I have been looking for a carrying case for my wife's bluetooth headset for close to a year ! The Motorola BLT-04 carrying case is the only one I have seen . No stores even offer an item like this ! So, I purchased 2 of them . One for me & one for my wife . I like it because it makes it easy to store and carry my headset . It also fits on my belt or on my wifes purse . It's not particularly attractive but gets the job done . My only complaint is that it pushes on the call button & causes my headset to light up momentarily each time you secure the strap . So far it doen't seem to affect the battery life . I think it works well for my H700 & HS850 but the H500 might have problems turning on by accident .This has been a problem for us with the H500 with out a carrying case .I have not been able to confirm this yet. So I can't say for sure.It's a good carrying case but could use a little more space away from the call button.Mike.
