64 Audio launches A4s 4-Driver custom IEM

A4 becomes 64 Audio’s second-ever hybrid custom in-ear monitor.

64 Audio has launched the A4s 4-driver custom in-ear monitor, the firm’s second hybrid custom IEM.

“The A4s is a complete redesign of our four driver platform that is elevated by a dynamic low frequency driver, making it 64 Audio’s second ever hybrid custom IEM,” explained 64 Audio Founder and Chief Sound Designer, Vitaliy Belonozhko. “Along with this major update, inside A4s is our tia technology, LID and our patented apex and 3Dfit technologies. The frequency response, detail, and soundstage capabilities of A4s exceed other audiophile products at almost any price point.”

A4s dynamic driver produced bass is powerful, enveloping, and deep while avoiding being muddy. The mids are revealing and present, contributing to its wide stereo imaging and separation. Its high frequency response toes the line between neutral and detailed balanced enough to mix a record with while offering the extension needed to make a recording come alive.

tia is a technology exclusive to 64 Audio that works by eliminating sound-altering tubes and dampers. Sound produced by the tia system is able to yield a smooth and musical frequency response.

LID is a correctional circuit that presents a flat impedance to the amplifier, resulting in a sound devoid of artificial coloration. Exclusive to 64 Audio, LID ensures a consistent frequency response regardless of the source.

3DFit is a new way of manufacturing custom in-ear monitors that preserves the details of your ear impressions for the most comfortable-fitting IEMs possible.

64 Audio’s patented Air Pressure Exchange (apex) is a pneumatically interactive vent that releases air pressure in a sealed ear canal. This venting alleviates listener fatigue and opens the soundstage.

Unlike competitor venting solutions, apex preserves the bass frequencies and produces a more open soundstage, which helps the listener distinguish individual instruments. 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.
