Fosi Audio MD3 MagDac: A Bold Smartphone Companion
With the MD3 MagDac, Fosi Audio rolls out a standout external headphone amplifier for phones, aiming to blend portability with performance. This unit is crafted with a sturdy aluminum chassis that can cling to Qi2- or MagSafe-capable devices, including popular models like the iPhone 17, thanks to a magnetic ring on the back. The result is a compact partner that feels substantial in hand while staying light enough for on-the-go use.
Design and Display Styles
The front panel hosts a round display that can show animated creatures and three widgets in addition to the volume readout—think a cube, a wine bottle for spinning effects, and rock-paper-scissors. An orange button beneath the screen toggles between different modes, adding a touch of playful interactivity. On the right side, you’ll find controls to dial the volume, while a USB-C port and a 3.5 mm plus a balanced 4.4 mm headphone jack sit along the bottom edge for flexible connectivity.
Audio Power and Internal Tech
Inside, the MD3 delivers an output of 80 mW via the 3.5 mm jack and 180 mW through the balanced port, which should cover most in-ears and many entry-to-mid range over-ear headphones. The audio chain uses four ESS ES9603Q amplifier chips paired with an ESS Sabre ES9039Q2M DAC, capable of processing up to 32-bit/384 kHz files. The physical footprint measures 70 x 45 x 12 millimeters and it weighs about 50 grams, making it a compact yet capable unit for mobile listening.
Release, Pricing, and Availability
Launch is slated for May 25th, with pricing rumors hovering around $150. The manufacturer has not released an official price yet, but expectations point to a value-oriented offering given the feature set and the brand’s usual positioning.
