FiiO KA15 Overview

Enjoy lossless audiophile-grade sound anywhere in fun, retro-inspired style with the FiiO KA15, a portable DAC and headphone amp sporting dual CS43198 DACs, dual op-amps, and up to 32-bit 768 kHz and DSD256 sampling. With a distinct design that emulates the look of an old-school cassette player, aided by the color LCD, the KA15 is ergonomically friendly and unique.

Despite its resemblance to a cassette player, the KA15 provides Hi-Res certified audio and up to 560mW per side of headphone output power. The KA15 sports both an unbalanced 3.5mm and balanced 4.4mm headphone output and a USB-C input. The 3.5mm output also can be used as a coaxial S/PDIF output for digital audio systems. The multifunctional buttons, 10-band lossless parametric EQ, and many more functions can be controlled via the FiiO Control app for Android and iOS. When you need an extra surge of power to drive the most demanding headphones, Desktop mode delivers the goods. The KA15 includes a USB-C cable and a leatherette case.

Fun and Unique Design
To stand out in the increasingly competitive portable DAC market, the FiiO KA15 features a combination of precision audio know-how and a retro tape recorder design. This design appeals to quality enthusiasts and brings together great sound, ergonomics, and a fun aesthetic in one tiny package.
Be Your Own Music Tuner
Audiophile-grade DSP allows the KA15 to feature a 10-band lossless parametric EQ, which operates smoothly thanks to FiiO's advanced adjustment algorithms. Via the control app or web interface, you can simulate the correct frequency response curve of headphones and also export, import, share, and save EQ curves.
Intelligent Dynamic Power Consumption
Equipped with a high-performance, low-power processor and high-precision chips, the KA15 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, your KA15 will enter an ultralow power sleep mode once the timer goes off, so you don't have to worry about your phone battery being low when you wake up in the morning.
An Outstanding Display
The KA15 features a 0.96" IPS true-color LCD screen with support for both English and Chinese languages. The settings menus have been designed to be intuitive and user-friendly.

Additionally, the KA15 features a new retro dynamic UI, combining technological innovation with classic design. With the simulated spinning tape, you can truly feel the uniqueness of the KA15.

Surge of Power with Desktop Mode
Activate the patented Desktop mode for greater power, with a balanced output power of 560mW per side, an increase of 207% compared to the KA5. This gives the KA15 the headroom to drive both low- and high-impedance headphones.
Expertly Tuned Flagship Chips
The KA15 sports the golden combination of a high-performance USB chip, dual CS43198 DACs, and dual SGM8262 op-amps, allowing for high performance in a tiny footprint.
Highly Capable Decoder
This device supports up to 32-bit / 786 kHz audio and up to DSD256, easily handling various lossless audio formats to meet your demand for great sound. Additionally, it is Hi-Res Audio certified, a testament to its excellent sound quality.
Intelligent App Control
FiiO's software team has made it possible to fully control your KA15 via the FiiO Control app. App control features include adjustable PEQ, channel balance, UAC mode, volume, button mode, screen brightness, screen sleep time, theme, and more. More functionality will be added in the future through firmware updates.
In-Line Controls for Music and Calls
Microphones are supported as part of the 3.5mm jack, which sports CTIA standards for in-line controls, allowing you to not only use your mic but also control music playback and volume. Note: iPhones and some Android devices may not support microphone input due to operating system limitations.
Metal Construction
The all-metal body is meticulously crafted via precisions CNC milling, anodizing, and polishing. The result is a smooth and refined texture that fits comfortably in your hand. The all-metal construction also effectively reduces external interference for purer sound and improved audio quality.
