FIIO KA15 DAC and Headphone Amplifier

The versatile and fun little dongle Exploring new musical realms
Competition amongst audio dongles is becoming increasingly intense, and we know that only "innovation" can make us stand out.
Thus, the KA15 has been completely revamped inside and out. It combines FIIO' s experienced audio know-how on the inside with elements of retro tape recorder looks on the outside.
The new generation of FIIO' s 5-series audio dongles inspires endless fun with avant-garde innovation and appeals to quality enthusiasts with a practical design. It brings together great sound, ergonomics, fun, and aesthetics, all into a single tiny and convenient package!

Limitless enjoyment, Be your own music tuner
The audiophile-grade DSP allows the KA15 to feature a ten-band high-precision lossless PEQ, which operates smoothly and with high quality thanks to FIIO’s self-developed advanced adjustment algorithms. Through the control app or the web interface*, not only can you simulate or correct the frequency response curve of headphones but you can also export, import, share, and save EQ curves. Whether you choose to use officially recommended tunings or choose to share your tunings online with other enthusiasts, you can easily enjoy setting up EQ the way you want it.

Intelligently fun, Intelligent dynamic power consumption
Equipped with a high-performance, low-power processor and high-precision chips, the KA15 innovatively features real-time voltage and current monitoring for dynamic power adjustment. By recognizing the device’s playback status, it intelligently adjusts the overall power consumption, allowing your phone to run using less power. When you set a timer for music playback during the night, once the timer ends the KA15 will enter an ultra-low power sleep mode - so you don’t have to worry about your phone’s battery being low when you wake up the next day.

Surge of power, Patented Desktop Mode
Activate Desktop Mode for greater power, with balanced output power of 560mW+560mW, an astonishing increase of 207% compared to the KA5. This gives the KA15 the headroom to drive both low and high impedance headphones.

Flagship chips, All expertly tuned
The golden combination of a high-performance USB chip, dual CS43198 flagship DACs + dual high-performance SGM8262 op-amps, allow for high performance in a tiny area, giving the minute KA15 dongle more sound quality than its small size would suggest.

Capable decoder, All secrets unveiled
The KA15 supports up to 768kHz/32bit and DSD256 sampling rates, easily handling various lossless audio formats to meet your demands for great sound. Additionally, it is Hi-Res Audio certified, a testament to its excellent sound quality.

Intelligent app control, Continuous feature upgrades
FIIO' s capable software team made it possible for the KA15 to be fully controlled by the FIIO Control app*, including being able to adjust: PEQ, channel balance, UAC mode, volume, button mode, screen brightness, screen sleep time, theme, etc. More functionality is to be added through future firmware updates.

A joy to use, Ergonomically designed
To better suit your preferences, you can choose which control modes to use: Dual modes for volume control, 60-step quick adjustment or 120-step fine adjustment.

In-line controls, Music and calls at your fingertips
Microphones are supported*, as a part of the 3.5mm jack that supports the CTIA standard of in-line controls – allowing you to not only use your microphone, but also to control music playback and volume.
*iPhones and some Android phones may not support microphone input due to operating system limitations.
