This is my second BT ear set. My first was a Motorola with deficiencies in volume, talk time, not to mention how awkward it was to store when not in use.Plantronics has taken care of all of these areas. This unit is plenty loud, even when traveling in a noisy vehicle at highway speeds. The pen type slip case that goes in a pocket or clips on a shirt at the neck line is a good Idea. By using rechargeable batteries (slides into the pen-style carrier) you don't even need to purchase a car charger or home charger. I've purchased a small portable charger that goes into the computer bag I travel with. Every morning, I replace the battery and the head set stays charged all day long. When I say all day long, I mean it. I'm on the phone over 3,000 minutes every month ... occasionally as much as 5,000 minutes. I love the Mute feature too; most BT head sets don't have this.The ear insert is the only thing I worry about down the road. It is always exposed and vulnerable. Not to mention the fact that it will probably discolor as it ages. This is the only reason I don't give it five stars. But, in fairness, if having the insert is the reason for the great volume ... I wouldn't have it any other way.I have been using this product for over a month now and I recommend it highly.Plantronics, one recommendation for you; make the battery rechargeable so I don't have to change it out every morning. Charge me for it, its all good.
