ok the new quietcomfort 2 gaming headset come s whit microphone and a special pc desktop controller ....but there are other difference between both?
if I use headphones by connecting them with the wire, do I lose something in terms of performance?
I hope you've had a great time with your QC35 II Gaming Headset so far! The included desktop controller is for ease of access when controlling volume for your PC game audio. The performance of the headphones and the microphone is not affected by your choice to use the controller or not.
In regard to your second question, are you looking for the headset to play the same audio as what you are hearing through the Soundbar 700?
