Description
64 Audio Apex Modules, or Air Pressure Exchange modules are pneumatically interactive vents that release air pressure in a sealed ear canal. This venting alleviates listener fatigue and opens the soundstage. Apex comes in four variations, mX, m12, m15, and m20. All of 64 Audio’s current IEMs feature Apex technology, although the Tia, Trió, and Fourté models contain an internal Apex module to preserve the Tia acoustic chambers.
