Monster Classic. These are the cables that started it all. When founder Noel Lee demonstrated definitively that the cable you use affects the sound you hear. Old Reliable Is Back! Plucked straight from our early days, Monster Classic Coil brings back the ‘70s style and sound with the quality that Monster is known for. Monster Shapes the Sound You Love Before Monster, pro audio cables were an afterthought. Manufacturers simply made products that carried sound from one point to another. Monster changed that by developing technical pro audio cables that are not only durable and roadworthy, they are designed to enhance the characteristics of a player’s style and equipment. For more than 35 years, we have been working with top-name artists, producers, and engineers to shape the sound of the music you love.
