This headset has good clarity. It holds a charge very well. But I do miss my Motorola H300 using a regular battery that lasts for months!!, but the range was terrible. The two downsides that the Plantronics 510 headset has is that it's not compatible with MAC computers. After following the instructions several times. I googled Plantronics 510 for pairing to the computer os x to discover that there are other MAC users that are not able to pair their wireless headset to their MAC computers/laptops.
