FiiO Echo Nano - Black - Green - Pink - Blue - Titanium - White

Description

Retro Aesthetic and Machined Metal Build

The FiiO Echo Nano borrows the visual language of the iconic perfume-bottle MP3 players of the early 2000s while using contemporary construction techniques. Its miniature chassis weighs just 33.5 g and is CNC-machined from a 6-series aluminum-magnesium alloy. The front carries a 0.91-inch color OLED display that shows tracks and menus with high contrast, and navigation is handled by a metal multi-function scroll wheel on the top of the unit.

High-Resolution Audio Architecture and Native Decoding

Despite measuring only 81 × 20 × 11 mm, the Echo Nano houses an independent Cirrus Logic CS43131 DAC alongside an audio-grade crystal oscillator. This layout enables native hardware decoding of DSD up to DSD256 and PCM up to 24-bit/192 kHz. The player accepts DSD, FLAC, WAV, APE, MP3, M4A, and OGG files. A stated noise floor of 0.7 μV and 0.0006% THD+N contribute to a quiet background between notes.

Expandable Storage and USB DAC Mode

The Echo Nano combines 256 MB of internal flash memory with a MicroSD slot supporting cards up to 256 GB. Alongside local playback, it offers a USB DAC mode using the USB Audio Class 1.0 (UAC 1.0) protocol, which keeps it compatible with older computers and gaming consoles. In USB DAC mode, native decoding is capped at 16-bit/48 kHz — to play high-resolution files without downsampling, the Echo Nano must run from its internal memory or MicroSD card.

Amplification, Battery Life, and Controls

The internal amplification stage delivers 120 mW into 32 ohms on the 3.5 mm single-ended output, with a stated signal-to-noise ratio of at least 127 dB (A-weighted, 32 ohms). This is sufficient for most in-ear monitors and portable headphones. The Echo Nano also supports CTIA in-line remote controls on headphone cables for playback. A 360 mAh rechargeable battery provides up to 7 hours of continuous playback depending on file type and volume.

Common Questions

Which audio file formats are supported?

The Echo Nano supports native DSD decoding (up to DSD256) and PCM up to 24-bit/192 kHz in local playback, along with the DSD, FLAC, WAV, APE, MP3, M4A, and OGG formats.

Can I use it as a USB DAC for a computer or phone?

Yes. In USB DAC mode, the Echo Nano works as a driver-free USB Audio Class 1.0 (UAC 1.0) device on compatible computers, smartphones, and some gaming consoles. USB decoding is capped at 16-bit/48 kHz — to play high-resolution files at full sample rate, use local playback from the MicroSD card or internal memory.

What is the maximum supported storage capacity?

The Echo Nano has 256 MB of internal flash memory and accepts MicroSD cards up to 256 GB.

How does the Echo Nano compare to the FiiO Echo?

The larger Echo model has dual Cirrus Logic CS43198 DACs instead of a single CS43131, adds a 4.4 mm balanced output (260 mW into 32 ohms) alongside the 3.5 mm jack, a 2.39-inch IPS color display instead of the 0.91-inch OLED, Bluetooth 5.3 connectivity, and longer battery life. The Nano stays much lighter (~33.5 g vs 85 g) and keeps the USB DAC mode.
