When you first receive your headphones, you must adjust the rubber-coated memory wire to fit the contour of your ear. Make sure the bend in the memory wire is smooth and free of kinks or sharp turns. Position the foam side of the speaker assembly firmly against your ear, directly over your ear canal for best sound quality and comfort. You can bend the memory wire into any shape you find most comfortable, so continue to readjust until you achieve optimal fit. Angle the speaker outward so that it lies perfectly flat against the angle of your ear.
*Use the cable slider to tighten.
