This is a handy carrying case for the Voyager 510 headset. Some reviewers mentioned that their headset would fall out of their case. I have not found this to be a problem in the 3 months that I have owned this so far. Someone mentioned in a review that if you tuck the charging end in to one of the two slots between the elastic at the bottom the headset will fit comfortably in the case. I found this to be true and it fits quite securely. The only reason that I'm giving this four stars is because it doesn't come with even a little card mentioning this and I really think that the company should tell you how to get your headset in the case!Other than that, this is a great case. It's not intrusive and it does its job well.
