Key Features

  • The new generation of FIIO’s 5-series audio dongles inspires endless fun with avant-garde innovation and appeals to quality enthusiasts with a practical design. It brings together great sound, ergonomics, fun, and aesthetics, all into a single tiny and convenient package. The KA15 has been completely revamped inside and out. It combines FIIO’s experienced audio know-how on the inside with elements of retro tape recorder looks on the outside.
  • The audiophile-grade DSP allows the KA15 to feature a ten-band high-precision lossless PEQ, which operates smoothly and with high-quality thanks to FIIO’s self-developed advanced adjustment algorithms. Through the control app or the web interface*, not only can you simulate or correct the frequency response curve of headphones but you can also export, import, share, and save EQ curves. Whether you choose to use officially recommended tunings or choose to share your tunings online with other enthusiasts, you can easily enjoy setting up EQ the way you want it.
  • Equipped with a high-performance, low-power processor and high-precision chips, the KA15 innovatively features real-time voltage and current monitoring for dynamic power adjustment. By recognizing the device’s playback status, it intelligently adjusts the overall power consumption, allowing your phone to run using less power. When you set a timer for music playback during the night, once the timer ends the KA15 will enter an ultra-low power sleep mode - so you don’t have to worry about your phone’s battery being low when you wake up the next day.
  • The KA15 is the first to use a 0.96-inch IPS true colour LCD screen among similar dongles and supports both Chinese and English language display. The settings menus have been designed to be more intuitive and user-friendly. Additionally, the KA15 features a new retro dynamic UI, combining technological innovation with classic design. With the simulating spinning tape, you can truly feel the uniqueness of the KA15.
  • Patented Desktop Mode - Activate Desktop Mode for greater power, with balanced output power of 560mW+560mW, an astonishing increase of 207% compared to the KA5. This gives the KA15 the headroom to drive both low and high-impedance headphones.
  • Dual CS43198 - The golden combination of a high-performance USB chip, dual CS43198 flagship DACs + dual high-performance SGM8262 op-amps, allow for high performance in a tiny area, giving the minute KA15 dongle more sound quality than its small size would suggest
  • Capable decoder - The KA15 supports up to 768kHz/32bit and DSD256 sampling rates, easily handling various lossless audio formats to meet your demands for great sound. Additionally, it is Hi-Res Audio certified, a testament to its excellent sound quality.
  • Intelligent app control - FIIO’s capable software team made it possible for the KA15 to be fully controlled by the FIIO Control app*, including being able to adjust: PEQ, channel balance, UAC mode, volume, button mode, screen brightness, screen sleep time, theme, etc. More functionality is to be added through future firmware updates. *FIIO Control app control over the KA15 is only supported on the Android version of the app.

Got the KA15 for Christmas and it is a ***powerhouse*** of a DAC/amp. It doesn't have even a semblance of an issue powering my greedy over ear planars. Wanted to upgrade from the KA11 as while it was definitely powerful, the permanently attached cable created some issues when it would start to cut out after a couple of months of regular/constant use. The KA15 instantly solved that issue, gave **even more** power, and now also has a cool cassette aesthetic. I will be using and monitoring any issues I see. Currently there seems to be an occasional issue if I have the DAC in my pocket with my phone playing music (slight static) but I'm pretty certain it's a cable issue rather than the DACs. Regardless I will be keeping track of it to see if that's the actual cause, otherwise, I'm definitely satisfied with this cute little DAC/amp combo.
