This Audio wireless headset (which can still connect to the PC via USB) is very aesthetic and very comfortable. I did not feel tired even keeping several hours on the ears. It connects easily to a smartphone (tested with an Android Smartphone with a Iphone). The touch controls are well positioned and are easily accessible on the side of the helmet. The command answer / end really proves useful. On the practical side, it folds easily and fits into the included case for easy transport when not in use. The sound important part of a headset, is well made and with the equalizer, there is a choice, a simple press on the side button, between 5 predefined styles highlighting either severe or acute (those who enjoy stronger bass will therefore be filled). As flaws, I find this helmet does not have an excellent fit on the head and the beeps emitted during certain actions, quite unpleasant. This is ultimately a good product.
