Very good BT headset

The general feeling is that this is a very good price / quality ratio. I decided to take the suite has its note on digitalversus, and the fact that I did not want to spend $ 300 in a helmet.

Zero level manufacturing problem it looks strong enough air for the price.

Sound quality level is very very good, the bass is there but not so ubiquitous beats, the sound is clear and quite friendly and allows to me to listen a little all types of music. The helmet really saturated that if I pushed her inside and out. I am very satisfied.

The helmet like pretty hot, so avoid if it's 30 degrees outside, but wish well to the head without too compress ears. I often over an hour on the head and I realize me more account.

Noise reduction works well in the TER I almost can not hear the sounds of the train, it hides very well the continuous and serious noises, for shrill whistling of the train on the rails it does cover has half but with music we simply do not hear anything around.
I will fly next week so I expect to see and I will publish my review to give an opinion on a more noisy environment.

Bluetooth sync / NFC worked in 2 seconds with my phone (Nexus 5).

Very good purchase, one regret: no cover is provided for storing the headphones, even a cloth could do the trick, but then nothing in nothing.

In short very happy with the purchase, a very good helmet, very good sound, BT working fine, Noise Canceling also good (I do not expect miracles anyway whatever the helmet).

Comes with a micro-USB cable / usb jack connector, and that's it.
You can not put 4.5, otherwise I would have done for lack of cover / storage bag.
