The sound is okay but not as good as that of high-end headphones.
Some downside, however, have a big head, 60 cm circumference equivalent to a xl size, length of the cable between the headphones is limited "light gene".
Fortunately after my usual haircut (3mm on the back), the problem does not arise.
The super convenient buttons are easy to use at first. Having big fingers, you have to memorize the position of the functions of each button (Sound button is also used to increase music change depending on whether you press up or down) and the size of fingers is much higher that of the button, the grip is not easy but we get used to the system after the first long use.
The vocal indication of the autonomy of the sail is significant as is their autonomy dailleurs.
Rebooted a single time since I've served me and this conversation, prolonged listening to music (several sessions 2h hike).
The quality of the microphone is top and mitigation of external noise during conversations is pretty good.
This is a purchase that can do so with confidence, I recommend it for its excellent value for money.
I takes only 4 stars for the cable length.
