Compact, stylish, and very comfortable.  Currently one of the only headsets known to work well with the HTC Mogul.  I wear it all day and never run out of my charge, and sometimes even forget that I am wearing it because it is so lighweight and comfortable.  Amazon has top pricing on this product too.  I could buy two here for what I'd pay full retail elsewhere.  Sound is clear on both my end and the receiver's end.  Great product and great value.
