64 Audio – Fourté

The pinnacle of IEM technologies

64 Audio – Fourté is the apex of portable in-ear innovation, taking full advantage of everything 64 audio has learned up to this point in planning world-class in-ear monitors, designed for professional artists as well as audiophiles.

Fourté has the most extensive soundstage amongst any in-ear monitors, making it the culminate choice for audiophiles looking for pinpoint accurate accuracy, with top-tier three-dimensional sound.

Fourté highlights 64’s three-part tia™ framework housed in an ergonomic shell design, machined from a solid piece of aluminum and topped with rich, copper patina faceplates.

64 Audio – Fourté Tia technology

Firstly, With a tubeless design, resonances are reduced to a minimum level. Such helps offer the most accurate and straightforward sound signature.

The tia framework is comprised of three major components: open adjusted armature tia drivers. The tia single-bore structure, and tia acoustic chambers. The Fourté highlights two major components of the tia framework: the tia driver and the tia single-bore design.

Tia Driver features an open balanced armature speaker design, which aims at resolution. Transparency while being extremely realistic in sound production.

The open balanced armature design allows the diaphragm to be not obstructed, giving its full swing and reducing resonance. It is enabling the sound to be traveling much more naturally and transparently to your ears.

Letting one single bore rules

Secondly, This is a big leap toward resonance reduction. The huge bore itself serves as a sound chamber that shapes the output. Helping the drivers to deliver a more linear and coherent frequency response.

The minimal sound pathway within allows the high-frequency energy to retained.  So well that you can hear tons of details in the very extended and smooth treble.

Apex venting technology

In the conclusion, You may have experienced pressure sealed inside your ear. When wearing a custom monitor or a high-grade earphone, but this does not happen on the fourth.

The design alleviates the listener’s fatigue by guiding away air pressure that trapped in the ear when you wear the earphones.

This design allows musicians and enthusiasts to listen more comfortably for long durations and without any fatigue caused by the closed seal.

Lastly, Custom in-ear monitors provide enhanced isolation and help musicians hear their mix more clearly. Even at lower volume levels than studio monitors or earbuds.

Apex lowers the decibel levels while retaining the sound qualities and clarity. So If you play on stage you can connect to the audience while protecting your hearing.
