Monsoon XTRM uses many of the same ingredients and technologies found in Monsoon. A carefully finessed combination of Perfect-Surface Copper+ & Long-Grain Copper Conductors, RF/ND-Tech, and ZERO-Tech but surpasses its namesake model with our best AC plugs, featuring Hanging-Silver over Red and Beryllium Coppers, for lower distortion and improved dissipation of high-frequency noise. This is Monsoon taken to the XTRM.
