pro: lightweight, clear sound for ends of the connectioncons: either fits in ear or doesn't...but there is simple workaroundThis headset's sound quality is the best one I have found after trying ones from motorola, logitech and plantonics. I am told the background noise is hardly noticeable. The earpiece fits into the ear which makes the sound a lot clearer than the 'lay over the ear' style used by motorola headsets. If the earpiece doesn't stay in the ear, use a 'twist-tie' and shape it into an earliece loop. Its light and custom shapable. A black twist-tie will even match the headset. This trouble is well worth the superior size and sound quality of this pproduct!
