Product details

The DS3 from Fosi Audio is an innovative headphone amplifier designed as the first HiFi dongle with integrated gaming sound effects at the hardware level. It requires no additional software or drivers, making it particularly user-friendly. Featuring Fosi Audio's proprietary spatial audio algorithm, the DS3 supports native 7.1-channel audio inputs and transforms multichannel game audio into an immersive 2-channel 7.1 surround sound experience. This allows for a realistic soundstage, even with conventional stereo sources. In games with multichannel audio, activating the surround sound provides precise direction and distance perception, bringing the sound quality of engines and battlefields to life. With a maximum output power of 220 mW at 32 Ohms and a sampling rate of up to 32 Bit/768 kHz, the DS3 delivers outstanding audio quality for headphones with an impedance of 16 to 300 Ohms.

  • First HiFi dongle with gaming sound effects
  • Integrated spatial audio algorithm for 7.1 surround sound
  • Maximum output power of 220 mW at 32 Ohms
  • Supports PCM 32 Bit/768 kHz and DSD512.
