The Mg IEM utilizes a high magnesium content alloy (96% Mg) for the diaphragm material. All components inside our IEMs was 100% designed and tooled in-house, resulting a totally unique product.

  • The sonic signature of the Mg IEM is relatively neutral but with a brighter top end than our Be unit. Many people prefer this sound for use in noisier environments.

  • All our IEMs feature polycarbonate bodies for high strength and zero resonance, custom front-and-rear tuned volumes, MIM logo caps, butyl rubber strain reliefs, and N48H grade magnets.
