Excellent helmet with light downsides

Positives:
* Very nice (but that's a matter of taste)
* High performance active noise reduction
* Good sound quality.
* The audio processing (listening room simulation, virtual speakers placement) is quite nice in non-extreme configurations, while I was really skeptical.
* Honourable Autonomy (see also negative)
* Comfortable
* Touch controls are nice, although sometimes a little too sensitive

Negative points:
* Manual which explains nothing at all. I still do not understand whether it was possible to activate the audio processing when the headphone jack is connected, and if so, how.
* The light breath induced noise reduction, normal in itself, is slightly different intensity on the left and right, which is quite disturbing when the music is at low volume.
* I have to sometimes turn off and on the headset to be recognized by the iPhone application.
* Honourable Autonomy, but no more, and no spare battery that came by default.
* If using extreme settings for audio processing (like "concert hall") the sound becomes painful.
* Not really intended for use with glasses.
* The presence detector unlocks if you have the misfortune to eat with helmet on head

In the end, the big positives outweigh me heavily on small inconveniences and hereby recommend this helmet.
