Customize Your Sound
KA15 is equipped with an audiophile-grade DSP that provides a 10-band high-precision PEQ equalizer. Thanks to FiiO’s advanced algorithms, the equalizer works smoothly and efficiently. Using the proprietary app or web interface*, you can not only simulate or adjust the frequency response of the headphones, but also export, import and share your settings. Want to use the officially recommended settings or prefer to create your own sound and share it with other enthusiasts? KA15 gives you this opportunity.

*Access to the web version of PEQ: top panel on fiio.com -> Support -> Web-based PEQ settings.

Intelligent Power Consumption
Equipped with a high-performance and energy-efficient processor, KA15 can monitor voltage and current in real time to dynamically adjust power consumption. Recognizing the playback status, the dongle independently optimizes power consumption, helping to save your smartphone’s battery. When using the play timer, for example, at night, KA15 will automatically enter the ultra-low power mode once the timer is up, so that your phone does not run out of battery in the morning.

Distinctive display
KA15 is the first dongle in its class to feature a 0.96-inch IPS screen that supports Chinese and English display. The intuitive menu makes it easy to set up the device. The new dynamic retro UI, including a spinning cassette tape animation, brings a special atmosphere and highlights the uniqueness of KA15.

Advanced Features
Besides these, the KA15 offers a host of other features: a powerful 560mW+560mW mode for desktop use, dual CS43198 DACs and dual op amps, 768kHz/32bit and DSD256 support, app control, 60- and 120-level volume adjustment, microphone support, and compatibility with Switch, PS5, and other devices in UAC1.0 mode.
