Our apex™ module pack comes with your choice of three out of the four we currently offer. These interchangeable modules pack our patented apex technology. Used with most of our custom and universal in-ears, they allow you to adjust pressure relief, noise isolation, bass attenuation, and mix width. m20 comes standard with most of our in-ear monitors and provides roughtly -20db of noise isolation. Of all the modules, m20 retains the most low-frequency energy and tight center imaging. mX features an 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. m15 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. m12 was developed for those who felt that the bass drop between m15 and mX is too drastic while providing -12dB isolation. Perfect for tracks where the bass is just slightly overpowering the rest of the spectrum. apex modules are designed to work in our current in-ear monitors (excluding Duo, Trio & Fourté) and our High Fidelity Custom Earplugs. Apex modules are easily interchangeable so you can switch between all variations quickly.
