Custom In-Ear Monitors (CIEMs) are high-precision earphones originally designed as a monitoring solution for live musical performances, replacing large format speakers known as floor monitors. CIEMs are now also used for studio performances, mixing/mastering, personal listening and even gaming. 64 Audio makes nine CIEM models ranging from 2-18 drivers per side which cost between $499-$2,999. 

Our goal with the whole product range is to offer the best possible sounding monitor at each price point. Regardless of driver-count we aim to get the most out of each component to produce our balanced, accurate and musical CIEMs. All of our models reflect that signature sound, and with the increase of drivers and cost you get increased fidelity and resolution.
