The 64 AUDIO U12 Universal-Fit earphones are the pinnacle of personal audio. They offer a sleek, ergonomic design, and premium sound quality.

The U12 is the culmination of over 7 years of IEM design and are built on the revolutionary apex™ technology. Because of this technology and its effect on the human ear, they offer an unmatched listening experience with silky highs, a luscious mid-range and deep, controlled bass.

12 drivers work in perfect harmony to deliver a remarkably rich and immersive sound with impeccable spacial imaging. The U12 will reveal undiscovered layers of sounds that you couldn't hear with conventional IEM's. While there are other 12-driver products on the market, nothing comes close to the transparency, agility and power of the U12.

This product is ideal for Stage or Studio musicians and the most discerning Audiophiles.

Like all 64 AUDIO universal-fit products, the U12 earphones are inherently noise cancelling and are designed to work well with a wide range of personal audio devices as well as all Personal Monitoring Systems.

What is apex™?

When you seal a miniature speaker in an ear canal, the air inside becomes trapped. As the speaker produces sound it moves the air and causes the ear drum to work excessively. The pressure exerted on the ear drum causes ear fatigue, also known as listener fatigue.

By way of a pneumatically interactive vent the apexTM Technology (Air Pressure Exchange) relieves this pressure. With apex the sound is also dramatically improved across the spectrum, the soundstage is more expansive than ever before, and the technology is versatile allowing for a selection of isolation levels — all while minimizing ear fatigue.
