A head band for mounting earpieces of a radio receiver comprises a continuous band or loop (12) of an elasticated strip material having a restricted amount of resilient yield with wiring (14) interconnecting the earpieces (11) which wiring follows a sinusoidal path so on stretching of the material the wiring merely straightens. The earpieces can contain electronic circuitry and batteries or these can be contained in a separate pod on the nape of the wearer's neck. |
