The Birth of “D”
COZOY’s first Dual-Magnet Dual-Cavity Dynamic Driver IEM introduces a new approach to dynamic driver design. By combining two independently developed dynamic driver units, the D1 delivers richer low-frequency extension, stronger midrange presence, and smooth, high-resolution treble. The result is a balanced, natural sound that is easy to enjoy across different music genres and use cases.
Independently Developed Dual-Magnetic Circuit Dual-Cavity Dynamic Driver
The D1 features a self-developed dual-magnetic circuit with a dual-cavity dynamic driver structure. Compared to conventional single-cavity designs, this structure improves anti-distortion performance and dynamic range. The powerful magnetic circuit enhances impact, clarity, and detail retrieval, creating a wider soundstage and a more immersive listening experience.
Graphene Diaphragm
The graphene diaphragm is carefully tuned through repeated material testing and acoustic matching. Its high stiffness and low mass enable fast transient response and precise sound reproduction. Driven by the dual-magnetic dual-cavity structure, it delivers powerful sub-bass extension, solid and natural midrange, and extended, well-controlled treble with low distortion.
Integrated Medical-Grade 3D Printed Shell & Nozzle
The earphone shell and nozzle are manufactured using high-precision medical-grade 3D printing. The ergonomic structure is designed and tested to fit the vast majority of ear shapes comfortably, ensuring long-term wearing comfort without fatigue. The smooth internal structure helps reduce unwanted resonance and improves overall acoustic stability.
Ergonomically Tuned Sound Structure
The internal acoustic cavity and sound channel structure are precisely tuned to achieve balanced frequency response and natural tonality. Imaging and positioning are clear and accurate, making the D1 suitable for critical music listening as well as immersive gaming, where spatial cues and detail matter.
Clear Imaging for Music and Gaming
With strong imaging accuracy and low distortion, the D1 allows you to clearly locate instruments and in-game sound cues. Reduced interference and cleaner signal reproduction help you react faster in games while maintaining a detailed and engaging music listening experience.
Single-Crystal Copper Silver-Plated Cable
The D1 comes with a high-quality single-crystal copper silver-plated cable with 0.78mm 2-pin connectors. The silver-plated structure improves transparency and layering, enhancing the texture of vocals and instruments. The durable PVC jacket ensures reliability for everyday use while maintaining flexibility and comfort.
