This headset works rather well if you are sitting still, with no other noise around you. I have to speak in a rather loud voice so the person im speaking with can even hear me. The battery does last a good while on a charge, but overall, this headset should be given away, not sold. I spend most of my time driving, and again, it is terrible if you have road noise or the radio is playing. My friend has one also and the background noise resembles fingernails screeching down a chalkboard. So needless to say, the claim plantronics makes about "noise cancelling" is highly overated or they did their testing in a library somewhere...BUY SOMETHING ELSE!!
