Periodic Audio Beryllium V3 Be
Periodic Audio Beryllium 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. Periodic Audio has taken the absolute earphone experience further with upgrade design offering the same outstanding performance but now with detachable cable and redesigned housing.
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.
Elementary listening.
Beryllium Diaphragm
Beryllium is among the least dense stable metals, but also has among the highest ratio of 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.
Precision Crafted
With precision injection moulded parts the housing is made from highly durable polycarbonate material that provides a rigid material free from vibrational noises. The internal body shape is tuned to distribute the acoustic volume evenly in the front and back of the housing.
Detachable Cable
Equipped with redesigned cable that is detachable and terminated with Periodic Audio's own designed custom 2.5mm connectors. Periodic Audio's own IDEEL (IEM Direct Electrical Engagement Link) connectors are the world’s smallest 2.5mm connectors, measuring just 3.6mm across with a mounting depth of 9.5mm.
Perfect Fit
To further make the sound of the Periodic Audio earphones an audiophile-level listening experience, they are supplied with both silicone and memory foam eartips in different shapes and sizes for true immersive sound performance.
5-Year Warranty
As Periodic Audio are confident with the quality and longevity of their earphones they offer a limited 5-year warranty on parts and labour.
