Fosi Audio K5 Pro

The upgraded version of the Fosi Audio Q4 adds a microphone function, making the K5 Pro a headphone DAC amplifier combo—a next-generation audio converter with superior internal components, enhanced performance, and richer audio detail. Designed with gaming in mind, the K5 Pro stereo DAC headphone amplifier is perfect for your home gaming setup, functioning like an external sound card and compatible with PS5, computers, PCs, Macs, Nintendo Switch, active speakers, and more.

The K5 Pro USB DAC converts USB Type-C, optical, and coaxial signals into 3.5 mm AUX and RCA outputs with low distortion and a wide dynamic range. Its unique design features a 2-in-1 USB Type-C interface for both power and audio input, making it compatible with smartphones. The RCA output can connect to an amplifier or active speakers on your desk, while the 3.5 mm AUX and microphone interface can drive headphones with an impedance range of 16 to 300 ohms.

The K5 Pro headphone DAC uses the Texas Instruments NE5532 op-amp chip. Its circuit design is optimized for a low noise floor and clean sound. Compared to the previous-generation Q4, the K5 Pro offers significant improvements in overall sound quality, allowing you to immerse yourself even more deeply in your music.
