Designed for listeners who want more from their digital audio, the Fosi Audio DS3 is a compact USB DAC and headphone amplifier that combines high-resolution audio, powerful amplification and hardware-level 7.1 spatial audio in a portable design.

Supporting PCM up to 32-bit/768kHz and native DSD512, the DS3 delivers detailed, high-resolution sound while its built-in spatial audio processing creates a wider and more immersive listening experience for both music and gaming.

Hardware-Level 7.1 Spatial Audio

Step into a more immersive soundstage.

The DS3 features Fosi Audio's in-house spatial audio algorithm, supporting native 7.1-channel audio input and reconstructing multichannel sound into an expansive 2-channel presentation.

Even with standard stereo sources, the DS3 can create a more spacious and lifelike presentation.
