This case works great with this headset. The key is orienting the headset into the appropriate configuration. The in-ear piece should be turned 90 degrees so that it directly faces the over-the-ear piece (and not toward the ear) and the microphone boom should be pointing in the opposite direction of the charging end of the over-the-ear piece. Once done,the headset fits snugly into the case. The case is clearly designed for the headset once the headset is in the appropriate configuration and the headset needs no further restraint to be kept in place. So my only criticism is that there are no instructions on orienting the headset to make it fit.
