The helmet includes a control on the wire (with a small clip to attach to clothing), which can control the volume and mute the microphone. Everything is comfortable and can be worn for loooongues play sessions ...
By cons, once you put music, we feel that this is not so much his domain (the same time, we can not do everything - anywhere it is marked that it is an audiophile, after all ...).
I also like the length of cable supplied by Logitech. It does not look like much, but it's that kind of detail we see the attention paid to the product.
