Cellphone now is a popular thing as almost everyone has one and brings it everywhere. For me, cellphone is not only a call tool but also a music Walkman. When I was outside, I always felt lousy about the headphone cord. Sometimes it would get fouled up in other thing, and sometimes it would be drawn away by other people when I was in the crowded subway or on crowded buses . So I like Bluetooth very much , since it could let me feel free when I was listening to music everywhere. And when I was on calling, it could free my hand and allow me to do something else when I was on the phone .
我是梅干啊
