The KZ Castor is a groundbreaking dual-dynamic driver IEM designed to offer high-fidelity sound with unprecedented customization. Featuring a unique stacked dual-driver structure, it utilizes one 10mm driver dedicated to low frequencies and an 8mm driver for mid-to-high frequencies. This division of labor ensures powerful, undistorted bass while maintaining crystal-clear vocals and treble. With its integrated four-level tuning switches, the Castor allows for 16 different sound profiles, making it a versatile powerhouse for audiophiles, gamers, and bass enthusiasts alike.
Key Features:
-
Dual-Dynamic Driver Architecture: Unlike traditional IEMs, the Castor features two specialized dynamic drivers (10mm + 8mm) stacked to provide a richer, more layered soundstage with deep sub-bass and crisp high-end detail.
-
16-Level Tuning Customization: Equipped with professional-grade hardware switches, you can adjust the low and high frequencies independently. Whether you want a bass-heavy "Harman" profile or a flat "Audiophile" curve, the Castor adapts to you.
-
Harman Target Curve Optimization: The Castor is engineered to follow the acclaimed Harman FR curve, delivering a natural, balanced sound that is widely considered the "gold standard" for high-end audio performance.
-
Powerful Sub-Bass Performance: The dedicated 10mm low-frequency driver delivers punchy, textured bass that reaches down to the lowest sub-bass regions without bleeding into the mid-range.
-
Ergonomic "Comfort-Fit" Design: The high-quality resin cavity is shaped to fit the human ear canal naturally, providing superior comfort and exceptional passive noise isolation for long listening sessions.
-
High-Purity Silver-Plated Cable: Includes a premium, low-impedance silver-plated cable that ensures high-fidelity signal transmission and resists tangling.
-
Professional Acoustic Chamber: The internal cavity is precision-designed to eliminate unwanted resonance, ensuring the dual drivers perform with maximum accuracy.
