The main attraction of the Sony Ericsson HBH-IS800 headphones is their teensy size. Weighing less than half an ounce, these headphones rely on a slender strand of cable to connect the two earbuds. Such luxury and convenience don't come cheap, though: The headphones list for $200.
In general, the headphones delivered great-sounding tracks, with crisp vocals and warm (but not overwhelming) bass. Phone call quality was mostly good, too. Unfortunately, the headset's controls are minimal: You can use the action button to turn the headset on and off; to initiate, accept/reject, and end a call; and to play or pause tunes. But you can't use it adjust the volume or skip forward or backward through tracks.
If you're willing to sacrifice some phone and music controls for an ultrasmall headset with dependable audio quality--and the hefty price tag is no barrier--the Sony Ericsson package has got the goods.
