PREMIUM ESS DAC & QUAD AMPLIFIER TECHNOLOGY

At the core of the MD3 is the flagship ESS ES9039Q2M DAC chip, paired with quad ES9603Q amplifier chips in a true balanced architecture. This advanced setup ensures exceptional clarity, ultra-low distortion, and a clean as well as noise-free background for highly detailed sound reproduction. With output power reaching up to 180mW via the 4.4mm balanced port and ~75–80mW via 3.5mm, the MD3 easily drives IEMs and entry-level headphones with ease. You get a dynamic, controlled and immersive listening experience across all genres.

MAGNETIC SNAP-ON FORM FACTOR FOR SMARTPHONES

The MD3 features a MagSafe-style magnetic design that securely attaches to compatible smartphones, creating a clean and compact audio setup. Sixteen N52 magnets in the back maintain a strong hold with user’s smartphone. The Hand-stitched leather and aluminium alloy isolation plate separates the PCB from the magnets, so you don’t have to worry about magnetic interference affecting sound quality. This eliminates messy cable management and keeps your setup streamlined for daily use. Its lightweight and pocket-friendly form factor makes it ideal for on-the-go listening, while still delivering premium performance without compromise.

PREMIUM CNC ALUMINUM BUILD QUALITY

Built with a CNC-machined aluminium chassis, the MD3 offers a solid and premium in-hand feel. The durable construction enhances longevity while maintaining a sleek, modern aesthetic. The precision-engineered body not only looks premium but also provides better heat dissipation and structural strength for long-term reliability. Apart from looking sleek and futuristic, it also maintains a lightweight build. Fosi Audio has kept the MD3 so much light in weight that any person can carry this ultra-portable device along all-day without feeling fatigued. The overall thickness is just about 0.47 inch, so it doesn’t even protrude very much.

HIGH-RESOLUTION AUDIO PLAYBACK SUPPORT

The MD3 supports 32-bit/384kHz PCM and native DSD256, allowing you to experience music in true high-resolution quality. Every detail, from micro nuances to powerful bass, is reproduced with precision and depth. This ensures a rich and lifelike audio experience, as described by Fosi Audio itself, that brings your favourite tracks closer to studio-level clarity.

DUAL USB-C PORTS WITH SIMULTANEOUS CHARGING SUPPORT

Equipped with dual USB-C ports, the MD3 allows simultaneous audio playback and device charging. This means you can enjoy uninterrupted listening sessions without worrying about battery drain. One port is placed on the top and the other is on the bottom. So, it becomes a practical solution for long commutes, work sessions or extended listening sessions while relaxing at home, ensuring convenience without sacrificing performance.

SMART LCD DISPLAY WITH CUSTOM FEATURES

The MD3 features a 1.28-inch rotatable LCD display that provides real-time playback information and easy access to controls. The intuitive interface enhances usability while adding a modern touch to the device. It also includes a built-in photo album and custom animations, allowing users to personalize the display for a more engaging and unique experience. It is also possible to turn the outer display into your own canvas with DIY wallpapers. Now, you can put everything on display, from family photos to images of your favourite artists.

PRECISE 100-STEP VOLUME CONTROL & INTELLIGENT VOLUME MEMORY

The MD3 offers a 100-step volume control system for highly precise sound adjustment. This allows you to fine-tune listening levels exactly to your preference, especially useful for sensitive IEMs. Each step is smooth and consistent, ensuring accurate volume control without sudden jumps or imbalance. With built-in volume memory, the MD3 automatically restores your last used volume level when reconnecting. This provides a seamless and convenient user experience every time you use the device. It also enhances safety by preventing unexpected volume spikes, making your listening sessions more controlled and reliable.

Beyond audio, the MD3 introduces fun image-based mini games that add an interactive element to your device. These playful features make the MD3 more than just an audio tool and make it an engaging companion which will cure your boredom while you are traveling.
The three β€œRolling Dice”, β€œWine Bottle” and β€œRock-Paper-Scissor” minigames bring a refreshing twist to portable audio gear, combining entertainment with functionality for a truly unique user experience.
