FiiO KA11 DAC and Headphone Amplifier

After nearly 2 years since the release of the KA1, we now introduce its upgraded successor — KA11. With a more compact body and enhanced power output, the KA11 delivers better sound quality. With exquisite design and materials, the KA11, despite its miniaturized form, boasts more powerful output, laying the foundation for outstanding audio quality with robust power output. Featuring an aluminum-magnesium alloy texture in dual colors, high-purity oxygen-free palladium-plated copper wires, supporting app control and UAC1.0 mode, and compatible with various systems... The KA11 has many other attractive designs and features.

With the KA11 being available with both USB Type-C or Lightning connectors, you can freely connect it to Android/iOS phones and tablets or to Windows and Mac computers – letting you freely listen to music at your convenience.

The KA11 supports control through the FiiO Control APP on Android devices with control over many aspects such as RGB lighting and digital filters.

UAC1.0 support

The KA11 supports two modes, UAC2.0 and UAC1.0. In the UAC1.0 mode, devices such as Switch and PS5 can be plug-and-play, allowing you to not only enjoy a low-latency gaming experience but also restore rich and detailed gaming sound effects, enabling you to quickly immerse yourself in the game.
