Not comfortable to wear and of average quality.

- The curved bracket to hang the headset around the ear seems very fragile. It is really just a simple piece of plastic removable end and hooking piece of plastic connecting the earpiece to the body of the headset. Motorola made models with a much more solid support and covered with a nice touch rubber.

- The receiver is (for me) to place a hell in the ear. When I finally arrived at the place, the headset goes outward from the ear, which gives you a look ... foolproof and is downright rude to your ear, since the earpiece also moves with the rest. So maybe it's me who does not know the place properly but it reveals another worry: the complicated poses, always compared to other models from other brands.

- A little voice tells you to ear if your device is on or off, connected or disconnected and so on. I admit it's a little nitpicking, but the voice of the lady is clearly depressed. If you did not have the moral, do not rely on it for you back!

- The sound quality is perfect (at least if you can correctly place the headset in your ear) but my correspondent complained, including car, hear me far despite a 4G network Orange 3 sticks signal on an iPhone 5 and 6 minimum.

- The button to hang behind the small plate "JABRA" at the back of the headset. I personally used to touch this part of the headset to hold it firmly in my fingers when I want to put the headset properly, which, as stated above, tends to be unstable in the ear. So, when I talk, I tend to always press this button without paying attention. It is very painful ...

Apart from this, we can congratulate Jabra to create a headset that have PAIR very quickly without loss of connection with any smartphone. Hats off to this point, but too light to make a good headset ...
