3MAX™ are custom-fit, tour-ready triple-driver in-ear monitors with the comfort and isolation of soft silicone earpieces. Our proprietary design includes twin-drive bass speakers paired with a dedicated, precision high-frequency driver via a single passive crossover, providing higher sensitivity for a more potent SPL output, plus greater bass headroom. The 3MAX is made from transparent, medical-grade soft silicone and comes with our field-replaceable coaxial cable system. Custom colors and various cable options are available.
