The Be IEM has a 100% pure beryllium foil  diaphragm with a bonded PEEK surround. All components inside our IEMs was 100% designed and tooled in-house, resulting a totally unique product.

The sonic signature of the Be IEM is quite neutral.  Strong, even bass with a clear but balanced top end, the Be has vanishingly low THD and one of the best waterfall plots ever seen.

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.
