The FiiO SNOWSKY Retro Nano is a compact Bluetooth DAC and headphone amplifier that blends playful cassette-inspired design with serious portable audio performance. At its core sit dual Cirrus Logic CS43131 DAC chips working in a fully differential configuration, paired with the Qualcomm QCC5125 Bluetooth SoC for stable wireless connectivity and low-distortion digital-to-analog conversion.

Supporting Bluetooth 5.1 with high-resolution codecs including LDAC, aptX Adaptive, aptX HD, aptX LL, aptX, AAC, and SBC, the Retro Nano delivers clean, detailed sound whether you are streaming from your smartphone or using it as a USB DAC. The 0.96-inch color TFT display (80 × 160) features a retro tape-style UI, showing codec, battery level, volume, sampling rate, EQ and more at a glance, making the device both fun and highly functional.

Designed for maximum flexibility, the Retro Nano offers both 3.5mm single-ended and 4.4mm balanced headphone outputs. Output power reaches up to 220 mW + 220 mW at 32 Ω from the balanced jack, easily driving a wide range of IEMs and portable headphones, while the ultra-low output impedance (below 0.3 Ω) ensures excellent control and compatibility. Adjustable low/high gain and a digital 60-step volume control allow fine tuning for sensitive in-ear monitors as well as more demanding loads.

A replaceable 10440 lithium battery powers the unit, providing up to approximately 7.5–9 hours of playback depending on output and mode, and can be recharged over USB-C in under two hours. The device can also work as a USB dongle DAC when connected to a phone or computer, bypassing Bluetooth entirely for bit-perfect wired playback up to 96 kHz / 16-bit PCM.

Integrated FiiO Control app support unlocks a powerful 10-band PEQ, preset and user EQ profiles, firmware updates, and deep configuration options, while the built-in microphone and CTIA in-line remote support enable voice calls and convenient playback control in Bluetooth mode. With its lightweight body, lanyard-friendly form factor and retro styling, the SNOWSKY Retro Nano is an ideal companion for music lovers who want a fun yet capable all-in-one portable DAC/AMP.
