Periodic Audio Mg (Magnesium) In-ear monitors w/ 96% magnesium alloy diaphragm

  • Sale
  • $ 99

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

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

All Periodic Audio in-ear monitors 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.
