Description
A12t
Twelve Driver Custom In-Ear Monitor
Custom-Fit, Custom-Look, Custom-Made
An ultimate in-ear monitor for professionals onstage or in the studio, with renowned resolution and a lovable sound signature that delights even the most discerning listeners.
The A12t does it all. A studio reference monitor designed to withstand the rigors of live performance monitoring, but also a popular choice for everyday listeners seeking the best. Balanced, natural, and musical while being articulate in the upper-mids and punchy in the lows.
Offering reference-level detail, this CIEM is among the best for multi-instrumentalists, engineers, sound monitors, and audiophiles.
Bay Bloor Radio in Toronto makes custom in-ear monitors easy:
1. Decide and customize.
At our store in downtown Toronto, we have "universal" versions of 64 Audio's custom IEMs available for testing. While they won't perfectly conform to your ears or have the insertion depth like the final product, they'll give you an idea of sound signature so you can make the best decision for your tastes and needs. Our expert staff can also guide you through customization options and accessories.
2. Make impressions.
Once your order is in, you'll need to have impressions taken of your inner ears. To make things easy, we've partnered with a nearby audiologist familiar with 64 Audio's specifications. Our $49 CAD custom shipping package takes care of international shipping in both directions, and covers all cross-border import fees and customs brokerage — no need to worry about surprise charges upon delivery.
3. In production.
Each 64 Audio CIEM is hand built by highly specialized technicians in Vancouver, Washington. They will scan your impressions to perfectly recreate the intricacies of your ear shape, mapped to fit all internal components, then printed into 3D shells made from hypoallergenic acrylic. Once drivers are installed and tested by hand, your custom faceplate is the final touch to a truly one-of-a-kind earphone.
A12t is also available in a universal version, U12t.
The best-selling universal IEM from 64 Audio, U12t carries the same driver configuration in an elevated solid aluminum shell. It features upgraded packaging and accessories, including all three sets of Apex modules, a premium cable, multiple eartip styles and sizes for fit and sound flexibility, and leatherette case.
As UIEMs are not customized to each wearer, multiple people can enjoy the earphones throughout their lifespan. They are also available for purchase with minimal to no wait time.
SOUND
A12t is balanced, accurate and extremely musical. What do we mean by musical? It’s our best way of articulating an IEM’s ability to present a mix in an engaging yet non-distracting way; getting enveloped into a song or performance while trusting that what you’re hearing is correct.
Lows are punchy, with more than enough headroom to satisfy drummers and bass players. The low-end has enough amplitude to spare in case you want to use A12t with one of the other apex™ modules, that will slightly reduce its impact.
Low-mids present just enough “body” without tipping the sound into being “warm,” unlike A18s which is on the slightly warmer end in this regard. Mids and high-mids are articulate without being too detailed; this is where A12t and A18t differ the most. Highs are beautifully extended and airy because of the tia™ driver that resides in the very tip of the canal.
The soundstage, which is the perceived width of the stereo field, is in-line with the rest of our reference-grade IEMs. Apex™ and tia™ both contribute to our IEMs’ impressively wide imaging compared to other IEMs and headphones. This distinctive feature surrounds the listener more naturally and improves instrument separation when monitoring live; like your pan nobs are able to rotate further to the left and right.
"I have had reason to finish some mixes just on my A12ts with no access to my normal monitors. I felt really good about the mixes, and became unaware that I was wearing in-ears, just in the flow of mixing. Hearing everything I needed to hear."
– Ainslie Grosser (Grammy winning mixing engineer)
– Ainslie Grosser (Grammy winning mixing engineer)
"The sound across the spectrum is spacious, smooth, and not strident. When a mix is right, I can hear every single detail with the A12t, and all sounds are three-dimensional to my ears. There are elements in songs that I’ve heard all of my life that I was totally unaware of until I tried these IEMs."
– Lars Fox (Grammy nominated music editor)

CUSTOMIZATION
Along with a number of acrylic shell options, there are dozens of faceplate colours and materials, which translates to hundreds of unique combinations. On top of all those options, you can even add custom artwork to make your IEMs truly one-of-a-kind. Left and right sides can be configured separately. Costs vary based on the options selected.
Also offered are a selection of connector types and cable. 2-pin connectors are an industry standard socket for IEMs, opening up more aftermarket cable options, ideal for audiophiles looking for flexibility. IPX (sometimes referred to as T2) connectors are moisture resistant snap-in sockets made by Estron A/S, which have proven to be a most robust choice for live music performers. Along with the socket you can choose between two cable colours and lengths.
TECHNOLOGY
3D-Fit for Custom IEMs
Exclusive 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. All of our Custom In-Ear Monitors and Custom Earplugs are crafted using this process.
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.
Tubeless In-Ear Audio
64 Audio's tia is a patented IEM design methodology that aims to reduce unwanted resonance and distortion for a transparent and lifelike sound signature. A12t features two major elements of the tia system:
The tia driver is an open balanced armature speaker design that brings new meaning to resolution and transparency. It delivers airy, crisp, and microdetailed upper frequencies with characteristics not often found in a headphone or in-ear monitor. By opening a balanced armature, the diaphragm becomes fully unobstructed, unleashing the sound potential of the driver. This eliminates a lot of the vibrations and resonances that are inherent in conventional, closed balanced armature designs. With this new method of producing and delivering sound to the ear, conventional sound tubes and dampers are no longer necessary.
The tia single-bore design is a huge leap forward 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. Because of the extremely short sound path of the tia high driver, a remarkable high-frequency extension and smoothness is achieved. The large single bore also helps prevent clogging of the tip and obstruction of sound.
Air Pressure Exchange
Apex is a patented vent that releases air pressure in a sealed ear canal all while retaining a level of isolation; this venting alleviates listener fatigue and allows for a much more realistic soundstage.
When you seal a miniature speaker in an ear canal, the air inside becomes trapped. As the speaker produces sound, it moves the air and causes the eardrum to work excessively. The pneumatic pressure exerted on the eardrum causes ear fatigue. Apex relieves this pressure, allowing the eardrum to move naturally, so you can comfortably listen longer.
Apex enables air to move freely in the ear canal, which extends the perceived soundstage and allows for a more natural listening experience. Everything from inserting, wearing, and removing the IEMs becomes a much more natural and painless process.
Apex is implemented in A12t via interchangeable modules, so you can quickly switch between different levels of isolation and sound signatures. Although the modules technically only affect the low frequencies, this psychoacoustically affects your perception of the whole frequency range.
- The m20 module (included and fitted by default, -20dB noise isolation) offers a pronounced sub-bass shelf with the type of isolation you'd expect from a conventional IEM, minus the ear fatigue.
- The m15 module (included, -15dB noise isolation) is a popular choice for maintaining a smooth and warm sound, while allowing you to hear some more of your surroundings.
- The mX module (sold separately, -10dB noise isolation) lowers the bass quantity for a more typical "neutral" listen, while opening up the soundstage and reducing isolation even further.
Linear Impedance Design
Smartphones, body packs, amps, and DAPs produce audio with different output impedances. The interaction of the earphone impedance curve with the sources may result in the same IEM sounding different with different sources.
LID is a proprietary circuit that corrects the non-linear impedances of the multiple driver-sets that comprise this twelve-driver IEM, restoring proper interaction with the source and preserving the desired sound signature, so you can enjoy the same sound reliably across sources.

Due to their bespoke nature, there are no returns on custom earphones once ordered.
When you purchase from Bay Bloor Radio, our expert staff will assist with each step of the custom fit process. Universal demo earphones are available in-store to assist you in selecting the right model.
Because of the many variables involved in creating a custom product, sometimes a fit adjustment may be needed. For this reason, 64 Audio offers a 30 Day Fit Guarantee to ensure that your IEMs fit comfortably and retain a proper seal.
If a fit adjustment is required 64 Audio will need the IEMs sent back for the shells to either be shaved down or built up in the specified problem areas. 64 Audio may, at their discretion, rebuild your IEMs for which new impressions may be required. In some cases, prior to starting the rebuild process, empty test shells may be sent to you to determine if the adjustments have corrected the fit issue. The cost of two-way international shipping, import, and brokerage for all refits is $49 + tax. Customers may alternatively choose to ship items back to 64 Audio at their own expense. Cosmetic properties such as the height of the IEMs due to space required for drivers, cable connectors or faceplates are not considered a defect and would not be covered under the fit guarantee.
