Pairing: Android + Mac - both immediately recognized. No problems, dropouts, the 1st unit pairt automatically 2 simultaneously no problem. Connection stable. 5 points
Comfort: 0 points (if possible). Who does not have elephant ears, has a problem. The ear gel is so far down that it is about 1/2 finger under the ear canal. Result when the strap is correctly positioned 1/2 fingers above the ear, of course, does not stop and pushes the gel out again. So you can only make calls when you are constantly pushing it with 1 finger in his ear. Adjustment impossible.
Voice quality: 0 points (if possible). The biliste 2 China speaker manages Skype without creaking etc. issue. The frequency spectrum of sounds really good, but the sound interference and spikes are not staying with the cheap passive speakers, even when USB headset, even when the powered speakers, nor anywhere else, only in the headset. Understanding is thus already severely limited. Skype Test Call & Rehearsal recording sounds something like "krrrrkrrrrkrrrrkrrrkrrr" - there is almost nothing or nothing has been said of the understanding.
After so unfortunately can not make calls (of course) and it also no hands-free but only a 1-heand-free is (which also goes if one holds the phone to the ear) unfortunately only 0 points.
