The Jabra UC550 is a fantastic telephone headset but the control fob is designed so far down the wire that it sits/ drags on the table, its protruding buttons waiting in ambush for you to un-mute yourself at the worst of times. This safety bumper prevents that while allowing full access to the buttons - when you want to. The flat base will let you attach the fob to a tie clip, desk, laptop etc with tape, velcro, a magnet. Don't want to risk touching the buttons while on an important call? Rest the whole thing upside down on a flat surface. No more conference call miscues!
