Music, just music!

This helmet, even "off" offers a beautiful sound reproduction of your favorite songs.
But it reveals its full potential when you push the "on" button, erasing simply the majority of the surrounding background noise.
Tested by car and train, the effect is stunning. It remains a background sound, but very subdued and very bearable, thereby not needing to force on the volume. Your ears will thank you one day.
Even when you pause the music (with the button on the headset wire), noise reduction remains active.
You can also make and receive calls on your mobile phone, the caller's voice remains clear and distinct even in the hubbub of a station concourse.
So certe, the price is higher than other headphones, but at least you enjoy your music.
Only drawback, when walking, not resonate in the headphones (with city shoes).
A helmet may be more suited to travelers and athletes.
