I am planning to buy

I am planning to buy SONY ERICSSON W910i. I just want to know that the point where headphone is connected to the phone is not a one point pin plug. Its different, i mean its wider. Will the connection get loose if we move or shake the phone frequently ? If it would be one point pin plug then its guaranteed that it won't get loose, but since this is wide, i am afraid it will get loose. I am facing this problem in my nokia 6681. So asked you. Please help. Thanks
