Display, design, and everyday use

The KA15 debuts a 0.96-inch IPS color LCD among similar dongles, with bilingual (Chinese/English) menus and a retro dynamic UI that mimics a spinning tape. This blend of modern hardware and nostalgic visuals makes navigation intuitive and engaging, whether you’re adjusting volume, PEQ, or screen brightness.

Powerful audio circuitry in a tiny form

Inside, the KA15 pairs dual CS43198 DACs with high-performance op-amps, delivering a compact yet capable signal path. It supports up to 768kHz/32-bit PCM and DSD256, and is Hi-Res Audio certified. The result is clean detail retrieval, wide dynamics, and accurate tonality across formats.

Connectivity that keeps options open

Beyond standard USB DAC functionality, the KA15 includes a 3.5 mm jack that also serves as SPDIF coax output, enabling access to external decoders for more listening options. It’s designed for broad compatibility with Android, iOS, iPadOS, Windows, and macOS, with a driver-free mode for quick setup with devices like Switch or PS5.

Easy control and future-ready features

FIIO Control app support lets you tune PEQ, adjust channel balance, switch UAC mode, and customize button behavior, screen brightness, and sleep time. Firmware updates promise additional features and refinements, keeping KA15 aligned with evolving listening needs.
