The 64 AUDIO U8 universal-fit earphones are premium, quad-low-driver "powerhouses".

They are built on the revolutionary apex™ technology and feature eight miniature drivers per ear. Because of the apex™ technology and its effect on the human ear, they offer a listening experience that simply cannot be matched by conventional IEMs.

Special attention was put on enhancing the bass in such a way that it does not "overpower" the rest of the frequencies. The result is an incredibly powerful, dynamic and hard-hitting bass that allows the mid-range and high frequencies to stay clear and vibrant.

This product is designed for bassists, drummers, keyboardists and anyone seeking a warm and immersive sound.

Like all 64 AUDIO universal-fit products, the U8 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.
