It fits Motorola's H350 or H500 nicely and sits securely on the belt. However, either of these headsets when placed in here will get their call button pressed. In the 2 days I have been using this case; I have made at least 6 unintended calls to 4 different people. I never had this problem with my jabra BT800. I am giving up on Motorola's headsets... I am going to try this case with a Nokia headset I ordered when it arrives and see if it still pushes that one's button.
