Traditional dongle DAC/amps often feel awkward to use—hanging from the phone, pulling on cables, and falling short on true portability. Some units add a screen, but it’s usually limited to basic information like volume, with little presence or purpose.
We wanted to break away from this pattern.
MD3 features a strong magnetic backplate that securely attaches to your phone, while its lightweight, compact design makes it effortless to carry wherever you go. We also adopted a circular display not just to show essential audio information, but to make interaction feel alive. Paired with the Vista Button, it lets you browse a photo album and upload images you love. MD3 represents our pursuit of balance in sound, design, and interaction. We hope MD3 becomes a companion you’ll want to take with you wherever you go.
What Does MD3 Sound Like?
Built as a HiFi–grade DAC/amp with no compromises in sound, MD3 offers a detailed yet musical listening experience.
Faithfully tuned to honor artistic intent and reveal the finest nuances, MD3 supports PCM 32bit/384kHz and native DSD256, with THD+N down to 0.00075% for detailed, lossless listening.
MD3 keeps music free from unwanted noise. Thanks to its aluminum alloy construction and well-engineered circuitry, the noise floor is reduced to 1.7μV, with a signal-to-noise ratio of up to 116dB.
Based on ensuring accurate reproduction, the MD3's sound tuning is more natural and enduring. It adds a slightly warm tone, making it more suitable for all-day listening.
Why We Chose the ESS Chipset?
In pursuit of ultimate resolution and listening excellence, our acoustic team conducted extensive comparisons and listening tests across mainstream chip solutions, including RT6863 and SGM8262. Rather than following the conventional path of maximizing raw power at the expense of sound quality, we chose the higher-cost yet sonically superior ESS flagship solution.
The ES9039Q2M flagship DAC chip delivers exceptional resolution, while its low power consumption makes MD3 an ideal audio companion for mobile devices.
A balanced amplifier circuit with four ES9603Q op-amps drives headphones with excellent separation, delivering a richly musical, fatigue-free sound.
MD3 comes with built-in funny animated images and emojis. You can also turn the outer display into your canvas with DIY wallpapers, from family photos to images of your favorite artists.
Built-in games like dice rolling, spin the bottle add a playful touch. Take a lighthearted break anytime, anywhere—right alongside your music.
Your Phone’s Little Backpack
Sixteen N52 high-strength magnets keep MD3 firmly attached to your iphone. Say goodbye to straps, bulk, and clunky distractions. An aluminum alloy isolation plate separates the PCB from the magnets, so you don’t have to worry about magnetic interference affecting sound quality.
Press to enter the photo album and you can flip through images with ease. After a long day of work, a simple press and its crisp, tactile response offer a small moment of stress relief.
The grid area beneath the display is designed as a canvas for your creativity—decorate it with stickers you love.
Thanks to its compact size and magnetic design, you can take MD3 everywhere. Why not let high-fidelity sound stay by your side?
Maybe this is what the future of DAC/Amp feels like.
