This headset was purchased to replace TWO crappy jabra freespeaks.  This is very small, but unlike the goldlatern bluetreks or the Jabra, does not hide its mass well; it all sits right outside your ear, and in completely inconspicuous.  With my old bluetrek and even the jabra, my hair hid most of it, which for me is a plus, as I do not use Bluetooth headsets to impress people or get atttention; I don't want peoples attention and questions.
