The upgraded version of the Fosi Audio Q4 adds a microphone function, a K5 Pro headphone DAC-amplifier combo, and a next-generation audio converter featuring unmatched internal components, delivering even better performance and richer audio detail. Designed for gaming. The K5 Pro stereo DAC headphone amplifier is perfect for your home gaming system, comparable to 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 signals with low distortion and a wide dynamic range. Unique design: thanks to its 2-in-1 USB Type-C interface that serves as both a charging port and audio input, the K5 Pro is compatible with your phones. The RCA output can be connected to an amplifier or active speakers on your desk. The 3.5 mm AUX and microphone interface can drive headphones ranging from 16 to 300 ohms.
The K5 Pro headphone DAC uses the NE5532 op-amp chip from Texas Instruments. The circuit design of this DAC is optimized for a low noise floor and pure sound. Compared to the previous-generation Q4, the K5 Pro offers significant improvements in overall sound quality, making it even easier for you to lose yourself in your music.
