Dual ESS SABRE ES9219C DAC Chips & High-Precision Quartz Crystal Oscillator Module
The DT03 uses a dedicated high-precision quartz crystal oscillator module, bypassing the USB interface's built-in clock, delivering cleaner signal output. The combination of dual DAC chips achieves higher resolution sound. Equipped with dual ES9219C chips, the signal-to-noise ratio reaches 119dB, and the 4.4mm balanced output distortion is as low as 0.0006%.
High Power Drive Output
Enhances sound transmission speed, dynamic performance, power output, and accuracy. The DT03 offers both 3.5mm single-ended and 4.4mm balanced headphone outputs. The single-ended output power is 78mW (for 32Ω load), while the balanced output power is 195mW (for 32Ω load). The music details are captivating, and the sound performance is strong and powerful, significantly enhancing audio quality.
High/Low Gain Adjustment & Independent Volume Buttons
Designed with user scenarios and needs in mind, the DT03 offers low gain and high gain dual-mode switching to accommodate different impedance and sensitivity headphones, presenting different sound quality effects. The device has independent volume buttons for easy volume control and convenient daily use.
Type-C Interface with Replaceable Cable Design
The DT03 features a Type-C connector, compatible with most Android/iOS/Windows/MacOS devices on the market, requiring no special drivers.
CNC Aluminum Alloy Precision Machined Housing & RGB LED Indicator Light
The DT03 not only offers excellent sound quality but also has an exquisite exterior design. The aluminum alloy CNC housing provides a smooth touch and effectively blocks noise and interference. The internal structure is stabilized by an injection-molded plastic frame, reducing the risk of damage during daily use. The housing features RGB LED indicator lights that display different colors based on the audio source type and bitrate:
- PCM ≤ 96kHz: Green
- PCM = 176.4kHz 192kHz: Blue
- PCM ≥ 352.8kHz: Red
- DSD Hardware Decoding: Yellow
High-Quality Accessories
The DT03 package includes two high-quality signal transmission cables (12.5cm and 80cm Type-C to Type-C) and a Type-C to USB adapter, covering most usage scenarios and ensuring high-quality music enjoyment at any time. A deep black leather case is also included, providing a tactile leather texture to protect the device while enhancing its overall quality. (Note: The leather case is a standard accessory included in the package.)
