This was a very nice bluetooth headset until I lost it. since it so small, I tuck it away and now I can't find it ;(. anyways, I had 2 great headset by Plantronics and samsung. both are very good, but if I had to choose, I would choose Samsung for it connects to my phone without too much hassle compare to plantronics 510 voyager, where I had to constantly reset my phone to get connect it. on the other hand Plantronics Voyager 510 voice is far superior to Samsungs (IMO).
