The attachment system was not too more, I had a little trouble at the stall, and I is not used to serve me with bluetooth headsets, I feel it's going a little m 'annoying if I have to give it regularly.
I was a little disappointed by the sound, but can be simply because I do not have the habit of the atria and I'm more accustomed to mono sound: basically, the well understood what tell me and seamless, but I found the sound quite nazillard and I hardly recognized the voice of my interlocutor. I do not know if it's better in the competition or if it is a common feature in this type of product.
Buttons: simple, no complaints (on / off, the + / -). You can unhook directly by pressing one of the buttons.
Note that it is possible to use the headset to listen to music on their smartphone: nice option even if next sound quality is pretty awful necessarily.
Doc minimalist but found all alone options. For the couple, I had no need to code and startup is high speed.
Nice to put it out for the save.
A cable is included for recharging (USB). I can not yet assess the autonomy (another obstacle for me to use these headphones, I do not think too recharging) given at 6am by the manufacturer and 150h off communication.

FINALLY:
The Bluetooth headset is recommended to avoid keeping such glued to his ear (especially in rural areas or far from the antennas) and is also handy to avoid going out as his (which, more and bigger, is often stored in a bag and not in his pocket).
This headset lets you get straight, and the sound seems constant and clearly audible even if personally I find them difficult recognizable voice with.
Anyway I'm still not convinced: the system of fixing the latter strongly displeases me and will not let me take the plunge.
I'll try again to convince me but I am still waiting the perfect headset that very little recharge, attaches easily without maneuvers, lets forget, and if possible give a more resembling that of a helmet (but for now, I stay with my headphones)
