Our versatile, three-driver custom in-ear monitor provides impressive clarity and warmth for any instrument or genre. The A3e is ideal for vocalists, drummers, or any single-instrumentalists looking for a professional IEM to use onstage. This is a great option for artists seeking a detailed soundstage, neutral tuning, and a transparent and musical sound.

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

apex™
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).

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.

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.

LID™
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.

3DFIT™

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 moulding, 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 colours 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.
