VANCOUVER, WA – 64 Audio, providers of custom and universal fit in-ear monitors, has been awarded its first patent. U.S. Patent #10,441,470 has been issued for the company’s apex (air pressure exchange) technology, which is incorporated into every 64 Audio IEM.

“The team and I at 64 Audio are always looking to bring forth technologies that tangibly benefit our customers, and apex is a perfect example,” explained Vitaliy Belonozhko, 64 Audio founder and chief sound designer. “We are so excited to secure this patent and further position 64 Audio as an industry leader in not only providing a premium audio experience, but also helping protect the hearing of our customers.”

Underscoring 64 Audio’s drive to innovate, apex, or Air Pressure Exchange, is a pneumatically interactive vent that releases air pressure in a sealed ear canal. This venting alleviates listener fatigue and opens the soundstage. Apex comes in two variations, m15 and m20, depending on the model purchased. All of 64 Audio’s current IEMs feature apex technology (tia Trió, Fourté, and Fourté Noir models contain an internal version of the apex module to preserve the tia acoustic chambers).

Unlike competitor venting solutions, apex preserves the bass frequencies and produces a more open soundstage, which helps the listener distinguish individual instruments. Ultimately, artists are better able to follow their mixes and execute the best performance possible.

The apex module is also engineered with features to prevent vent-clogging and wind noise. Its compact and durable construction is virtually maintenance-free, designed for the most demanding users.

From studio to stage to sophisticated home audio environments, 64 Audio has created the industry’s most innovative universal and custom-built in-ear monitors available to date. Founded by Vitaliy Belonozhko in 2010, a sound engineer who has been working with musicians and production companies for nearly two decades, he discovered the advantages of IEMs over traditional floor “wedges” and recognized that a better solution to in-ear monitoring was needed. Today, 64 Audio supplies products worldwide to some of the best-known musicians, singers, and engineers in the world, as well as discerning audiophiles who demand nothing but the best sound reproduction from their systems. With new and unrivaled technologies such as apex, LID, and tia and 3D-Fit, 64 Audio excels in challenging traditional earphone designs to bring-to-market unique and innovative audio products.
