I purchased the H9 for 2 reasons. Small size and has an earbud for better sound and a comfortable fit. I am satisfied with both of those requirements. Sound quality from speaker is very good. The earbud is comfortable and blocks out ambient noise.The downsides are few, but there are two issues that trouble me about the product. 1. The microphone is very sensitive. In a quite area the person you are speaking with can hear you very clearly. However, any background sounds are picked up and makes it difficult for people to hear you speak. 2. The charging system comes with an AC adapter, however I also have a Motorola RAZR and a Y-Adapter for charging both phone and Headset. The H9 charger requires the same connector as the phone, so therefore the Y-Adapter isn't recommended for it. I have to now use two AC Adapters.Overall I like the product and would recommend it.
