These are CUSTOM earphones from 64 Audio. Current lead time is 4 weeks from the time 64 Audio receives the impressions. You need to visit an audiologist to get your ear impressions made first. By purchasing from Bloom, you receive our attentive lifetime support. We'll assist during each step of the process. Keep in mind, all custom earphones orders are final. Feel free to Call, Email, or Message us if you have any questions about ordering custom IEMs.
From 64 Audio
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.
A18s features the following unique technology:Tia
The tia system is comprised of three major elements: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers. All our Custom In-Ear Monitors with tia feature two major elements of the tia system: the tia driver and the tia single-bore design.
An open balanced armature speaker design for realistic resolution and transparency. By opening a balanced armature, the diaphragm becomes fully unobstructed, reducing resonance in the IEM and allowing sound to travel more naturally to the ear.
Tia Single Bore
A huge advancement in eliminating unwanted tube resonance. The large bore itself serves as a sound-shaping chamber and aids the tia high driver in delivering a linear and coherent frequency response. The short sound path provides remarkable high-frequency extension and smoothness. The large single bore also allows for easier maintenance.
Apex, or Air Pressure Exchange, is a pneumatically interactive vent that releases air pressure in a sealed in the 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.
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 preserves 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 allows 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.
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.

We're proud to offer the full lines of custom in-ear monitors from our friends at 64 Audio, Campfire Audio, Empire Ears, and Noble Audio. But before buying custom IEMs, you would need to get impressions made by an audiologist. Here are the instructions from each:
Once you have your impressions, you're good to go and ready to order through us. So now the obvious question: why should you order your custom IEMs through Bloom and not just direct from the manufacturer? The answer is simple: lifetime support and our white glove service through the whole step of the process. So yeah, you pay the same price with us as you would direct, but you also get us to personally guide you during the whole process and get our support for as long as you have your custom IEMs. Seems like a no brainer? For sure.
