Light it up Let the high-res music commence
Not only do the RGB lights around the knobs give the K9 and the desk space around it some fun personality, they also conveniently indicate the current audio sampling rate and Bluetooth format.
Professional PEQ For what you love
Through the FiiO Control app, you can quickly switch between 7 music tuning styles preset on the K9. If the selected tuning style fits the music you are listening to, you can acquire a more vivid and pleasant experience. If the preset tuning style is not to your liking, the 3 self-define PEQ (Parametric Equalizer) designs will help to fine adjust to your favorite listening style.
To show off your skills One app is enough
You can connect the K9 to your phone via Bluetooth, and with the addition of the FiiO Control app you get access to even more functionality. Adjust various settings such as filters, status indicators, EQ, and channel balance to exactly your liking.
