First of all let me comment upon the good, the function of the device. The earphone sound is fair with the main issue being inability to get it positioned correctly. The microphone is good with clear sound, good placement and great sound isolation. The USB connector was recognized easily and set up without problem in Skype.
Unfortunately, the rest is bad. The swivel on the earpiece is annoying, it swiveled into the wrong position often when I tried to put it in and tended not to stay put when I turned my head. The flexible ear hook is a little too wimpy. Sure its comfortable, because its so loose it likes to fall off. Also, although I havent had it long enough to have it fail yet, the cable from the headset to the 2.5mm jack is of the cheap two-wires connected together kind that has failed for me many times in the past. Oh and between the USB connector and the headset there is way too much cord, enough that I taped all the USB cord around the the dongle thing, which is quite large.
So to summarize, bad fit, cheap wire, good microphone, USB connector too large and with too much cord.
