The FiiO K15 is a desktop DAC and headphone amplifier with full MQA support, onboard parametric EQ and Hi-Res Audio certification. Fed by a computer or streamer on a desk or shelf, it suits listeners who want hardware EQ for headphones they already like, set once and applied to every source.
Who the FiiO K15 is for
EQ tinkerers: Parametric EQ runs inside the K15, so corrections aren't rebuilt in software on every device you own.
Headphones that need a nudge: Adjust the sound of a pair you already like instead of buying another one.
Multi-source desks: Set filters once and they follow whatever source you connect, from a computer to a streamer.
MQA listeners: Full MQA support comes built in, alongside Hi-Res Audio certification.
Skip it if: you need something to carry around; the K15 is built to sit on a desk or shelf fed by a computer or streamer.

FiiO K15 vs similar options
vs FiiO K17: FiiO's flagship step-up: AK4191EQ + dual AK4499EX conversion, 4000mW + 4000mW balanced Class AB output and 31-band PEQ; it costs more, so pick the K15 if onboard PEQ is the main draw.
vs SMSL SH-X: An amp-only box (no DAC) with a low-noise design and JAS Hi-Res certification, for pairing with a DAC you already own; pick the K15 if you want DAC and headphone amp in one chassis.
