Design That Honors Authentic Sound
Inspired by a passion for pure audio, EC Zero combines modern engineering with timeless craftsmanship. Featuring a CNC-machined aluminum body, tempered glass window, and retro UI, it balances vintage aesthetics with cutting-edge audio technology.

Precision CD Playback with Magnetic Disc Stabilizer
EC Zero adopts a tray-loading CD mechanism paired with an active magnetic disc stabilizer. This ensures rock-solid disc reading, safeguarding your collection while reducing vibrations for smooth and distortion-free playback in a quiet environment.

Professional CD Mechanism + Custom Servo System
Equipped with a professional-grade CD mechanism and custom servo system, EC Zero achieves fast response, precise signal capture, and millisecond-level dynamic compensation. Every note flows continuously and purely, delivering a faithful reproduction of your music.

Dedicated Custom Motor for Stable Performance
At the heart of EC Zero lies a custom motor with palladium-plated brushes, providing stable and reliable disc rotation. This ensures precise reading and builds the foundation for pure, accurate sound reproduction.

Premium DAC & Dual Op-Amps for Lifelike Sound
Powered by the AK4493S DAC and dual SGM8262-2 op-amps, EC Zero delivers warm, detailed, and natural audio. With a powerful output of 836mW @32Ω(balanced), it easily drives high-impedance headphones while maintaining clarity and musicality.

Long-Lasting Power & DC Support
A 5500mAh battery provides up to 10 hours of playback (3.5mm/4.4mm), and 18.5 hours in Bluetooth mode, freeing you from battery anxiety. For even greater performance, connect EC Zero to an external DC power source for stronger output and extended listening.
