The helmet is a little heavier than a normal helmet. This is due to the embedded additional electronics. Nevertheless, it is not penalizing either cumbersome to use. By filtering term. It was worth the money. This helmet is of the type "closed", he already insulates the sound environment. When noise reduction is activated. We find ourselves in a filtered environment. I use the train. The train noise is not suppressed but filtered. It has a soothing side. In terms of quality, we also pay for. The finish is correct, ca exudes tough but all in finesse. The helmet is well shim on the head and ears
