Applied Material Properties: Be

Beryllium is among the least dense stable metals, but also has among the highest Young’s modulus values (a ratio of the stiffness) and speed of sound. 

This results in high efficiency and extremely low distortion as the diaphragm does not bend on its own, moves homogeneously, and dissipates internal energy very well.

This rare combination of performance attributes is what endows the Be IEM’s with their freakish ability to compete with the best Beryllium transducer-based headphones on the market, at any price.

Still not sure that this IEM is for you?  Then use our amazing Select-A-Tron to guide your IEM choice!

Is there a measurement that demonstrates clarity?

Yes! A “waterfall plot” is one of the measurements our team performs when designing transducers, and acoustic systems in general.

Listening to a system that has a poor waterfall plot measurement is like wearing the wrong prescription glasses. Everything is out of focus.

Conversely, a system with a fantastic waterfall plot measurement is like 20/20 vision for your ears. Tremendous clarity.

Our proprietary 10mm Beryllium transducer has insane waterfall plot measurements:

How does a good waterfall plot improve the overall sound experience?

A favorable waterfall plot has a direct correlation with the perception of how ‘real’ something sounds, and the systems ability to accurately render the depth and breadth of a recording.
