A headband includes at least one tubular element having a plurality of jointed parts arranged end to end and held together by a biasing spring. The individual tubular parts are advantageously formed, for example, from a single tube which is slotted on one side sufficiently to permit articulation between the individual tubular parts which are separated by the slots. A tension spring is anchored at the respective ends to the outer ends of the outermost tubular parts so that all of the parts are urged together. The jointed portions or slots are advantageously covered by a surrounding tube of a material such as a plastic. The complete headband construction advantageously includes a transversely extending tubular part which is adapted to fit over the head of the wearer, with at least one leg portion at each end which is adapted to extend outwardly from the transversely extending part to provide means for carrying the headphones on each side thereof. In one embodiment, the outer jointed part at each end of the transversely extending headband forms a downwardly extending leg to carry the earphone of the headset. In this embodiment, the sound by the spring transmitted through a tube, and all of the jointed tubular embodiment, form a closed tube construction with the joints being covered by a surrounding tube of plastic material. The downwardly extending legs on each side of the band are advantageously biased toward each other by which holds all of the jointed parts together. In one embodiment the headphones themselves are carried in tubular members which extend telescopically into the tubular leg portions of the headband set and the telescopic part is held in position by a connecting tension spring.
