custom IEM
Realization of unprecedented high quality sound. Extended high frequency reproduction by maximizing the weight reduction of the vibration system. Newly developed special surface treatment technology reduces noise components that interfere with sound reproduction by increasing rigidity while maintaining high vibration absorption.
Characteristics
Jointly developed by Onkyo and FiTEaR
BA driver with the world's thinnest* magnesium diaphragm

Unprecedented High-Quality Sound

Newly developed special surface treatment technology reduces noise components that interfere with sound source reproduction by increasing rigidity while maintaining high vibration absorption.
*As of December 2023, according to Onkyo research.
Magnesium is the lightest practical metal material, and the Mg-BA driver uses a diaphragm with a ceramic layer that penetrates to the inside of the magnesium material using special surface treatment technology, which also achieves high rigidity. In addition to extending high frequency reproduction, the material's unique high vibration absorption properties reduce noise components that interfere with sound source reproduction, resulting in smoother and more faithful reproduction of the original sound.
Lightweight
Lightest weight of all practical metals
High internal loss
Highest internal loss of any practical metal
High specific modulus (high propagation velocity)
Very high specific elastic modulus compared to other materials
Magnesium is a good material for high-resolution
Performance comparison with conventional BA driver
Although it is said that BA drivers are not good at low-frequency reproduction due to their structure, the newly developed highly rigid magnesium diaphragm with special surface treatment has a lower distortion rate than the conventional aluminum diaphragm and realizes a solid core of bass sound with no loss of low-frequency sound even at high input.
