• Small dongle with wide connectivity
• Flagship dual DACs for excellent sound

High-Quality Sound with Dual DACs

The KA5 features dual Cirrus Logic CS43198 DACs, known for their efficiency and their ability to sound good with a wide variety of music, to give you a serious upgrade to your sound. Two DAC chips ES9068AS handle the left and right channels respectively, and the fine "core" polishes the quality and sound quality. Listen to your favorite song list and revel in the beautiful song in an instant.

High-Resolution Decoding for Audiophile Listening

The KA5 supports up to 32bit/768kHz PCM and DSD256 decoding, allowing you to really dig into and listen to the heart of your music, no matter what device you may have it connected to. For better audio performance, the KA5 utilizes a 6-layer immersion-gold PCB as well as high-performance ultra-low noise op amps for powerful, robust sound.

Serious Components for Serious Power

The aggressive lines of the KA5 give it a bold look, while the carefully designed texture makes it a joy to handle. The dual outputs on the right side of the KA5 hint at its powerful capabilities. *3.5mm output supports SPDIF output. After enabling the SPDIF output in the settings menu, the USB audio signals can be converted to SPDIF signals. Connect the KA5 to a higher-end external decoder to set up a better audio system.

Bold Ruggedness with Highly Capable Features

The KA5 is built to last with its bold rugged design. It features a flexible local operating system with an OLED display and physical buttons, making navigating the settings menu and looking at the playback display more straightforward and intuitive. In addition, the KA5’s built-in MCU processor handles complex operations with ease, further making the KA5 a joy to use. *Volume buttons A/B mode

Convenient Control with Companion App

Besides the local KA5 operating system, you can use the FiiO Control App to take control over the KA5. Use either method to conveniently dial in the KA5 exactly how you want it. *The KA5 can only be controlled through the FiiO Control app on an Android device.

Small Size, Large Functionality

Despite the KA5’s compact size, it packs a ton of functionality – such as high and low gain, 5 selectable filters, L/R channel balance, and screen flip. Let the KA5 redefine what a tiny audio dongle can do for you.

Immersive Gaming Experience with UAC 1.0 Support

The KA5 supports UAC2.0 and UAC1.0 modes. With the UAC 1.0 mode, you can connect the KA5 to the Switch and other various devices, allowing you to experience rich and detailed sound effects that make your gaming sessions much
