intelligent helmet!

This headset is simply sensational. The ANC works very well and I think as well as QC 25. Indeed the PNC is one notch below probably related form, the atria, which is not round but oval ... I loved: the distance from bluetooth focused, simple and quick NFC pairing, automatic stop function to the withdrawal of the helmet, the microphone button to amplify the voice of a speaker, autonomy .... I also use this helmet in hand kit free and nothing to say ... well, only minor, the size of the unit. Or not is assumed. I assume rather well as putting it on the outside by a cap desus ... its all good!
