Fosi Audio K5 Pro Gaming DAC & Headphone Amplifier — USB-C/Optical/Coax to RCA & 3.5mm

Upgrade your gaming and listening experience with the Fosi Audio K5 Pro

The K5 Pro is the upgraded successor to the Q4, packing a microphone function and a refined internal design for richer, more detailed audio. Built for gaming and multimedia, it serves as an external DAC and headphone amplifier that can pair with PS5, PC, Mac, and active speakers.

Connectivity is flexible: it converts USB-C, Optical, and Coaxial signals into 3.5mm AUX or RCA outputs, delivering low distortion and a wide dynamic range. A thoughtful 2-in-1 USB-C port doubles as a charging/input design, making it easier to connect to compatible devices without clutter.

• USB Type C input supports up to 24-bit/96 kHz, with an additional 2-in-1 USB-C charging/input design.
• Optical and Coaxial inputs support up to 24-bit/192 kHz for clean digital-to-analog conversion.
• RCA and 3.5mm outputs let you connect to amplifiers, powered speakers, or your desktop audio setup.
• 3.5mm microphone interface enables in-game voice chats and clear voice capture when needed.

Sound quality and design

• Low-noise performance with THD ≤ 0.003% and SNR ≥ 110 dB, helping speech and music stay precise and detailed.
• Texas Instruments NE5532 op-amp contributes to a clean signal path and reduced audible hiss or hum.
• Compact, single-unit chassis combines master volume, bass, and treble controls with an input mode switch for quick tone shaping.

Controls, compatibility, and what you get

• Master volume, bass, and treble knobs give you on-the-fly tuning without software requirements.
• Compatibility across PS5, PC, Mac, and other devices with USB-C, Optical, or Coaxial sources.
• What’s in the box: K5 Pro DAC amp, 3.5mm headphone splitter, 2-in-1 USB-A/C to USB-C cable, optical cable, and user manual.

Real-life uses include immersive gaming with clearer audio cues, enhanced music listening with tonal control, and a practical bridge between consoles, computers, and external speakers. The K5 Pro presents a practical, flexible path to richer sound without overpromising fixed results.
