and chat from 40-100%. You can't turn the sound off with the dial alone.
If I'm not going to be using voice chat I plug into my reciever using the supplied larger plug. I do notice a difference in sound. It sounds better than when using them plugged into a controller. It has more bass and can be turned up louder, but you can't use the mic. So the sound quality of this headset is somewhat determined by the source of the audio and the power it outputs. That being said, they still sound very good while plugged directly into the controllers I listed.
Almost forgot to mention how comfortable these are. The plush velvet ear pads are very soft and flexible. They feel great around your ears and pressing against your head for hours is a non issue. You forget your wearing them after awhile. These are open, so you can hear everything going on around you, they also leak sound, so others can hear them somewhat.
I'm probably forgetting something but this is a long read already. If you've made it this far thanks for reading and if you couldn't tell, I definitely recommend these for any gamer looking for a quality headset.
