The USB and headphone should be reversed - when charging / sync cable comes out the top this is a problem using the phone while hooked to a PC or charging. This is a typical situation for me.


The n73 headset comes out the top, this is practical as you point out.

It would be more like a phone if cabels came out the bottom, not nesesary with the head set as you dont hold it up to your ear.
