64 Audio by Bill Newcomer

Hear the music. Hear everything. â&#x201E;¢ | www.64audio.com

Music is not just beautiful sounds in the form of vibrations traveling through air. It is an energy and a language that can heal the soul, turn a rainy day into a feeling of sunshine, and bring to mind the fondest memories of the past. 64 Audio was born out of an inspiration and passion to achieve the deepest emotional connection with the music that we love. Our mission is to reproduce sound in the purest and most unadulterated form, by eliminating any unnatural tones, resonances, and distortions. Thank you for taking this journey with us.

EXCLUSIVE TECHNOLOGIES

RELIABLE SOUND LID is a proprietary circuit that corrects the non-linear impedances of the drivers, restoring proper interaction with the source and preserving the desired sound signature.

PLUG INTO ANY SOURCE 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 mitigates these inconsistencies so you can enjoy the same sound across sources.

ALLEVIATE LISTENER FATIGUE 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 pressure exerted on the eardrum causes ear fatigue, also known as listener fatigue. Apex relieves this pressure, allowing the eardrum to move naturally, so you can comfortably listen longer.

EXTEND THE SOUNDSTAGE Apex enables air to move freely in the ear canal, which extends the soundstage and allows for a more natural listening experience. A more open soundstage also preserves the bass frequencies and helps the listener distinguish individual instruments. Ultimately, artists are better able to follow their mixes and execute the best performance possible.

CHOOSE YOUR ISOLATION There are two levels of isolation provided by apex, -20dB (m20) and -15dB (m15). The m15 module allows for slightly more ambient sound than the m20, and helps temper the bass. Each of our in-ear monitors is built with a speciďŹ c apex module in mind, however our standard external apex modules are designed to be interchangeable, so you can rotate between levels of isolation and sound ďŹ&#x201A;avors. 4

TIA DRIVER The tia driver is an open balanced armature speaker design that brings new meaning to resolution and transparency. By opening a balanced armature, the diaphragm becomes fully unobstructed, eliminating many of the vibrations and resonances that are inherent in conventional, closed balanced armature designs. By delivering sound to the ear in this way, conventional sound tubes and dampers are no longer necessary.

TIA ACOUSTIC CHAMBERS The tia acoustic chambers further shape the sound of the tia drivers, optimizing driver performance by giving them their own space and tuning the drivers without introducing unwanted resonances. Each driver is perfectly matched to its acoustic chamber just like a pair of speakers are tuned to a studio control room, delivering a three-dimensional soundstage unmatched by any other IEM.

TIA SINGLE-BORE Serving as a sound-shaping chamber, the single-bore aids the tia high driver in delivering a linear and coherent frequency response, further eliminating unwanted tube resonance. Because of the extremely short sound path of the tia high driver, a remarkable high-frequency extension and smoothness is achieved. The large bore also helps prevent clogging of the stem and obstruction of sound. 5

DIGITALLY RENDERED 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.

3D PRINTED Final shells are printed using our state-of-the-art 3D-printer using a hypoallergenic acrylic. The colors and materials we use have been speciﬁcally chosen for longevity and durability. This process also allows the digital renderings to maintain their detail for optimal comfort.

HAND ASSEMBLED Once shells are printed, our production team reﬁnes, smooths, and assembles the remaining components by hand. This process ensures each custom in-ear monitor is a unique piece of art, tailor-made for each customer.
