The helmet fits perfectly in your head. The sound quality is acceptable, although the volume will not be as strong if used without the USB adapter. But if it is used, then you will definitely start to admire its deep bass and high quality sound. The noise level is not noticeable, even on the highest volume. A question perhaps the fragility of the USB adapter, because it has a very thin connection cable that could be prone to breakage. Overall, this headset has a high quality construction, never had any problems so far. A good combination of usability, comfort and elegance.
