Good size, good acoustics, but the ear loops are flawed.  They have two little (and I mean little) prongs that clip on to the headset and if one of them breaks, the loop will not work.  We have had four of these ear loops break in just this way.  We have had Motorola and other headsets that were heavier and less cool, but they did not break.  It is an Achilles Heel for this headset.
