Things to Know

Fosi Audio K5 Pro

  • Microphone input has no gain control; volume depends entirely on the OS/Console settings.
  • The internal DAC is limited to 24-bit/96kHz, which is lower than most audiophile competitors.
  • Tone controls can introduce distortion if cranked to maximum.

Fosi Audio SK02

  • No dedicated power switch; long-press the volume knob to turn on/off.
  • The volume status light flashes to indicate level changes, which some find annoying.
  • Form factor is tall and narrow; light weight means it can tip over if using heavy cables.
