XS strings offer the maximum achievable tone life from a guitar string using D'Addario’s class-leading NY steel core and premium nickel-plated steel wrap wire which is then fully coated with their own dedicated coating. Furthermore, the plain strings are also polymer treated to complete the formula. This heady combination creates a louder set of strings that have pronounced midrange and bite, with rich harmonics with a near impervious shield which lasts, and lasts, and lasts, and lasts.
