Speakers are key when listening to music, but what about the cable connected to those speakers? Until Monster came along, no one had thought about how those cables could damper sound quality. Engineer Noel Lee, who was also a drummer, figured it out, and he set to work developing a cable that would ring true. It was a quick hit, and Monster grew to provide cables and other accessories for high-quality home sound enjoyment. Monster’s true claim to fame, however, was helping to launch the Beats brand. It was Monster’s unique infrastructure and advanced engineering that propelled Beats headphones and earphones to the top of the line. Though Monster and Beats have since gone their separate ways, Monster has continued to charge along, with its own line of headphones, a wide range of cables and speakers, and power solutions for both homes and mobile phones.
