Sound
SnowSky Retro Nano offers impressive speed, accuracy, and a commendable layering capability. The audio quality is natural, featuring rich low frequencies and clear mid-range tones. Its performance in micro-detail is exceptional, providing a well-balanced sound signature for an enjoyable listening experience.
The bass is impressive. It’s fast and powerful and with good headphones, you’ll be rewarded by deep and tight bass. And it never oversteps on the other frequencies. Midbass is also very well-judged and doesn’t color the midrange.
The midrange is full and lush with a rich timbre. Instruments have a full body and weight, and vocals are rendered similarly. This full-bodied core is overlaid with an open upper midrange that adds a layer of texture and brightness, making for quite a balanced and natural tonality. This creates a sensation of an open and texture-rich tone.
The vocals sound with perfect tonality and timber for my ears and the Retro Nano gave me a good level of clean sound. Mids have excellent layering and great spaciousness. They blend perfectly with the rest of the spectrum.
The Treble area sounds clean and transparent. It is extended, airy, and spacious without any control issues. In my opinion, the Retro Nano raises the bar in the $100 segment with sharp, harsh-less trebles, and excellent layering at any given volume.
With the right headphones, you’ll get a level of power and accuracy that you won’t expect from a DAC at this price. You get it all with the SnowSky Retro Nano through micro-details, balanced signature, and precise timbre.
Moving on to technicalities, it’s exceptionally well-developed for a product of this size and price. The soundstage is surprisingly good even at the highest level of volume. Compared to some budget USB DACs the mids don’t tend to fall behind the highs and lows, and everything sounds pretty even.

All tones have plenty of room to breathe and are arranged in front of a very black background. Pinpointing a source where the sound originated is easy, but SnowSky Retro Nano avoids ever becoming tiring in any way imaginable.
The Retro Nano seems to take a step forward in imaging capabilities plus added placement accuracy from let’s say the first iteration dongle DACs that were introduced into the market which generally sounded somewhat narrow and lacked depth.
Sum-Up
Dual CS43131 DACs, Hi-Res Bluetooth LDAC, aptX Adaptive, aptX LL codec support, 0.96” Color Display, 220mW output power and removable battery. Did I mention the amazing FiiO App support including Parametric EQ? And you get all of these features just for $59.99.
I don’t know how FiiO pulled out this kind of price/performance ratio but this is a real game-changer device for this price. Just get one and live a happy life.
