FiiO KA15 Portable USB-C DAC and Headphone Amplifier
Overview
The FiiO KA15 is a portable USB-C DAC and headphone amplifier with two Cirrus Logic CS43198 DACs, two SGM8262 op-amps and a 0.96-inch colour screen, in a small all-metal body inspired by retro tape recorders. It's for listeners who want one dongle that can run IEMs from a phone, drive full-size headphones in desktop mode, and tune the sound with a proper parametric EQ.
FiiO's patented desktop mode, switched on the body, raises the 4.4mm balanced output to 560mW per channel into 32 ohms, while the 3.5mm output delivers up to 180mW into 32 ohms. The KA15 plays up to 768kHz/32-bit PCM and DSD256 and is Hi-Res Audio certified, with SNR of 122dB single-ended and 123dB balanced. A DSP runs a 10-band lossless PEQ that you can set in the FiiO Control app or FiiO's web tool, including importing, exporting and sharing curves.
The KA15 monitors voltage and current in real time to adjust its power use to what's playing, and drops into a low-power sleep mode when a music timer ends. The IPS screen shows settings in a retro spinning-tape theme. You get 60-step or 120-step volume, two button layouts, CTIA in-line mic and remote support on the 3.5mm jack, coaxial digital output from the same jack, UAC1.0 mode for Switch and PS5, and a detachable cable that works with Android, iOS, iPadOS, Windows and macOS.
Simcoe Audio Video Insight
Leave desktop mode off for IEMs and turn it on for full-size headphones on the 4.4mm output, where it makes the biggest difference. The FiiO Control app only supports Android, but you can also set the PEQ from a computer through FiiO's web-based PEQ page. If you take calls on wired earbuds, the 3.5mm jack passes CTIA in-line mics and buttons, though FiiO notes iPhones and some Android phones may not support the mic.

Buyer's Guide
Who It's For
- The EQ Tuner: Wants a 10-band PEQ in a dongle.
- The IEM and Headphone Owner: Uses desktop mode for full-size cans.
- The Console Gamer: Uses UAC1.0 mode with Switch or PS5.
How It Compares
Compared with the FiiO KA13, the KA15 moves from dual CS43131 to dual CS43198 DACs, raises balanced desktop-mode power slightly from 550mW to 560mW, and adds a colour screen, a 10-band PEQ, 768kHz playback and in-line mic support.
