The microphone, to me that is often used, my friends say it looks like a Kinect but less strong and it is a bit small
The USB stick for the plug, it flashes when the Xbox is off, and I have to unplug every time I turn off the console.
Otherwise, it's great, autonomy of 10 to 12 hours depending on usage, charging completed after 3 hours. Little advice, to change the color, we must hold the MODE button until the chosen color. Very comfortable, easy to plug, barge design, I recommend it for every gambler and having 110 euros to spend in a great helmet. Hoping to have helped you in your purchase quite complicated, given all the helmets available.
