It provides a whopping 153mW of clean output power with a clean, noise-free background. FiiO KA2 ensures you get a powerful performance with a pitch dark background in the output signal. It can drive most IEMs and some low-power requiring headphones with ease.


    Five Different Digital Filters:-

    Adjust the output to your liking with five pre-built digital filters on the KA2. You have to use the FiiO Control application on your smartphone to change the digital filters.


    Full Integration With FiiO Control Application:-
