The FiiO K11 is a desktop DAC and headphone amp that pairs a Cirrus Logic CS43198 DAC with 1,400mW per channel at 32Ω from its 4.4mm balanced output. It suits first desktop rigs, bedside setups and PS5 or Switch players who want driver-free USB-C plus optical and coaxial inputs in one 407g box.
Who the FiiO K11 is for
First desktop or bedside rig: One box handles DAC and amp duties, and three gain levels cover everything from sensitive IEMs to demanding headphones.
Planar headphone owners: On the 4.4mm balanced output and high gain, 1,400mW per channel at 32Ω is enough for most planars.
PS5, Switch and Mac users: It runs driver-free over USB-C on Windows 10+, macOS, PS5 and Switch; plug in and select it as the audio output.
TV and powered-speaker setups: Optical and coaxial inputs take a TV or console, and the RCA line out feeds powered speakers.
Skip it if: you want to stream from a phone over Bluetooth; the K11's inputs are USB-C, optical and coaxial.
Outputs: 4.4mm balanced, 6.35mm, RCA line out, coaxial out
SNR: ≥123dB
Driver-free USB: Windows 10+, macOS, PS5, Switch
Power: DC 12V/2A adapter (included)
Size and weight: 147 × 133 × 32.3mm, 407g
FAQ
Is this the regular K11 or the K11 R2R?
This is the regular FiiO K11 with the Cirrus Logic CS43198 DAC and 1,400mW balanced output. The K11 R2R is a separate, pricier model with a resistor-ladder DAC and 1,300mW output. For most desks the regular K11 is the better value.
Can it drive planar headphones like the HE400se?
Yes. 1,400mW per channel at 32 ohms from the 4.4mm balanced output is more than enough for the HIFIMAN HE400se and most planars. Use the balanced output and high gain for demanding headphones; sensitive IEMs are better served on low gain from the 6.35mm jack.
Does it work with PS5, Switch and Mac without drivers?
Yes. The K11 is driver-free over USB-C on Windows 10+, macOS, PS5 and Switch — plug in and select it as the audio output. Optical and coaxial inputs also let it serve a TV or console setup, and the RCA line out feeds powered speakers.

FiiO K11 vs similar options
vs FiiO K11 R2R: FiiO's resistor-ladder (R2R) version with NOS/OS modes, rated 1,300mW balanced against this K11's 1,400mW, and pricier; pick it for ladder-DAC conversion, the K11 for the CS43198 and a little more power.
vs Fosi Audio ZH3: Fosi's AK4493SEQ unit pushes 2,570mW into 32 ohms balanced versus the K11's 1,400mW and adds XLR preamp outputs and a remote; it costs more, so pick it for XLR or extra headroom.
vs SMSL DS200: Adds Bluetooth 5.1 so a phone can stream to it, and runs a CS43131 DAC with 3.5mm and 4.4mm headphone outputs; pick the K11 if your headphones use a 6.35mm plug.
In: USB-C, optical, coax; Out: 4.4 mm, 6.35 mm, RCA line, coax
