It have both Motorola's H350 or H500 and both work quite well, fit well on the ear and are not too heavy (like my old Jabra BT800). The problem I have had is when placing them in the Motorola belt pouch (not included but an accessory I like to use rather than keeping the headset in a pocket), both of these headsets will get their call button pressed and make unintended calls. In 2 days, I have made at least 6 unintended calls to 4 different people. I never had this problem with my Jabra BT800.
