Only the comfort is neglected in this headset, I find the headset unfortunately somewhat uncomfortable to wear, it "sits" not right on the ear input, since the speaker input should have been made of a softer material. But you can alternatively ask loud and turn away from the speaker something ear, then passts again. The volume is sufficiently loud and can be changed using the +/- keys.
A good headset for those who live a long time in the car or on the PC phone calls via Skype and moving your hands want to free. Not suitable - for continuous operation - also because of the battery life of about 7.5 hours and the somewhat unpleasant comfort..
