Summary: The product is slightly uncomfortable to wear for long periods of time. The earpiece doesn't feel comfortable most of the time because of the plastic, however, when the ear hook is on at a comfortable position, it isn't always a problem. The microphone seems to work fine.
Summary: Soundwise this little microphone works well although the position that it hangs down in front of the mouth is a bit awkward. It need a better support. Whether I have big ears I do not know but it was difficult to attached behind the ear, the arm that goes behind the ear is not well designed.
