Fosi Audio MD3 Portable Headphones Amp
The Fosi Audio MD3 MagDac rethinks the portable DAC by magnetically attaching to the back of MagSafe and Qi2-compatible smartphones instead of dangling from the USB-C port. Compact enough to disappear into your pocket, it delivers a cleaner, more practical wired listening experience without the usual cable clutter.
Inside, the MD3 combines a flagship ESS ES9039Q2M DAC with four ES9603Q amplifier chips, supporting 32-bit/384kHz PCM, native DSD256, and headphones from 16 to 300 ohms. It delivers up to 180mW through its balanced 4.4mm output, alongside a standard 3.5mm jack, making it equally comfortable driving IEMs and full-size headphones.
The precision-machined aluminum body weighs just 50 grams and features a 1.28-inch circular LCD that displays playback information, volume, and interactive extras including customizable images. Physical controls, 100-step volume adjustment with memory, and dual USB-C ports allow simultaneous charging and playback, ensuring uninterrupted listening sessions.
With thoughtful engineering, premium components, and a magnetic design that finally makes portable wired audio feel seamless, the Fosi Audio MD3 MagDac is one of the smartest DAC and headphone amp combinations we've seen for modern smartphones.
