The Plantronics headset is cheap and good, fits well into the ear, has a very long battery life and is loud and clear understandable. Have it on a HTC phone and Acer Liquid E700. In operation and there were no disturbances Good to use when driving and better than the speakerphone my Kenwood radios that brings too many noises. The design-related disadvantage of the headset is that it brings no music and therefore no system sounds at the entrance of SMS / Whatsapp etc., because it only allows telephone voice transmission. So if you hear even with the headset music or want to see videos or messages without disturbing others - does not go with this. Only for telephony speakerphone.
