#439 FiiO Snowsky Oak Nano: $499.99 Amazon $499.99 eBay
Pros: A titanium shelled 13.8 mm beryllium alloy dynamic IEM at about $500 with a preference score of 75 across two measurements. The midrange stays within 1.5 dB of target, and the cable swaps between 3.5 mm, 4.4 mm and USB C plugs.
Cons: Sub bass is 4.4 dB below target, so the lowest notes are light. Treble is jagged, with a 6.8 dB dip near 6.3 kHz and peaks of 5.0 dB near 7.9 kHz and 5.6 dB near 11.2 kHz, which can add glare on some recordings.
Is the FiiO Snowsky Oak Nano right for you?
Buy it if
- you want the tuning most listeners prefer in blind tests out of the box (Harman score 75).
- you are sensitive to bright or sharp treble (treble sits 2.4 dB below target).
Skip it if
- you want more bass (about 2 dB below target).
- you want the best value: the higher-rated QCY HT05 MeloBuds ANC costs about $466 less.

Frequency Response
How the FiiO Snowsky Oak Nano measures across the audible range, against the Harman in-ear target that most listeners prefer in blind tests. Where the line sits above the target that range sounds louder (more bass, brighter treble), below it quieter. The curve is the average of 2 independent measurements, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: the average of 2 independent measurements from the squig.link databases of atechreviews and audioamigo. Thanks to each of them for publishing their work.
