Product details

The Fosi Audio DS1 is a compact USB-C DAC headphone amplifier crafted for portable, high-fidelity listening. Its slim profile travels easily from home to commute, delivering clean, immersive sound when paired with smartphones, laptops, tablets, or dedicated music players.

At its core lies the ESS Technology ES9038Q2M DAC, supporting DSD512 and PCM up to 32-bit/768kHz. This powerful combination aims to reveal subtle textures and precise details in your favorite tracks, while providing solid drive for a wide range of headphones without crowding the source device.

DS1 also delivers ample power for high-impedance headphones (above ~200 Ω), helping you reach comfortable listening levels with minimal compression. With two headphone outputs—3.5mm unbalanced and 4.4mm balanced—you can choose the setup that suits your headphones and preferences, from broad compatibility to more nuanced, detailed playback.
