"The functions like call rejecting and microphone mute are very handy. Furthermore, the buttons are well positioned; when using one of these functions, you don't risk pushing any other button inadvertently. However, I do not recommend it for listening to music, as the sound quality for this purpose is very poor, but when making calls, the quality was just as good as any other standard phone. Another great thing is that there is an AC charger included as well as the standard mini-USB cable. So for mobile phone users who don't necessarily have a computer on hand, they can still recharge the unit. Or it could even be plugged in the car, provided you have a DC to AC transformer."
