This is actually a replacement for one that I lost. I tried other headset from M******a and was very disappointed. The clarity of the Voyager 510 is great, it even signals you when you start to get out of range from you phone which is a big plus in my book. It is very lightweight and I often (almost all the time) forget it is sitting on my ear and have to remember to remove it when I get to work. I would highly recommend this to anyone wanting to go hands free.
