A versatile and fun new dongle Competition amongst audio dongles is becoming increasingly intense, and FIIO knows that only “innovation” can make them stand out. Thus, 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 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. Limitless enjoyment with ten-band high-precision lossless PEQ 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. *To access the web version of PEQ, please visit the FAQ section for the K15 on the FIIO official website for instructions on setup through the website. Intelligent dynamic power consumption 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. An outstanding display 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.
