How to use

Connect the FiiO K11 to your audio source using the appropriate digital input supported by your source device, then connect headphones to the 6.3 mm output. Power the unit with the supplied DC adapter. Adjust volume and source selection on the device as required. For optimal results, allow the unit to warm up briefly after powering on and set source device output to match the K11's supported sample rate and bit depth when using high-resolution audio files.

Usage recommendations

Use quality interconnect cables and set your source device to the native sample rate when possible. Keep the K11 on a stable, vibration-free surface and avoid placing other electronic devices directly on top to minimize interference. If using headphones with lower sensitivity, increase the K11 volume gradually to find a clean listening level without clipping.
