The headset is only 9 grams, you can feel it almost in the ear. A small bar is clamped and so you can set the set to the left or right ear.
The multifunction knob is almost invisible in the attached headset. Pressing him, so after a few seconds the connection is built up, a blue light illuminates and then a red. The connection to the cell phone (Samsung Galaxy) is very simple, I could not notice any problems. The sound is very good, you will understand the caller loud and clear.
The stereo headset has a standby time of 14 days. I could not test final, will report.
A USB cable is a small and instructions in English, which is in the case in a small side compartment with mesh.
Very functional headset with beautiful case, which is now in my car has a permanent place. Always ready and at hand.
