Fosi Audio DS2 USB-C DAC & Headphone Amplifier — Dual Output, DSD256, 32bit/384kHz, 4.4mm Balanced

The Fosi Audio DS2 is a compact USB-C DAC and headphone amplifier designed for on‑the‑go listening and desktop setups alike. It blends portable convenience with high‑resolution decoding, helping you hear more detail in your music and movies without adding bulk to your gear.

High‑resolution sound with flexible connections

Decoded formats include DSD256 and PCM at 32‑bit/384‑kHz, offering crisp highs, defined mids, and solid bass response. Each channel can deliver up to 170 mW into 32 Ω, making it capable of driving a wide range of headphones through either a 3.5 mm single‑ended connection or a 4.4 mm balanced path.

Powered by two Cirrus Logic CS43131 DACs, the DS2 emphasizes a clean signal path with a remarkably low noise floor and minimal distortion. The result is a quiet background that helps micro‑details emerge while preserving the source’s nuances.

• High‑res formats: DSD256 and PCM 32/384 kHz decoding for faithful detail and dynamics.
• Ample drive: up to 170 mW per channel at 32 Ω for portable yet capable listening.
• Dual DAC architecture: low noise, wide dynamic range, and accurate sound reproduction.

Operational simplicity is a core design principle. Independent 60‑step volume controls offer smooth, stepless adjustment, and a built‑in volume memory recalls your last setting when you reconnect. The DS2 is built to integrate into everyday life without fuss.

Broad compatibility and solid build

Whether you’re pairing with iPhone 15 series, iPad Pro, or Android devices, DS2 also doubles as an external sound card for laptops, desktops, or Macs. The CNC machined metal chassis feels sturdy in your hand and fits comfortably in a backpack or laptop bag for travel.

• Wide device support: mobile phones, tablets, and computers.
• Rugged, premium construction: CNC metal shell for daily use and travel.

Note: The DS2 enables richer listening possibilities, but results depend on your source material, headphones, and listening environment. Think of it as a potential upgrade path rather than a guaranteed outcome.
