EarAcoustic Zkaaai CIPHER

Unfinished Love
Lyrine Studio's first Cipher earphones, a limited edition collaboration with zkaaai, are equipped with a powerful nano-crystal ceramic diaphragm dome plus a flexible polymer polyurethane suspension, and dual-magnetic Tesla dynamic coils, which achieve "airy" sweet tuning with quantum-level precision. They also introduce an innovative "sonic nebula sound field" design, and the sound wave reflection path is optimized through fluid dynamics software simulation, allowing sweetness and transients to coexist for the first time. Eight groundbreaking color schemes + dual-version signal input architecture, and starry crystal diamond surface craftsmanship make Cipher not only an all-round HiFi benchmark for all scenarios, but also make high-fidelity sound quality a wearable dimensional belief.

Product Features
The Transition of Sweet Philosophy from Metaphysics to Measurable Science
The nanocrystalline ceramic diaphragm dome and flexible polymer polyurethane suspension are the physical material cornerstones of Cipher's sweet acoustics. The diamond-grade hyperbolic dome vapor-deposited zirconium oxide ceramic has a surface hardness exceeding sapphire and is over 40% lighter than traditional diaphragms. The superb material rigidity eliminates over 99% of segmentation distortion. At the same time, a precise annealing process homogenizes the stress within the diaphragm, ensuring third-harmonic distortion of <0.05%. Dozens of micro-airflow channels are laser-etched on the edge of the diaphragm to enhance the ductility of overtones above 16kHz, laying the foundation for Cipher's "sweet but not greasy" and mellow sound.

Super engine in one step, dual magnetic circuit and dual cavity, full performance
Cipher's dual-magnetic circuit, dual-cavity super-energy magnetic flux engine delivers powerful performance. Its ultra-1.0T Tesla dual-ring magnetic architecture features an inner ring focused on mid- and high-frequency precision, increasing magnetic flux density by 200%. The outer ring drives low-frequency transients, ensuring the diaphragm displacement speed is faster than 0.005ms, resulting in a sweet and smooth transient response. When playing the Rubinstein-Chopin Nocturne, the piano keys sound like melted black chocolate wrapped in gold foil, allowing sweetness and transients to coexist for the first time.

Nebula Sound Field: Thousand-dollar Sound Effects and Chaotic Reconstruction of Three-Dimensional Sound Waves
Cipher's acoustic particle duct metal outlet cavity is engraved with 12 sets of spiral grooves. The sound wave reflection path is optimized through fluid dynamics software simulation, achieving a 16kHz overtone extension like the Milky Way, an attenuation slope of -5dB/oct, and combined with a composite biological cotton filter, the vocal image is as sweet as candied cherry blossoms. At 2.5kHz, the phase offset is close to zero. Combined with the cavity's dual air pressure balanced punch hole design, the drum beats dive as deep as the abyss but the transients are sharp.

Jewelry-grade crystal diamond surface craftsmanship is a duet of acoustics and aesthetics
7075-grade aircraft aluminum is precision-milled on a five-axis machine tool, achieving a surface tolerance of ≤1.8μm. The ultra-rigid cover achieves over 99.5% resonance suppression, while maintaining a sound wave reflection distortion rate of ≤0.05%, delivering pure, high-fidelity sound. The surface's star-shaped crystal diamond finish gives Cipher a futuristic, high-precision finish and an aesthetically pleasing interpretation of jewelry-grade light patterns.

Sweet and mellow tuning frequency response
Tuning concept: Cipher's sweet peak accurately avoids the harsh area of the human ear (6-8kHz), and the airy slope of -4dB/oct can extend the overtone dissipation time by more than 300%.
 

• In the low-frequency (20-80Hz) area, at the 40Hz position, the -3dB deep-sea descends slowly, and every beat of "Dust Drum" sounds like a velvet-wrapped meteorite falling.
• The sweet core (200-3KH2) area rises gently at the 1KHz position ± 0.5 dB, and Mika Nakashima's sobbing voice in "Snow Flower" is like warm honey sliding through her throat.
• The sweet peak (4K-6kHz) area has an artistic lift of +1.8dB at 45Hz. Listening to the high position of the violin piece "Huogang" is like champagne bubbles bursting on the tip of the tongue.
• In the airy (8k-30kH2) area, at 10kHz position, the starlight rises slightly at +4.5dB, and the harp overtones sound like moonlight penetrating the mist, lasting for more than 0.8 seconds.

Thanks to its excellent frequency response, Cipher has a unique airy experience. At the same time, the sweet tuning style ensures that Cipher can present a balanced, relaxed, warm, listenable and omnivorous all-round music style. The super-performance unit quality also makes Cipher a true all-scenario benchmark earplug.

Comfortable and snug fit, it won't make you tired even if you wear it for a long time. It's also a perfect accessory for your ears.
Each one weighs only 4.1 grams, so light that it seems like nothing. The shell is made of ABS resin material with a touch-friendly paint. The surface ARTWORK design uses 7075 aviation-grade aluminum alloy with diamond cutting technology, which makes it shine brightly.
