a perfect noise in the subway or on the street

Rediscover silence, we do not think enough to our ears and sometimes if you put a noise-canceling headphones for a day, you can not you spend the day from when you refer the same route without.

Bose is the precursor of noise-canceling headphones, the biggest competitor of this model is the ZIK Parrot 2.0, but I quickly stopped the Bose because I think it has several advantages:

-DES BATTERIES:
The QC25 uses one AAA battery, its may seem trivial, but the big + is that if the battery runs out of juice, you just replace it with another, helmets with integrated battery must be recharged for use.
-DES BATTERIES (2):
As soon as the QC25 falls stranded stack, it affects only the noise portion, the helmet still work, even if the sound seem more "muffled", again it is because this is a helmet JACK was taken, so a simple connection, but when compared to ZIK Bluetooth 2.0 which is, well, no battery, over Bluetooth, and therefore more sound, that simple.
-WEIGHT:
The QC25 is lightweight and can be worn around the head, with a discreet design
-TRANPORT
The headset is supplied with a hard case also includes a slot for a battery, and a plug adapter davion 2 jack (also transformable in 1 jack)
-Cable JACK AMOVIBLE
No more problems jack breaks and requires a complete repair of the helmet with a removable cable, you can change the market and thus remake your helmet cheaply.

Defects:
-the cable jack:
Why say it's a failure as I just said it was convenient, it is because unfortunately, Bose only manufactures for Apple, Android forgetting (95% of the market) and therefore the original remote control on an Android only be used to hook, hook and passed to the next song.
This is therefore a pity that Bose did not provide an Android cable for 300 euros headphones

Little more
-the micro
shame that a microphone around and analyzing noise and leaving past that user's speech does not exist with this model because Bose has managed to do so, but on his helmet for driver, or this function allows you to switch a call on your lawn mower without the person you are talking to does noticing (I did), but it's not a headset for hands-free, because of its size and price (~ 1000 Euro)
