In the latest H1, FitEar have incorporated ONKYO's Magnesium Diaphragm Balanced Armature (Mg-BA) driver.
The Mg-BA driver, developed with a novel surface treatment technology, attains even greater rigidity by infusing a ceramic layer into the magnesium material, making it the thinnest diaphragm for BA drivers in the world as of December 1, 2019.
This manufacturing method not only extends high-frequency playback but also maximizes the "high damping" property of magnesium, reducing the specific metallic resonances that can hinder audio reproduction. This results in a smoother, more natural, and fatigue-free sound.
