Product details

The Fosi Audio DS1 is a compact USB DAC headphone amplifier featuring an optimized HiFi audio architecture that delivers high-resolution sound quality. This portable USB DAC is compatible with systems such as Android, iOS, Windows, and Mac, as well as various devices like smartphones, computers, tablets, laptops, and audio players. It is wonderfully versatile for commuting, at home, in the office, or while gaming. The DS1 utilizes ES9038Q2M DAC chips that support DSD 512 and 32 Bit/768 kHz PCM. It boasts top-notch specifications and high-performance outputs capable of driving even the most demanding headphones with an impedance over 200 Ohms. The DS1 provides ample power with a high signal-to-noise ratio, low distortion, and nearly zero noise. The traditional 3.5mm headphone output is widely compatible with most headphones, while a 4.4mm balanced headphone output offers a more detailed audio experience.
