extemely satisfied with this headset, especially the mute feature and ability to turn off the light which did not exist in Jabra BT 150 which I returned. This headset is built tough, is lightweight, and especially the earhook has a good grip on the ear. Even if u run it won't fall off the ear, this feature beats all other cheap brands of bluetooth headsets. U might find the H3 interesting as well, it was my first choice but I can get the H500 from cingular with rebates for abour 35 dollars but the H3 costs a lot more, I don't there is a big difference.
