mX apex® module The mX apex® module features a new internal design to achieve the most open and transparent audio experience within the apex module family. It reduces the ambient noise isolation to only -10dB, but in return transforms earphones into a mastering-grade tool with a very resolved sound signature. The mX module will add air and focus to the mid-range while masterfully transforming the bass to achieve a true reference sound. The mX houses our innovative apex technology, which alleviates listener fatigue by releasing air pressure sealed in the ear canal. This venting enables musicians and music enthusiasts to listen more comfortably for longer, and adds to a more spacious, rich sound. Unlike a solid plug, apex offers a high fidelity listening experience, so you hear more of what you want at a lower decibel level. The mX apex module is designed to work with the any of our current A-Series in-ear monitors, U-Series monitors with apex ports, and our High Fidelity Custom Earplugs. You can easily switch this module for the mX or even the solid plugs from our custom earplugs. m15 apex® module The m15 apex® module features a combination of dual ambient ports (larger than the single hole in the m20) and modified internals to achieve -15dB isolation. This module is designed for an additional -4dB cut at 20Hz as compared to the m20, making it the middle ground between bass attenuation and isolation. The m15 houses our innovative apex technology, which alleviates listener fatigue by releasing air pressure sealed in the ear canal. This venting enables musicians and music enthusiasts to listen more comfortably for longer, and adds to a more spacious, rich sound. Unlike a solid plug, apex offers a high fidelity listening experience, so you hear more of what you want at a lower decibel level. The m15 apex module is designed to work with the any of our current A-Series in-ear monitors, the U12t and U18t, and our High Fidelity Custom Earplugs. You can easily switch this module for the m15 or even the solid plugs from our custom earplugs. m20 apex® module The ultimate choice for those seeking the highest level of isolation, the m20 apex® module provides -20dB of noise isolation. This module houses our innovative apex technology, which alleviates listener fatigue by releasing air pressure sealed in the ear canal. This venting enables musicians and music enthusiasts to listen more comfortably for longer, and adds to a more spacious, rich sound. Unlike a solid plug, apex offers a high fidelity listening experience, so you hear more of what you want at a lower decibel level. The m20 apex module is designed to work in our current A-Series in-ear monitors, the U12t and U18t, and our High Fidelity Custom Earplugs. You can easily switch this module for the m15 or even the solid plugs from our custom earplugs. m26 Solid Plug This is a replacement module intended ONLY for use with the custom-fit High Fidelity Earplugs. It is not recommended for use with A-Series custom-fit or U-Series universal-fit IEMs. Our solid plugs do not feature our apex technology but offer up to -26dB of isolation. The solid plug is designed to be the same size and shape as our apex modules, so listeners can swap them in their High Fidelity Earplugs for different levels of isolation in different environments
