I recently bought this device to go with my new Motorola E815 phone. It connected beautifully with the phone straight out of the box. I must say that reviews I read were correct. So far, the sound quality is very good, and everyone I talk to says they can't even tell I am using a headset! The only minor complaint I have is that it took me a little bit of work trying to find the best fit for my ear. It is not the type of headset that that you can just throw on and go. But once you have fitted it correctly, it is very comfortable and hardly moves around. Overall, I am very pleased with my purchase, and would recommend this product!!!
