This is a good headset for the price, but it does have some major problems. First, I should note that I use it primarily with my cell phone, not with my cordless phone at home. When I have used it at home, I have found the sound to be fine. When using it with my cell, however, and particularly in the car, I find the volume to be too low. Even with the volume on the head set and on my cell turned all the way up, it is very difficult to hear over the sound of the car. By the way, my car is not that loud, and I have not had this problem when using other headsets. My other complaint stems from the little black sponge thing that covers the ear piece. They are FOREVER falling off in the car. Which, when you're driving, means they are lost to you until you can stop and look for them. Given their size and color, they might be lost for good. The ear piece is uncomfortable -- and the sound quality is terrible -- without the sponge cover. Bottom line: although the headset has been useful, I'm looking for another model that provides better sound quality and doesn't use those little black sponge things.
