FiiO SNOWSKY Tiny A / Tiny B Portable USB DAC & Headphone Amplifier
The FiiO SNOWSKY Tiny A and Tiny B bring high-resolution audio decoding, customizable sound tuning, and practical headphone connectivity into an exceptionally compact USB DAC and headphone amplifier. Supporting PCM up to 32-bit/384kHz and DSD256, both models feature 10-band parametric EQ, a precision-crafted all-metal chassis, and convenient USB-C connectivity. The Tiny A combines a 3.5mm headphone output with USB-C charging passthrough, while the Tiny B offers simultaneous 3.5mm and 4.4mm headphone outputs. Designed for smartphones, tablets, computers, and compatible gaming consoles, the SNOWSKY Tiny series makes portable HiFi listening more flexible and accessible.
High-Resolution PCM 384kHz and DSD256 Decoding
Despite its miniature dimensions, the SNOWSKY Tiny series supports high-resolution digital audio playback up to 32-bit/384kHz PCM and DSD256. Its integrated USB DAC architecture converts digital audio signals into analog output for wired headphones and in-ear monitors. Whether listening to lossless music, high-resolution recordings, or everyday streaming content, the Tiny A and Tiny B provide a dedicated external audio solution for compatible USB-C devices. Both models carry Hi-Res Audio certification, reflecting their support for high-resolution audio playback.
Advanced 10-Band Parametric EQ for Personalized Sound
At the heart of the Tiny series is an integrated audio DSP system that enables precise 10-band parametric equalization. Through the FiiO Control app or compatible web interface, users can adjust individual frequency bands, gain levels, and Q values to customize the tonal balance of their headphones. This level of control allows listeners to refine bass impact, adjust vocal presence, or shape treble response according to their preferences. Custom sound profiles can also be saved and shared, making the Tiny series a flexible solution for enthusiasts who enjoy experimenting with personalized sound signatures.
Tiny A: 3.5mm Headphone Output with USB-C Charging Passthrough
The SNOWSKY Tiny A is designed for listeners who want to use wired earphones while keeping their connected device charged. It features a 3.5mm single-ended headphone output alongside an additional USB-C charging port, allowing compatible devices to receive power during audio playback. The charging passthrough supports a maximum rated current of 2A and voltage of 20V, subject to the connected charger and host device. This practical configuration is especially useful for extended listening sessions, mobile entertainment, and everyday use with compatible smartphones, tablets, and laptops.
Tiny B: Simultaneous 3.5mm and 4.4mm Headphone Outputs
The SNOWSKY Tiny B offers dual headphone connectivity with both 3.5mm and 4.4mm output jacks. Both connections can be used simultaneously, allowing two compatible sets of headphones or earphones to play audio from the same source. The 4.4mm socket provides convenient compatibility with earphones fitted with 4.4mm plugs. Importantly, the 4.4mm connection uses an internally single-ended amplification architecture rather than a true balanced amplifier circuit. This configuration emphasizes flexible physical connectivity without requiring separate output adapters.
Compact Direct-Plug USB-C Design
Both Tiny models feature a compact T-shaped construction with an integrated USB-C connector that plugs directly into compatible devices. This eliminates the need for a separate USB DAC connection cable and reduces the amount of equipment required for portable listening. Their side-mounted audio connectors help keep headphone cables positioned away from the main USB-C connection, making the overall setup more convenient for handheld use. The lightweight design also makes the Tiny series easy to carry alongside everyday audio accessories.
Precision CNC-Machined All-Metal Construction
The Tiny A and Tiny B feature finely crafted metal housings manufactured using precision CNC machining and polishing processes. Their compact chassis combines structural rigidity with a smooth, refined exterior finish. Weighing approximately 7g for the Tiny A and 10g for the Tiny B, both models are designed to remain lightweight without sacrificing the tactile quality of metal construction. Their minimalist form and carefully positioned connectors make them suitable for portable audio setups where space and convenience are important.
RG Sampling Rate Indicator
An integrated RGB indicator provides an immediate visual reference for the audio format being decoded. The indicator changes color according to the input signal: light blue for PCM up to 48kHz, yellow for PCM above 48kHz, and green for DSD playback. This practical feature allows listeners to identify the current decoding status without opening additional software. The indicator can also be disabled through the FiiO Control app on supported Android devices.
Convenient In-Line Controls and Microphone Support
The SNOWSKY Tiny series supports compatible headphone in-line controls, allowing users to manage music playback, volume adjustment, and calls without relying entirely on their connected device's screen. Microphone-related functions are also supported, making the series suitable for compatible headsets used for voice communication, gaming, and everyday calls. The availability of specific functions may vary depending on the connected headphones, host device, application, and operating system.
Wide Compatibility with Smartphones, Computers, and Gaming Consoles
With support for both USB Audio Class 2.0 and USB Audio Class 1.0 modes, the Tiny series can work with a broad range of compatible digital devices. Supported platforms include Android, iOS, HarmonyOS, Windows, macOS, and Linux, along with compatible gaming consoles such as the Nintendo Switch and PlayStation 5. The selectable USB audio modes help accommodate devices with different audio protocol requirements. For users who switch between portable music listening, desktop audio, and gaming, the Tiny series offers a versatile wired audio connection.
FiiO Control App and Web-Based Audio Customization
Beyond basic USB audio playback, the Tiny series integrates with the FiiO Control ecosystem for advanced device customization. Users can configure 10-band PEQ settings through the Android application or supported web interface, including frequency, gain, and Q-value adjustments. The software also provides access to supported device settings such as USB audio mode selection and audio control options. This approach allows users to adapt the listening experience to different earphones, music genres, and personal preferences without requiring additional external audio processing equipment.
