Description

The DT03 is equipped with dual ES9219C chips. It has great signal-to-noise ratio of 119dB and the distortion as low as 0.0006% on the 4.4mm balanced output. Through the meticulous tuning by the engineers, DT03 has an impeccable sound quality performance, as it highlights the details and layering of the music.

With the dedicated high-precision clock crystal oscillator module, DT03 bypasses the built-in clock on the USB interface, which lowers jitter significantly. This purer signal outputs, combine with the dual DAC chips, make for a cleaner sound reproduction.

Mode switch between low and high gain, dedicated volume controls on the unit

The design goal of DT03 is to provide compatibility with various transducers, by providing a low and high gain switch to adapt with different impedance and sensitivity of the listening device. A dedicated volume adjustment button is set on the body to easily control the volume, which is great for everyday use.

3.5 and 4.4 Dual Output Interfaces: High Power Driving Output, Remarkable Sound

DT03 offers single-ended 3.5mm and balanced 4.4mm headphone. The single-ended output power is 78mW (for a 32Ω load), and the balanced output power is 195mW (for a 32Ω load). With the high-power driving output, it improves on transient speed, dynamics, power output headroom and accuracy. The musical details are captivating, the sound performance is robust and powerful, resulting in a further enhancement of the sound quality.

Type-C Interface with Interchangeable Cable Design, Plug-and-Play and no need for special drivers

The DT03 body adopts a Type-C female connector, making it compatible with any USB-C cable on the market. This greatly enhances the compatibility with source gears. The unit comes stock with a high-quality cable, which ensures signal integrity. DT03 is compatible with most Android/iOS/Windows/MacOS devices on the market without the need of dedicated drivers.

CNC milled aluminum shell, RGB LED sampling rate indicator

Not only does DT03 boast outstanding sound quality, but it also features an exquisite industrial design. It employs an aluminum alloy CNC shell, which is smooth to the touch and has an understated appearance. The shell material is effective in blocking noise and interference. Inside DT03, there's an injection molded plastic bracket that stabilizes the internal structure and reduces the risk of damage during daily use. On the surface is an RGB LED sampling rate indicator, which displays different colors according to the type of audio source and bit rate.

Portable Versatility With A Huge Sound

DT03 is LETSHUOER’s third entry into the portable dongle DAC lineup.

The market nowadays has an increasing demand for on-the-go performant audio gears.

As such, LETSHUOER developed the DT03, a portable sound device that strikes a balance between appearance and sound quality. An uncompromising piece that seeks to become the next step in pushing the envelope into a small package.
