Enjoy higher-quality sound
The FIIO KA11 is a specialized HiFi USB adapter that connects to phones, tablets, and computers. Inside are high-performance DAC and headphone amplifiers that work together to bring a higher-quality listening experience.
Even more compact but still powerful
Compared to the previous generation product, the KA11 is even more compact – making it even more portable and easier to carry around and use.
Thoughtful design and specially chosen parts allow the KA11 to have a large power output despite its compact size, making for a solid foundation behind its great sound.
Specially-designed HiFi circuit
A high-performance DAC and op-amp, a high-precision crystal oscillator, as well as an independent power supply are all combined in a specially-designed audio circuit that allows the KA11 to effortlessly produce great sound.
The high-quality parts are all carefully laid out on an immersion gold finish circuit board, allowing the KA11 to have great measurements. As a result, the KA11 is Hi-Res Audio certified – a testament to its excellent sound.
High-quality cable and eye-catching design
The cable is made of high-purity oxygen-free palladium-plated copper wires, which allow for low impedance, quick transmission of signals, and resist external interference. The copper wires are covered by a layer of flexible silicone and braided cloth, making for a soft yet durable cable.
The aluminium-magnesium alloy body is tough, yet also looks elegant with its perfectly placed curves and its inlaid designs. It is a device that will surely catch your eye.
Compatible with many devices
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.
App control support
The KA11 supports control through the FiiO Control APP on Android devices with control over many aspects such as RGB lighting and digital filters.
PCM 48kHz or below sampling rate, standby mode: light blue light
PCM above 48kHz sampling rate: yellow light
DSD: green light
UAC1.0 support - Giving you an immersive gaming experience!
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.
*Note: The UAC1.0 mode needs to be switched in the FiiO Control app.
