High-Purity Oxygen-Free Copper Flat Cable: The Key to Superb Sound
The OFC (Oxygen-Free Copper) wire core offers excellent conductivity, providing a stable and high-quality sound output foundation for the earphones. This ensures that every note is transmitted accurately and without loss. The TPE transparent outer sheath is resistant to bending and pulling, significantly extending the cable's lifespan.

Multi-Function In-Line Control for Easy Operation
The multi-functional in-line control simplifies operation with one-touch functionality for play/pause, skip track, and more. It also features a built-in microphone for clear audio pickup, enabling crisp and clear near-field voice commands and phone calls as if talking face-to-face.

Harman Target Version
The Harman target curve is a scientifically derived frequency response designed to make headphones and in-room audio systems sound like high-quality speakers in an acoustically treated room. Developed through extensive listener preference research by Sean Olive and the team at Harman International, it aims to deliver a natural and pleasing tonal balance

Based on the KZ Castor, the KZ Castor Pro version further refines the frequency response curve to better align with the Harman targeted curve. This upgrade delivers a significant improvement in performance parameters and sets a new benchmark for sound quality.
