The casing device provides at least a fastening element arranged on the outer surface of the main member of a wired single-ear headset. At least one of the fastening elements should be located above the cable opening on the main member. As such, by fixing the signal cable in one or more of the fastening elements, the signal cable is redirected upward and extended along the main member to stride over a user's ear and then hang down to connect to a mobile phone or PDA.
