I have the H500 and it is very awkward. I believe that it was one of the first headsets to come out when the RAZR first came out. It works well with my phone but it does not fit. I chose it because at the time it looked smaller than the other headsets that were available through T-Mobile. Unfortunately, I have tried different ways to keep it on my ear but nothing works. Right now I wear it with the hook under my ear instead of over but it sticks out. It does not fit snugly against small ears. Now that there are actually smaller headsets out, I will be investing in one of those. I don't recommend this one for women because our anatomy is usually more petite than men.
