Custom IEM Model Overview
64 Audio makes nine custom in-ear monitor (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 components for balanced, accurate and musical IEMs. All of our models reflect that signature sound, and with the increase of drivers and cost you get increased fidelity/resolution.

A6t is 64 Audio’s most popular custom in-ear monitor (CIEM). The six drivers in each earpiece are crossed over at three points making A6t a 4-way system just like most of our CIEMs. Two balanced armature (BA) drivers cover low frequencies, another two for low-mid, and then a single BA for high mids with our patented tia driver extending to through the high-frequency band. A6t draws from the sonic palette of A12t; boasting the same groundbreaking technology as our flagship IEMs.
64 Audio’s six-driver designs have historically garnered a reputation of their own starting with our V6 and V6-Stage models, which were the first to hit that sweet spot of capability and presence. Those early six driver models shaped the house sound of 64 Audio and the sound of our entire current lineup can be traced back to those early models. With such great shoes to fill A6t replaced our A6 model in mid 2018 by adding our patented tia driver and single sound bore and making it a 4-way system similar to our other high-driver count models. Not only does A6t live up to the legendary reputation of previous 64 Audio six driver CIEMs, it out-competes IEMs with twice the driver count and price.
A6t is an ideal representation of 64 Audio’s balanced, natural, and musical sound signature. Similar to our A3t but with more bass capability and separation. One of its most distinct characteristics is its mid-range imaging. A6t really brings forward those instruments that sit heavily in the mids like vocals, electric guitars, and piano. The broad appeal of A6t is not only its middle of the range price point but also the ability to cover almost any monitoring need with ease. The forward nature of the mid-range is great for vocalists and guitar players, the low-end rumble can reproduce the deepest bass guitar tones, and the low-mid punch makes any drum mix really cut through.
Like all 64 Audio CIEMs that feature our tia high frequency driver A6t produces airy highs with smooth extension. A6t presents that high frequency response without getting too detailed or overly hifi sounding making it one of the most capable monitoring tools available for professional musicians.
To me it’s a very easy listening in-ear. Everything I’ve put this through, there’s not like a harsh high end, the mids aren’t scooped low…I’ve listened to drum mixes that I did through these, you can hear if I’m using a maple stick or a hickory stick, which is kind of insane. The articulation on the cymbals is gorgeous. There’s a really nice shimmer to it but it’s not zingy if that makes sense.Carter McLean (Drummer for THE LION KING on Broadway)
I’m absolutely in LOVE with my new in-ears! If you’re a veteran or new to singing, I would highly recommend all singers get some sort of in ear monitorsLauren Babic
One day at sound check I used the six driver, A6t, and they sounded incredible. They were amazing, they were exactly how my guitar sounded over the PA out front. This made me play better because I sounded better.Ryan ‘Fluff’ Bruce (Riffs, Beards & Gear)
Custom-Fit, Custom-Look, & Custom-Made
Each 64 Audio CIEM is hand built in Vancouver Washington by highly specialized technicians.
Ear impressions are first trimmed and scanned into our 3D detailing software. Our patented 3Dfit technology is used to perfectly recreate the intricacies of your ear shape. We virtually accommodate for all of the internal components before 3D printing with hypoallergenic acrylic material.
Once the shell is printed our assemblers insert the pre-soldered driver packs associated with the model of the IEM.
The assembled CIEMs are later completed with a faceplate. Along with the 5 shell options, there are dozens of faceplate colors and materials which translates to hundreds of variations. On top of all of those options we’re also able to use custom artwork to make your IEMs truly one-of-a-kind.

Air Pressure Exchange (Apex) is a patented vent that releases air pressure in a sealed ear canal. In addition to relieving air pressure, it also maintains standard IEM levels of noise isolation. The attenuation of ambient noise and pressure relief enables musicians and music enthusiasts to listen more comfortably for longer. This venting alleviates listener fatigue and allows for a much more realistic soundstage. Apex comes in three module variations available for A6t: mX, m15 and m20.
Tubeless In-Ear Audio (tia) is a patented IEM design methodology that aims to reduce unwanted resonance and distortion for a transparent and lifelike sound signature. The tia system is comprised of three major elements: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers. A6t features two major elements of the tia system: the tia driver and the tia single-bore design.
3D-Fit preserves the detail of your ear impressions using a new process of digital rendering and 3D-printing. The patented process of incorporating acoustical tuning features within an IEM’s shell allows for designs that would otherwise be impossible to build using traditional methods. We incorporate these advanced and uniquely complex features into the shell in order to manipulate the audio produced by the IEM. This process also reduces distortion in the impression for the most precise and comfortable custom in-ear monitors available.
Linear Impedance Design (LID) is a patented circuit that corrects the non-linear electrical resistance of the multiple driver-sets comprising this 6 driver IEM. Varying source amplifier output impedance in devices like smartphones, body packs, DAC/amps, and DAPs typically results in varying frequency response across them, depending on the increase in resistance. Restoring proper interaction with the source and preserving the desired sound signature enables a consistent reliable sound.
