In my old job I used headphones a lot while driving on interstates and I have been through a lot of different headphones. This one is the best for many reasons including sound quality and comfort. The feature I love is the mute switch and volume control on the cord. I can mute or control volume without having to look or fumble with finding my phone, I just reach to mid-chest level and there is the control.In the office it is nice too. I don't like holding my phone to my ear for extended periods and the headset gives me comfortable hands-free without getting a crook in my neck, never mind the electromagnetic radiation from the cell phone. The cushioned ear piece is very comfortable.People I call have never complained of poor sound quality with this headset but they have with other, usually cheaper, ones. The sound quality is very good. The microphone does not pick up a lot of ambient noise so I can do the dishes while talking and the person on the other end is not aware of the noise.
