The Samsung Bluetooth Headset HM1200 not met so 100% my expectations. On the bike used, the called party does not stop smoothly what they say, because of the wind, which superimposes the spoken. In the car the situation is reversed, because I sometimes hear only bad what the caller wants to speak in my ear. The Car Interior noise is often louder than that you can readjust the volume as loud. Ie go slower and you understand what is being said again. Only downside is that there is only one English language manual. It must not be the same super thick manuals in 21 languages, but at least in the major languages (eg Engl.-Esp.-Dt.-Frz.-Ch.) should already sen translates the instructions, and German, I count with it. Well, in any case that is the Bluetooth connection always unkomliziert and made quickly. That was and is always surprising easily and quickly. Therefore, four stars are well rated.
