FiiO KA15 sky blue

The FiiO KA15 marks a distinctive milestone in the evolution of portable audio converters. By combining solid technical performance with visual innovation, this DAC/amplifier introduces the first color LCD screen in its class, while maintaining an accessible price point around €100. Its dual Cirrus Logic CS43198 architecture, paired with a THX AAA-78 amplifier, delivers 560mW of power per channel—enough to efficiently drive a wide range of headphones and earphones.

Revolutionary Design and User Interface

The KA15 breaks the aesthetic codes of portable DACs with its 0.96” IPS LCD screen, which displays an animated audio cassette during playback. This nostalgic approach, inspired by the iconic Sony Walkman, transforms a simple converter into a technical curiosity. The screen also shows real-time audio parameters, voltage, and amperage, offering an unprecedented visual control over performance.

The construction features a CNC-machined aluminum chassis, anodized and polished, providing premium robustness despite a light weight of just 21 grams. The three physical buttons adopt retro visual cues while allowing direct access to settings without the need for a mobile app. This standalone approach sets the KA15 apart from many competitors that rely on smartphones for configuration.

Audio Performance and Technical Architecture

The dual Cirrus Logic CS43198 DAC architecture, combined with SG Micro SGM8262 operational amplifiers, delivers impressive measured performance. On the 4.4mm balanced output, the device achieves a signal-to-noise ratio of 113dB with 0.0004% harmonic distortion, while the 3.5mm unbalanced output offers 122dB SNR and 0.00045% THD [according to provided specifications].

The sound signature is characterized by a slight warmth that avoids digital coldness, while preserving detail and treble extension. This subtle coloration makes listening more engaging during long sessions, especially with recordings that are too bright or aggressive. The soundstage offers good width with precise instrument placement.

Desktop mode delivers up to 560mW per channel at 32Ω, far exceeding the needs of most in-ear monitors while remaining sufficient for moderately demanding headphones. This power comes with an exceptionally quiet background, with no audible hiss even at high volume.

Versatility and Extensive Connectivity

The KA15 excels in versatility thanks to its selectable Class AB and H modes. H mode prioritizes energy efficiency for portable use, while AB mode maximizes performance for desktop use. This duality allows you to adapt the device’s behavior to your listening context.

USB-C connectivity ensures broad compatibility with Android smartphones, iPhones (adapter required), computers, and PlayStation 5 or Nintendo Switch gaming consoles. The 3.5mm output also supports USB-to-SPDIF bridge functionality, allowing connection to external DACs or hi-fi systems.

Intelligent power management automatically detects audio activity and adjusts consumption accordingly. In pause mode, consumption drops by 80% compared to the previous KA5, and by 93% in standby. This optimization preserves your smartphone’s battery life during extended listening sessions.

Software Ecosystem and Customization

The FiiO Control app offers full control via Android smartphone, complemented by a web interface accessible from any browser. This cross-platform approach ensures access to settings regardless of the source device.

The 10-band parametric equalizer allows for fine-tuning of the sound signature. Unlike basic EQs, this implementation lets you precisely control the center frequency, bandwidth, and gain, offering audiophile-grade correction flexibility. Settings are saved in the KA15’s internal memory, independent of the source device.

Selectable digital filters and volume modes (60 or 120 steps) can be tailored to your listening preferences. Right/left balance, screen brightness, and timeouts are also configurable as needed.

Premium Build and Finish

The CNC-machined aluminum chassis reflects a level of quality rarely seen in this price range. Anodizing and polishing provide a durable finish that resists scratches and daily wear. Midnight black and sky blue color options offer distinct aesthetic choices.

The inclusion of a lanyard eyelet shows attention to portable use, though the accessory is not included. This omission, along with the absence of a USB-C to Lightning cable for iPhone, are the only notable drawbacks regarding accessories.

While the LCD screen is attractive, it does introduce a potential point of fragility with repeated handling. However, its protection by the metal chassis helps limit the risk of accidental breakage.
