I like this device a lot for it's ease of use, comfort and the clarity of conversation. It is easy for you to hear and even more importantly the other party hears you clearly also! I didn't  give it 5 stars because it disconnects too frequently without provocation. It connects easily has never lost signal during an active call,  but when idle it just disconnects for a while. This is definitely due to the device because my other devices ( motorola and Jabra ) did not do this with the same phone. However, in all other areas the Plantronics outshines those other two, especially comfort. I also have to say the price is not the best but simply worth it.
