Title: comfort, background noise not acceptable
Review: I owned this for a few weeks and found that it was a bit uncomfortable when wearing for more than a few minutes.Also, when using in the car, the person on the other end had a very hard time hearing me due to all the background noise (even with the windows closed and radio off, of course).I do, however, like the little battery charger and clip that comes with it -- it made it easier to carry around (ie. you could clip it to your briefcase, belt, or phone holder).I sold it at auction and bought the 510, and it seems a bit more comfortable, and also produces less background noise in the car. however its a bit bulkier.
