Designed for professionals on stage and in the studio, the 64 Audio A18s custom earphones are 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 the most capable and versatile in-ear monitor ever created by 64 Audio.
64 Audio took their flagship 18 driver in-ear monitor A18t and added a new driver and crossover to sound bigger, richer, and clearer at high volumes. With a more sophisticated electronic crossover network, the A18s has the headroom to achieve optimal clarity without distortion. Musicians will be pleased with its warm, detailed, and spacious sound that keeps up with the most demanding performance. The punch, power, and precision of the A18s makes it the ultimate in-ear monitor for every kind of artist, instrument, or genre of music.
A18s comes equipped with LID, an exclusive 64 Audio technology that provides a consistent sound signature no matter what source you’re plugged into. This consistency gives you the advantage of picking up right where you left off without redoing changes or course-correcting your workflow. Whether you’re mixing in the studio or reviewing tracks on a laptop before a gig, the A18s remains reliable and true to its sound signature from source to source.
Elite audio performance.
Tia®
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. A18s features two major elements of the tia system: the tia driver and the tia single-bore design.
Apex®
Air Pressure Exchange (Apex) is a patented vent that releases air pressure in a sealed ear canal all while retaining standard IEM levels of isolation; enabling 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 with two module variations for the A18s: m15 and m20
LID®
Linear Impedance Design (LID) is a patented circuit that corrects the non-linear electrical resistance of the multiple driver-sets comprising this 18 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.
30 Day Fit Guarantee
Because of the many variables involved in creating a custom product, sometimes a fit adjustment is needed. 64 Audio offers a 30 Day Fit Guarantee (on approved impressions) to ensure that your IEMs fit comfortably and retain a proper seal. 64 Audio requires that you notify customer service within 30 days of receiving your IEMs to be covered by the 30 Day Fit Guarantee.
3D-Fit®
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. All 64 Audio Custom In-Ear Monitors and Custom Earplugs are crafted using this process.
