it really deserves 5 stars

compared to a Bose QC25 that, certe the noise is not as effective but it is equally aprciable because the accuracy of the sound is really the appointment. and quality of Bluetooth 4 is simply amazing what puts the qc 25 outless.
To the ear, the quality renders the very long distance bluetooth does not distort the sound at all, nothing I expected to have a sound best with the cable (which is a bonus) but no, it is more than convincing .
There again, good in the bass and treble, (I had heard of a 8hz peak, this does not mean at all, it rather brings into focus some punchy instrument), the tracks are very well balanced.
The equipment he embarks, namely simultaneous dual bluetooth appreillage, internal external microphones, the noise is still very effective, depending on the music you listen to, tend to listening to soft music with the AB, and nothing with pop songs rebounded.
It is worthy of the Air France company style with its built hostess. With sensors in the left atrium which suddenly know if you listened to music or not, it works wonderfully. You can even parameterize from a computer.
In short this gem is a technological feat. All that is said about him is checked, there is no hesitation.
His purple look really trendy while remaining sober. The finish is worth ten times that of beats headphones, with its arch covered with faux cook very soft and very comfortable headset.
The small Bonnus, when your little (e) ami (e) or your mom telling you, there has to press the button on the headset, and you hear absolutely everything that is said around you. Of very high class, you'll be addicted to music.
