The ultimate choice for those seeking the highest level of isolation, the m20 apex® module provides -20dB of noise isolation. This module 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 m20 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.
