Competition among audio dongles is becoming increasingly intense, and FiiO knows that only "innovation" can set the company apart. The KA15 has been completely redesigned inside and out. Inside, it combines FiiO's experienced audio know-how with elements of retro cassette players in its design.
Everyday Use
The FiiO KA15 is very easy to use: connect it to your smartphone, tablet, or computer, plug in your headphones, and it will start playing sound immediately. A fun cassette animation is displayed on the screen during playback. The device is immediately recognized by all popular operating systems and works without delays.
Ten-band High-precision PEQ Equalizer
The high-precision lossless PEQ operates smoothly and with high quality thanks to advanced tuning algorithms developed by FiiO. With the control app or web interface, you can not only model or adjust the frequency response curve of your headphones but also export, import, publish, and save equalizer curves. Whether you decide to use officially recommended settings or share your settings online with other enthusiasts, you can easily customize and use the equalizer as you please.
Intelligent Dynamic Power Consumption
Equipped with a high-performance, low-power processor and precision microchips, the KA15 features an innovative real-time voltage and current monitoring function for dynamic power adjustment. Recognizing the playback status on the device, it intelligently adjusts the overall power consumption, allowing your phone to operate with lower energy costs. If you set a timer for music playback during the night, after this time, the KA15 will switch to a super-low power consumption sleep mode, so you won't have to worry about your phone's battery draining when you wake up the next day.
Outstanding Display
For the first time among similar devices, the KA15 features a color IPS LCD screen with a diagonal of 0.96 inches, which supports display in both Chinese and English. The settings menu has been designed to be more intuitive and user-friendly. Additionally, the KA15 features a new dynamic user interface in a retro style, combining technological innovation with classic design. With the simulated rotating tape, you can truly experience the uniqueness of the KA15.
Increased Power
Activate the desktop mode to increase power, with a balanced output power of 560 mW + 560 mW, a stunning 207% increase compared to the previous KA5 version. This gives the KA15 enough headroom to work with both low-impedance and high-impedance headphones.
Time-Tested Cirris Logic Chips
A superb combination of a high-performance USB chip, two flagship CS43198 DACs, and two high-performance operational amplifiers SGM8262 ensure high performance in a small form factor, providing the miniature dongle KA15 with higher sound quality than expected due to its small size.
Powerful Decoder
The KA15 supports sampling rates up to 768 kHz/32-bit and DSD256, making it easy to handle various lossless audio formats to meet your demands for excellent sound. Furthermore, it is certified as Hi-Res Audio, attesting to its superior sound quality.
Built-in Control Elements
Microphone support is provided by a 3.5mm jack that supports the CTIA standard for built-in control elements, allowing you to not only use a microphone but also control music playback and volume.
