Query: poor sound quality, nice design

i really like the way this looks, it's more stylish than any other bluetooth headset (arguable no one else cares-- at least they tried?). it also has a lightweight feel and as other reviewers have said, almost unnoticeable. it does not feel flimsy or shoddily constructed though. the battery is sealed in, and will either require service to replace or completely discarding the headset.i paired this with my macbook pro. the sound quality was unacceptable, both for talking and listening. it would crackle quite a bit and drop out very frequently. it seemed to be of a working quality when i was within 2-3 feet, after that it degraded to unusable (not 10 meters as it claims).
