I am fan of logitech products and think that they are excelent, however this didnt diserve the five stars because it is too big, and the volume is a bit low so it is really hard to hear with the car windows open, besides that, it is great, very confortable (oviously not for a very long time) but for a couple hours a day it is really nice I have a plantronics and cant stand it for more than 20 minutes. Also it fits small ears and you can adjust the pressure wich is a really nice thing.
