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 bass-heavy earphones into a mastering-grade tool with a very resolved sound signature. 
 
The mX houses 64Audio's 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 in 64Audio's current in-ear monitors (excluding Duo, Trio & Fourté) and their High Fidelity Custom Earplugs. Apex modules are easily interchangeable so you can switch between all variations quickly.
 
Modules are sold in pairs only.
