Eighteen precision balanced armature drivers
64 Audio at Audio46
Designed for professionals on stage and in the studio, the A18s is the final authority on flagship in-ear monitors that boast elite performance. Based on the world’s first 18-driver earphone, it provides the clarity and precision necessary for sound engineering with the warmth, power, and headroom demanded by musicians taking the stage.
Now including LID technology the A18s is our most capable and versatile in-ear monitor ever created.
Exclusive technologies that challenge traditional in-ear monitor designs to give you the absolute best listening experience
A18s features the following unique technology:
A tubeless design that reduces resonance for a transparent and lifelike sound signature.
Only from 64 Audio, apex alleviates listener fatigue by releasing air pressure sealed in the ear canal. This venting enables musicians and music enthusiasts to listen more comfortably for longer.
Apex, or Air Pressure Exchange, is a pneumatically interactive vent that releases air pressure from a sealed ear canal. Apex comes in two variations, m15 (-15dB) and m20 (-20dB).
Alleviate Listener Fatigue
When you seal a miniature speaker in an ear canal, the air inside becomes trapped. Apex relieves this air pressure, allowing the eardrum to move naturally, so you can comfortably listen longer.
Extend The Soundstage
Freely moving air extends the soundstage and provides a more natural listening experience. It also preserves bass frequencies and helps the listener distinguish individual instruments.
Hear Your Audience
Custom in-ear monitors provide amazing isolation and help you hear your mix more clearly and at lower volumes than a wedge monitor or earbuds. Apex lowers decibel levels while preserving the clarity of the sounds around you, so artists on stage can connect with their audience while protecting their hearing.
Preserves the detail of your ear impressions using a new process of digital rendering and 3D printing for the most comfortable custom in-ear monitors available.
Our 3D-Fit technology preserves the detail of your ear impressions using a new process of digital rendering and 3D printing. Compared to conventional wax-dip molding, this process reduces distortion in the impression for the most precise and comfortable custom in-ear monitors available.
A great fitting pair of custom in-ear monitors begins with a quality set of ear impressions. Each impression is digitally scanned and refined by our technicians to preserve each detail for a perfect fit.
Final shells are printed using our state-of-the-art 3D printer using a hypoallergenic, hard acrylic. The colors and materials we use have been specifically chosen for longevity and durability. These materials also allow the digital renderings to maintain their detail for optimal comfort.
Once shells are printed, our production team assembles the remaining components by hand. All 64 Audio Custom In-Ear Monitors are customizable and hand-built from your unique ear impressions. Wearing a custom-fit earphone helps isolate external noise and offers a more comfortable listening experience compared to most universal earphones.
Enables a consistent, reliable sound regardless of audio source.
LID, or Linear Impedance Design, enables a consistent, reliable sound regardless of what source. This proprietary circuit corrects the non-linear impedances of the drivers, restoring proper interaction with the source and preserving the desired sound signature.
Whether you're a musician plugging into a variety of gear at different gigs or studios, or an audiophile listening from low-impedance sources, LID ensures your IEMs are delivering the desired sound signature consistently.
And like all our IEMs, this model can be used with a wide range of personal audio devices as well as all hard-wired and wireless monitor systems.
