A3t is 64 Audio’s newest three driver custom fit in-ear monitor. In typical 64 Audio fashion we continue to make our revolutionary technology more and more accessible. With A3t our Tia technology is available at a new lower price point, along with LID and our patented Apex and 3Dfit tech. The goal with A3t was simple: make a reference monitor that rivals products more than 5x its price, this simple yet powerful arrangement of balanced armature drivers and crossover components achieves that perfectly. This is a perfect tool for any audio engineer or musician looking for a neutral, balanced and musical reference monitor for live and recorded performance.

Technology
Exclusive technologies that challenge traditional in-ear monitor designs to give you the absolute best listening experience.

tia™
A tubeless design that reduces resonance for a transparent and lifelike sound signature.

apex™
This pneumatically interactive vent relieves air pressure in a sealed ear canal, alleviating listener fatigue and opening the soundstage.

LID™
LID is a correctional circuit that presents a flat impedance to the amplifier, resulting in a sound devoid of artificial coloration.

3DFIT
A new way of manufacturing custom in-ear monitors preserves the details of your ear impressions for the most comfortable-fitting IEMs possible.
