The object is very stylish, neat and well finished.
THE BIGGEST: it has an active noise reduction. If you do not know, in a few words, it's magic and it is for me THE most product. If one is in a noisy listening environment (road traffic nearby in a public transport such qu'avion, train, etc ...), you will appreciate enlencher the system and to find suddenly that all the external surrounding sounds are very strongly attenuated. The active noise reduction works even without music in the ears; you put on the headphones, and you enjoy the silence during your trip, I LIKE.
Then there are all the features you expect from a premium headset:
* Quick and easy bluetooth apparaige
* Connection jack if necessary (no need to have a charged battery, in this case you get the same helmet with empty batteries - attention, active noise reduction does not work in this case)
* Volume buttons (+/-) and passage of a song to another
* Finally, the port is very nice, small pads around the ears are significant and help maintain the headset for hours.
Cons:
* A little too low for my taste
* Consumption mode "active noise reduction" (but it is inherent in the reduction system)
However, it does not hinder the rating 5 stars, because it is an excellent product quality / price ratio.
* I have some problems when I pair with my iPad, the system seems to consume too much memory and I have some crashes on the iPad by watching YouTube videos. I have yet to know if it comes from the iPad or headphones.
Few systems currently have the active noise reduction is really what is the highlight.
