Are Diamonds An Audiophile’s Best Friend? Periodic Audio Hopes So.

Periodic Audio, a company known for their Periodic Element themed earphones, is incorporating a very precious element in their new flagship IEM. That element is Carbon, which is used to create the lab-grown diamonds that coat the diaphragms in their new earphones.

Carbon is also the name of Periodic Audio’s new product and they claim by using a diamond coating on the drivers, their IEMs achieve very low levels of distortion even at very high sound levels. This, in turn, is supposed to provide a very fast, detailed and dynamic listening experience.

The Carbon (C) IEM is available now for $399 on the Periodic Audio website, and you can also see it on display at the Fifth Annual CanJam Show taking place June 22-23 in Irvine, CA.

Diamond ’ducers, because Music Is Forever-Periodic Audio announces new Carbon flagship IEM now shipping

June 2019—Los Angeles, CA —Periodic Audio is thrilled to launch its new flagship during the Fifth Annual CanJam Show June 22-23. Known for its use of periodic elements, Periodic Audio pushes the envelope with the new Carbon (C) IEMs, featuring diaphragms made from lab-grown diamonds. Carbon’s design provides the ultimate statement in resolution—with incredibly low distortion—below that of any other IEM on the market today.  

The C IEM uses an 8-micron-thick (8 millionths of a meter) layer of lab-grown diamond on Periodic Audio’s proprietary high-temperature polymer substrate. All components inside this IEM are designed and tooled 100% in-house, to result in an entirely unique product.

“Carbon sets a new bar for low distortion in a headphone/in-ear product with less than 0.1% total harmonic distortion (THD), even at sound-pressure levels (SPLs) at or above 100dB,” said Dan Wiggins, cofounder of Periodic Audio. “Specs aside, the clarity and resolution of this IEM let you hear things you’ve never heard before. It adds nothing to the sound while revealing everything. With a frequency response between our Be and Ti IEMs, C results in a fun, dynamic, highly resolving listening experience.”

The sonic signature of the C IEM is an interesting mix of the signatures of the Ti and Be IEMs, with the enhanced bass response of Ti but the high-end extension of Be. Carbon is well suited to electronic music, or anything with fast transients and extremely wide frequency response. By a fairly wide margin, C has the lowest THD of any IEM Periodic Audio has produced.

The Carbon’s sleek, all-black construction creates a low-key, stealthy look that delivers micro- and macro-dynamics for an unrivaled listening experience. Like all Periodic Audio IEMs, C features a polycarbonate body for high strength and zero resonance, custom front-and-rear tuned volumes, MIM logo caps, butyl-rubber strain reliefs, and N48H-grade magnets.

Finally, to ensure a proper fit while preserving the highest sound quality, Periodic Audio has design its own eartips*, creating three shapes that together cover 95% of all ear canals. For all other accessory needs, a gold-plated, ¼” jack and airplane adapters are included, along with a stylish carrying tin. Like all Periodic Audio IEMs, Carbon is covered by the company’s industry-leading five-year warranty, and is proudly conceived, engineered, and assembled in the USA.

Fun fact:

It takes about 30 hours in the chamber to grow the diamond. Periodic Audio grows 10,000 diaphragms at a time, with about a 60% pass rate. They will discard over 21 carats of diamond waste with each run!
