No connection problem except that when I put the PC to sleep, I have great difficulty in ensuring the connection again between the headset and the key. I do not know that is a problem.
Otherwise small and functional.
Note
Having given up, I put the USB stick on a USB2 port on the back of the PC (before they are USB3 ports). As much it is not convenient when you have to put the helmet on another PC as connection problems have disappeared. Now connectivity is ensured easily. I gather that the pb comes from the key and not the helmet
But I confirm that comfort is moderate and that cinches. Compared to other headsets, considering the price unfortunately.
