FiiO ECHO NANO — Ultra-Portable HiFi MP3 Player & USB DAC

"Retro Soul. Hi-Res Heart. Fingertip Control."

The FiiO ECHO NANO is a tribute to the iconic “perfume bottle” MP3 era — reimagined as a modern Hi-Res audio player. Part of FiiO’s SNOWSKY sub-brand retro series, the ECHO NANO packs a Cirrus Logic CS43131 DAC chip, DSD256 native decoding, and a fingertip scroll wheel into an ultra-lightweight 33.5g aluminum-magnesium alloy body. It also doubles as a USB DAC for your phone, tablet, or PC — plug in and instantly elevate your listening experience.

Key Features

• Retro Design, Modern Soul — Inspired by Sony’s classic “perfume bottle” MP3 players, the ECHO NANO revives the charm of the millennium era in a sleek, pocket-sized form. The CNC-machined 6-series aluminum-magnesium alloy shell is precision-crafted for a refined, wear-resistant finish that feels as good as it looks.
• Fingertip Scroll Wheel Control — A metal multi-function scroll wheel sits at the top of the device. With one hand, you can adjust volume, power on/off, and wake/sleep the screen — smooth, precise, and intuitive even without looking.
• 0.91" OLED Display — The self-emissive OLED screen delivers crisp, clear track and playback information while consuming minimal power — helping extend battery life without sacrificing readability.
• CS43131 DAC Chip — Hi-Res Audio — The dedicated Cirrus Logic CS43131 DAC chip supports native PCM 24-bit/192kHz and DSD256 decoding, delivering immersive, high-fidelity sound with an SNR of ≥127dB, THD+N of just 0.0006%, and an ultra-low noise floor of 0.7µV.
• USB DAC Mode (UAC) — Connect the ECHO NANO to your smartphone, tablet, or PC via USB-C to use it as a high-performance external sound card. Plug-and-play, no drivers needed. UAC mode also supports disabling charging to eliminate battery anxiety during use.
• Wide Format Support & TF Card Storage — Supports DSD, WAV, FLAC, APE, MP3, M4A, and OGG formats. Expandable via TF card up to 256GB — carry thousands of lossless tracks wherever you go.
• Headphone Remote Control Compatible — Supports standard (CTIA) headphone inline remote controls for play/pause, track skipping, and volume adjustment — perfect for on-the-go listening without touching the device.
