FiiO has released the ECHO NANO, a pocket player under its SNOWSKY sub-brand. There is a scroll wheel on top, a 0.91-inch screen on the front, and the music sits on a memory card rather than in the cloud. This is the same SNOWSKY whose Wind Pro we covered a week ago. The hardware is not decorative: a dedicated CS43131 DAC chip is installed inside, hardware DSD256 decoding is declared, and the player itself can work as an external sound card for a phone or a computer.
- Dedicated CS43131 DAC chip, hardware DSD256 decoding
- PCM up to 24-bit / 192 kHz, Hi-Res Audio certified
- 0.91-inch OLED display
- Housing made of 6-series aluminium-magnesium alloy, CNC machined
- microSD cards up to 256 GB: DSD, WAV, FLAC, APE, MP3, M4A, OGG
- USB Audio Class mode — the player works as an external sound card

Controls. A metal wheel is placed on the top edge: scrolling changes the volume, pressing turns the power on and activates the screen. FiiO puts the emphasis on the fact that the player can be operated by touch, without taking it out of a pocket. In external sound card mode charging can be switched off so that the device does not drain the phone battery.
What was not announced. The official page lists neither battery life, nor weight, nor dimensions, nor output power, nor the price. The specification table at FiiO is drawn as an image, and these numbers do not exist anywhere as text. For a pocket player battery life and power are basic questions, and there is no answer to them.
ECHO NANO
- One CS43131 DAC chip
- DSD256, PCM 24-bit / 192 kHz

- Output power not announced
- Battery life not announced
ECHO MINI
- Two ES9068AS DAC chips, one per channel

- Colour IPS display
- 512 MB or 8 GB of memory plus microSD

- More than 15 hours of playback, Bluetooth 5.3
The neighbouring ECHO MINI model is better equipped on paper: it has two DAC chips, 250 mW of power, a 4.4 mm balanced output, Bluetooth and an 1100 mAh battery. The NANO has none of that, but it does have the wheel and a body that fits into a palm completely.
What we will check. The questions are exactly the ones the official page does not answer: how long the player really runs on a charge and whether the CS43131 has enough power for anything heavier than in-ear headphones. Our test will show whether it copes. From our experience with this sub-brand see the Wind Pro story — that model follows the same retro line, but it is a pair of on-ear headphones rather than a source.
Do you carry a separate source or have you moved to a phone with an external DAC? Tell us in the comments — and which player was the last one you did not want to part with.
