Greater control over your gaming and music audio:

The Fosi Audio K5 Pro is a compact DAC and headphone amplifier that provides a convenient desktop audio solution. It works as an external sound card and can be used with devices including PS5, Nintendo Switch, PC and Mac. Connect your headphones directly to the front panel, or route the audio through RCA to a separate amplifier or a pair of active speakers. This makes the K5 Pro suitable for gaming, music and everyday computer use when you want your audio connections and controls together in one compact device.

Digital audio and microphone connectivity in one device:

The K5 Pro builds on the Fosi Audio Q4 and adds a dedicated 3.5 mm microphone input. With the included headset splitter, you can connect a headset with a combined audio and microphone plug to the separate connections on the unit. The microphone function is supported when using the USB input, but not through optical or coaxial connections. On the rear, you will find USB-C, optical and coaxial digital inputs for connecting different audio sources. USB-C carries both the audio signal and the 5 V power supply. An RCA output also makes it easy to integrate the K5 Pro into an existing desktop or hi-fi setup.

Powerful headphone output and easy sound adjustment:

The built-in headphone amplifier supports headphones with an impedance of 16 to 300 Ohm. Output power reaches up to 1000 mW at 16 Ohm and 500 mW at 32 Ohm, providing flexibility for gaming headsets and many conventional hi-fi headphones. The audio circuitry uses Texas Instruments NE5532 operational amplifiers and is designed with a focus on low noise and distortion. A signal-to-noise ratio of at least 110 dB and total harmonic distortion below 0.003% help deliver clean audio reproduction. Separate knobs on the front let you adjust volume, bass and treble to suit your preferences. An input selector makes switching between digital inputs straightforward.
