Audiophile-Grade DAC: This USB-C dongle DAC/amp pairs ES9039Q2M with 32bit/768 kHz PCM & native DSD512, delivering ≥122 dB SNR & <0.0003 % THD while pushing 220 mW@32Ω balanced—high performance meets low power draw for phones, PCs, and Switch
XMOS POWERED Processor: As the world's first DAC/amp to integrate XMOS POWERED in a battery-free design, DS3 runs a dual-core 1.6 GHz engine that fully unleashes the ES9039Q2M DAC, ensuring rock-stable, lossless audio streaming from source to decoder
Hardware Spatial Audio: Fosi's built-in algorithm turns 7.1-channel game audio into 360° surround, while a dedicated FPS effect pinpoints footsteps, reloads, and gunfire for instant positional accuracy on PC, PS5, or Switch—no drivers needed
HiFi & Gaming Dual Modes: Supports UAC 1.0 and UAC 2.0, with volume memory available in both modes. Eight filter options and an 8-band hardware-level PEQ - adjustable via a web-based control panel - allow precise sound customization without degradation
Family Design & Colors: CNC-milled aerospace aluminum and a tempered-glass skylight pare the portable dongle dac down to 16 g while flaunting the internal circuit board, plus DS3 comes in galaxy and obsidian to match the IM4 headphones
