Moved By Mg

The Mg (Magnesium) IEM utilizes a high magnesium content alloy (96% pure) for the diaphragm material. Magnesium may be the lowest cost IEM in our stable but it by no means a slouch, earning the coveted Top Pick from Stereo Review. High performance, affordable price, extreme comfort make a potent combination.

Magnesium is the least dense of all stable metals. Magnesium is also very high on the stiffness-to-weight ratio, and that is why it’s used in automotive and aerospace applications. These two properties result in a highly efficient, low distortion transducer foundation.

What’s New With the Mg?

We’ve done a few great changes to Mg – and the whole line – to improve performance and user experience. This starts with a new material for the entire enclosure. We worked for 3 years with Eastman Chemicals, one of the largest plastics companies in the world, to research, develop, and quantify new polymers for acoustic applications.

Our research led us to a specific blend of their Tritan™ copolyester. This material proved to be not just rigid, but acoustically dead with lower energy storage and transmission than the polycarbonate we were using. Stray resonance and noise is lowered even more.

We also refined the external and internal geometry to make it more anti-resonant, so clarity is increased alongside the improvements of the materials used. The result is the most stable, lowest resonant IEM enclosure ever made. All with the lowest weight enclosure possible.

I See a Detachable Cable? What’s That About?

We have also developed our own 2.5mm jack: the IDEEL connector. This connector is the world’s smallest 2.5mm jack, measuring just 3.6mm across, and a tiny 9.5mm mounting depth. This jack allows us to use the very robust 2.5mm TS plug in our tiny IEMs. No more delicate MMCX or difficult 2 pin plastic connectors needed.
