Periodic Audio Be Beryllium

Refurbished unit in excellent condition repackaged with original accessories or accessories from compatible models and brands.

Periodic Audio goes back to the basic elements in the creation of the perfect earphone sound. Every part integrated into Periodic Audio earphones plays an important role in the audio chain. Periodic Audio has been extensively experimenting with different shapes and materials of the diaphragm to achieve different sonic signatures.

All earphones in the Periodic Audio line-up are crafted from the ground up and every element is designed and tooled entirely by Periodic Audio. This version has been fitted with a Beryllium diaphragm made from 99% pure beryllium foil that provides a relatively neutral sonic signature with even bass and clear but balanced top-end and vanishingly low distortion.

As every part of the Periodic Audio Beryllium earphones has it's unique purpose, the housings have been precision moulded from an anti-resonant and highly durable polycarbonate. The internal body shape has been carefully configured to distribute the acoustic pressure evenly and utilises every bit of space for the absolute listening experience.
