Roseselsa x AAV CJ20 IEM Earphones

About the item

• Planar Magnetic Driver: CJ20 features a groundbreaking 14.2mm premium planar magnetic driver, delivering exceptionally fast transient response and minimal distortion for a sound that is both crystal clear and naturally smooth—never harsh or fatiguing. With its outstanding resolution, CJ20 captures every subtle detail in your music—the delicate intake of breath, the lingering resonance of a plucked string, the layered texture of drumbeat, revealing deeper emotion and richer nuance in every genre.
• All-Metal Body: The firm all-metal construction effectively resists daily bumps and wear, ensuring durability that stands the test of time. Its solid yet refined metal touch, coupled with a reassuring weight, conveys both reliability and sophistication. This design is not merely an aesthetic choice, the metal housing also effectively suppresses resonances, resulting in a darker background and purer audio details, which delivers an uncompromising listening experience.
• HIFI IEM Cable: CJ20 is equipped with a HIFI Graphene Plated OCC Single Crystal Copper cable, leveraging this revolutionary material to elevate your listening experience. Thanks to the wire's exceptional conductivity, audio signals are transmitted with nearly lossless speed and precision, preserving every nuance of the original recording. The sound flows more naturally with immediate dynamic responses and crisp transient attacks. You'll hear richer detail, clearer layers, and a more engaging sense of presence.
• Module Design: CJ20 features a quick-detachable modular plug system, including both 3.5mm and 4.4mm connectors, allowing you to easily adapt to different audio sources. This design not only expands compatibility but also enables you freely tailor your listening experience. With its secure connection and smooth switching mechanism, each plug change refreshes the way your headphones perform—giving you versatility without compromise.
• Co-Tuned with AAV: CJ20 is the first co-tuned IEM created in collab with Andy, host of the professional audio channel AAV. As an experienced audio content creator, Andy has poured years of critical listening expertise and a meticulous ear for detail into fine-tuning. It's built especially for rock enthusiasts with 2 sets of silicone eartips(wide bore & narrow bore). Like a professional audio guide, these earphones lead you closer to the original intention and emotion behind the rock genre.
