The versatile and fun little dongle Exploring new musical realms
Competition amongst audio dongles is becoming increasingly intense, and we know that only "innovation" can make us 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 Be your own music tuner
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.

Intelligently fun
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.
Compellingly fun
An outstanding display
The KA15 is the first to use a 0.96-inch IPS true color 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.
Surge of power 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.
Patent no.: ZL202321946664.8
Flagship chips All expertly tuned
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 All secrets unveiled
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 ound quality.
Intelligent app control Continuous feature upgrades
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 KA15 only supported on the Android version of the app.
A joy to use Ergonomically designed
To better suit your preferences, you can choose which control modes to use: Dual modes for volume control, 60-step quick adjustment or 120-step fine adjustment.
A/B button modes: mode A: short press volume +/-, long press previous/next track; mode B: short press previous/next track, long press to continuously adjust volume.
In-line controls Music and calls at your fingertips
Microphones are supported*, as a part of the 3.5mm jack that supports the CTIA standard of in-line controls – allowing you to not only use your microphone, but also to control music playback and volume.
*iPhones and some Android phones may not support microphone input due to operating system limitations.

FiiO KA15 — pocket-sized hi-res DAC/amp with retro flair
The FiiO KA15 compresses dual Cirrus Logic CS43198 DACs and a THX AAA-78 amplifier into a 50 g dongle, delivering high-resolution decoding and near-zero distortion for clean, detailed playback. Reviews from ecoustics and Audiophilepure highlight support for up to 32-bit/768kHz PCM, DSD playback, multiple gain settings, a 4.4mm balanced output and a 10-band parametric EQ via the companion app. Measured figures and listening notes praise a very low noise floor and lively dynamics, making the KA15 excellent with sensitive IEMs and most over-ear headphones. With distinctive styling, solid component choices and a sub-$110 price, it’s a feature-packed, portable option for listeners who want detailed, uncolored sound on the go.
Pros
- Dual Cirrus Logic CS43198 DACs paired with a THX AAA-78 amp produce clean, low-distortion, high-resolution conversion.
- Very low noise floor and high SNR deliver an effectively black background suitable for sensitive IEMs.
- Feature-rich connectivity and controls — USB-C input, 3.5mm and 4.4mm outputs, three gain settings and a 10-band parametric EQ via app — support wide use cases.
- Compact, well-built and visually distinctive design (50 g) makes it highly portable without sacrificing component quality.
&
Cons
- Companion app functionality is currently limited to Android, restricting full feature access for some users.
- Reviewers note there are less expensive alternatives in FiiO's lineup and elsewhere that may offer comparable or preferable sound for some listeners.
Sound Quality
89/100
The THX AAA-78 topology is called out for near-zero distortion and high output power, producing strong transient control and punch according to both reviews. Reviewers note the amp's ability to remain clean under load, delivering lively, well-controlled dynamics for a dongle.
Noise Floor
90/100
Audiophilepure reports an 'equally low noise floor (<1.7uV)' and a very high SNR (>123dB); ecoustics also emphasizes the low-distortion, clean output. Those explicit low-noise measurements and praise support a near-‘black-background’ performance suitable even for sensitive IEMs.
Headphone Compatibility
84/100
Provides 3.5mm single-ended and 4.4mm balanced outputs plus low/med/high gain settings and a THX AAA-78 power stage, so it will drive most efficient to mid-demand headphones well. Reviews don't provide specific output-impedance or wattage numbers and this is a compact dongle—excellent for IEMs and many full-size cans but unlikely to be a go-to for very power-hungry planars.
Build Quality
87/100
Reviewers praise the KA15's compact 50 g form factor and distinctive retro styling; Audiophilepure highlights strong internal component choices (SOC-like DAC implementation and quality op-amps). The product is characterized as well-built for a portable dongle with solid component selection.
Features Connectivity
92/100
Starts from the 80 baseline and adds USB-C input (+2), built-in high-res DAC (+3), 4.4mm balanced output (+2), multiple headphone outputs (+1), 3 gain settings (+2), and a 10-band parametric EQ via app (+2). The KA15 therefore offers a full-featured dongle DAC/amp package (high-res decoding, MQA/DSD support, balanced out, gain, and app EQ).
Value for Money
90/100
At US$109.99 reviewers call it a 'killer dongle' and note strong specs and performance for the price; ecoustics acknowledges cheaper alternatives exist but still positions the KA15 as competitively priced given its features. Overall reviewer sentiment frames this as a well-justified purchase within its segment.
