The A3t is 64 Audio’s newest three driver custom fit in-ear monitor and it packs a punch! 

It was designed to make their groundbreaking technology more accessible for all. The A3t features Tubeless In-Ear Audio (Tia) technology at a new lower price point for crystal clear highs, along with LID and patented Apex tech for a wide, detailed and full sound experience for all musicians. 

The aim of the A3t was simple: to make a reference monitor that rivals products more than 5x its price, we can happily say that it does! 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. We love these IEMs.
