An assembly comprising an audio headset cable and a stopper element, for providing stress relief for electrical terminations of the audio headset cable, where the electrical cable comprises a plurality of separate conductors, a bundle of cable reinforcing strands, and an outer jacket at least partially surrounding the conductors and the bundle, wherein the conductors and the bundle protrude from an end of the outer jacket, wherein: the stopper element surrounds the end of the outer jacket and the portions of the conductors and bundle where they protrude from the outer jacket, the stopper element having a perimeter partially defined by a front face, a rear side and a side; distal ends of the conductors and the bundle protrude from the stopper element; the distal end of the bundle that protrudes from the stopper element is divided into multiple protruding bundle portions (32;34), wherein a first protruding bundle portion is wrapped at least partly around the stopper element in one direction and a second protruding bundle portion is wrapped at least partly around the stopper element in another direction; the front face of the stopper element is a generally planar face from which the distal ends of the conductors and bundle protrude, and wherein the first protruding bundle portion is wrapped around the perimeter of the stopper element generally in a first plane that is generally perpendicular to the front face of the stopper element, and wherein the second protruding bundle portion is wrapped around the perimeter of the stopper element generally in a second plane that is spaced from the first plane and generally perpendicular to the front face of the stopper element; the first and second protruding bundle portions are wrapped around the perimeter of the stopper element so as to go over the rear side of the stopper element. the stopper element surrounds the end of the outer jacket and the portions of the conductors and bundle where they protrude from the outer jacket, the stopper element having a perimeter partially defined by a front face, a rear side and a side; distal ends of the conductors and the bundle protrude from the stopper element; the distal end of the bundle that protrudes from the stopper element is divided into multiple protruding bundle portions (32;34), wherein a first protruding bundle portion is wrapped at least partly around the stopper element in one direction and a second protruding bundle portion is wrapped at least partly around the stopper element in another direction; the front face of the stopper element is a generally planar face from which the distal ends of the conductors and bundle protrude, and wherein the first protruding bundle portion is wrapped around the perimeter of the stopper element generally in a first plane that is generally perpendicular to the front face of the stopper element, and wherein the second protruding bundle portion is wrapped around the perimeter of the stopper element generally in a second plane that is spaced from the first plane and generally perpendicular to the front face of the stopper element; the first and second protruding bundle portions are wrapped around the perimeter of the stopper element so as to go over the rear side of the stopper element.
