This is my first Bluetooth headset, but my 4th Plantronics headseat. This purchase was my first cordless and its been a pretty decent unit. Voice quality has been reported as clear and clean unless its very windy. Wind noise sometimes requires me to plug in my old corded headset in the car unless I'm running the A/C. I like the range, and often leave my Blackberry on my dresser and walk around the house with just the earpiece. Battery life is pretty good, around 6-8 hours talk time. I wish it had a car charger, and I wish they wouldn't flash the power light when it is running; which is totally stupid. When driving at night in the car it is a safety hazard because the blue light is bright enough to reflect off the auto glass and mess with your night vision; I suggest some black tape over the power light for night driving. Mine just bit the dust after 1.5 years, as it won't take a charge even though the charger is putting out 5.3 volts (rated at 5.0 volts). Tech support suggest I replace it, but I was hoping it would last a bit longer than just past the warranty period. I may buy another simply because the other features make it worth the money. To get a better unit I would have to spend $100 or more.
