Review on White Plantronics Explorer 500 Bluetooth Headset for Mobile Devices by Erik Sanders

This is the third unit I have purchased. They generally work well but don't really have 7 hours of talk time. I'm curious if the last product I bought from Revain was a returned product being sold as new. All others came with 3 different sizes of silicone eartips, while this one only had the largest silicone eartip in the box. It's not good because it's for my wife and she has very small ears. The big tip of her ear hurts her.
