FIIO KA15 (Jade Audio KA15)

The KA15 has been completely reimagined, merging FIIO's audio expertise with a bold, retro-inspired aesthetic. Drawing on classic tape recorder design, this new-generation audio dongle is crafted for audiophiles and quality enthusiasts, bringing together superior sound, ergonomic ease, and modern appeal—all packed into a tiny, ultra-convenient form factor.

At its heart, the KA15 features an audiophile-grade DSP with a high-precision, ten-band lossless PEQ, supported by FIIO’s advanced, self-developed tuning algorithms. This system ensures smooth, high-quality operation, allowing users to customize and fine-tune their audio experience with ease.

With the dedicated control app or web interface, you can simulate or adjust the frequency response curve for various headphones. Save, export, import, or share EQ profiles, or explore officially recommended tunings. This flexible setup empowers you to personalize your sound experience and connect with other enthusiasts online.

Powered by a high-performance, low-power processor and precise internal chips, the KA15 also includes real-time voltage and current monitoring for optimized power use. By adapting to the device’s playback status, it intelligently minimizes overall power consumption, saving your phone’s battery life. Set a playback timer for nighttime, and the KA15 automatically enters ultra-low power sleep mode once playback ends, preserving battery life for the next day.

Uniquely, the KA15 is the first dongle of its kind to feature a 0.96-inch IPS true-color LCD screen, with support for both Chinese and English display. The intuitive settings menu, combined with a new retro-inspired dynamic UI, makes navigation easy and visually engaging. The simulated spinning tape adds a nostalgic touch, making the KA15 not just a tool but an experience.

The KA15 is packed with even more features: powerful 560mW+560mW desktop mode, dual CS43198 DACs with dual op-amps, support for 768kHz/32-bit and DSD256 playback, app control, 60-step quick adjustments, 120-step fine adjustments, microphone support, a 3.5mm jack with CTIA-standard in-line controls, and compatibility with devices like the Nintendo Switch and PS5 in UAC1.0 mode.
