Advanced Dual Dynamic Drivers

The Truthear x Crinacle ZERO IEM features dual dynamic drivers with dual polyurethane suspension composite liquid-crystal dome diaphragm and N52 Rubidium magnet double-cavity internal magnetic circuit dynamic driver. This setup ensures exceptional sound quality and precise audio performance.

High-End 3D Printing Technology

Utilizing DLP-3D printing cavity technology, typically reserved for high-end multi-driver products and custom earphones, the ZERO is meticulously crafted with a hand-made glue-dropping and capping process. This advanced technology enhances durability and sound accuracy.

Superior Cable Quality

Equipped with a copper-plated silver cable featuring a thicker diameter single strand, the ZERO delivers outstanding objective indicators and ensures superior audio transmission. This high-quality cable enhances the overall listening experience.

Efficient Driver Configuration

The ZERO houses a dual dynamic driver configuration with one driver measuring 10mm and the other 7.8mm. This combination provides a smooth, soft, and detailed sound, thanks to the mature internal magnetic circuit structure and flexible polyurethane suspension composite LCP liquid crystal dome diaphragm.

Optimized Frequency Division

The 7.8mm dynamic driver handles mid-high frequencies with an ultra-fine CCAW voice coil, improving sensitivity and providing clean, delicate treble tones. The 10mm driver, responsible for low frequencies, uses a special weighted voice coil to reduce natural resonant frequency for accurate frequency division, delivering a full and vigorous bass response.

Precise Hybrid Frequency Division

Leveraging high-precision DLP-3D printing technology, the ZERO features an acoustic nozzle structure with filtering functions and an accurately calculated RC frequency division. This design ensures that both dynamic drivers perform optimally, meeting objective sound quality indicators.

Exceptional Sound Quality

The ZERO IEM achieves a balanced low-frequency gain and high-frequency response aligned with HRTF characteristics, making it comparable to professional monitor earphones. It provides a natural and atmospheric sound, avoiding the cold and rigid tones typical of common monitor earphones.

Consistent Full-Frequency Phase

A critical factor in multi-driver earphones is phase consistency. The ZERO's full-frequency phase is highly consistent, avoiding the convergence issues common in multi-driver earphones. This eliminates unnatural listening experiences caused by phase distortion.

Innovative 3D Printing and Medical-Grade Materials

Manufactured by HeyGears using DLP 3D printing and medical-grade high-transparency resin, the ZERO's cavity is lightweight, skin-friendly, and reliable. The internal coloring process and delicate acoustic nozzle structure enhance both aesthetics and functionality.

Durable Glue-Dropping Molding

The ZERO adopts a sandwich structure for its cavity, comprising a front cavity, decorative panel, and glue-dropping capping. The glue-dropping process, solidified and shaped by ultraviolet light, ensures a beautiful design and reinforced firmness, further processed by hand-polishing and varnish spraying.

Versatile and Expandable Cable

The ZERO includes four strands of high-quality silver-plated cable and a universal 0.78 2Pin interface. This configuration allows for excellent sound quality and expands possibilities by enabling cable changes, offering flexibility and customization for audiophiles.
