Seems like this is the umpteenth topic on this subject but here it goes: Sound works just fine, but the microphone doesn't. This is on the Xbox One and the headset was plugged directly to the controller. Tried a few different settings, restarting console, plugging back and making sure it's connected firmly, etc. nothing worked. Funny thing is my cheapo $20 Turtlebeach wired headset (which also plugs into the controller) works just fine so I know it's not an issue with my Xbox controller or console. Returning the headset (bought through Amazon) and considering buying another unit from Best Buy and give it a whirl again since the headset is very comfortable and the sound is very good for the price. Hopefully this thread encourages this issue to be investigated and taken more seriously.
