FiiO KA11 USB-C Portable DAC & Headphone Amplifier – Sunrise Silver
The FiiO KA11 is an ultra-compact USB Type-C DAC and headphone amplifier that instantly upgrades the sound of your smartphone, tablet, or computer. Built around a high-performance Cirrus Logic CS43131 DAC and a low-noise SGM8262 op-amp, it delivers clean, detailed, high-resolution audio with an impressively black background.
Don't let its tiny size fool you: the KA11 pushes up to 245mW per channel into 16Ω, enough to drive power-hungry IEMs and many full-size headphones. Weighing only about 8.5g, it is small enough to live in your pocket or stay attached to your phone all day.

Small Size, Serious Power
Thoughtful circuit design and carefully selected components allow the KA11 to provide a remarkably strong headphone output for its size — more than enough for most IEMs and many headphones.
Cleaner Sound, Clearer Details
A dedicated power supply stage and a high-precision crystal oscillator maintain stable timing and low noise, so quiet passages stay silent and subtle textures come forward naturally.
