The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
No source states a release day. FiiO's[2][3] own news post announcing the Snowsky Nature as 'Now Officially Available' carries no date, and Notebookcheck's[5] arrival article, published July 22, 2026 (https://www.notebookcheck.net/Fiio-Snowsky-Nature-heaphones-arrive-with-carbon-black-diaphragms-and-faux-wood-grain.1348848.0.html), reports them as already on sale through FiiO's AliExpress store. Dated to that day, July 22, 2026, as the earliest day they are documented as on sale; this is an estimate, not a stated release date.
FiiO's[3] own launch announcement describes the tuning ("8 rounds of driver parameter iteration and 15 rounds of acoustic chamber refinement, plus nearly 1,000 pieces of real-world listener feedback") and the low-impedance, high-sensitivity design for smartphones and USB dongles.
FiiO's[2] NATURE product page gives the 50mm driver and the diaphragm's "built-in UV and hydrolysis resistance" with a "Fatigue life test >=100,000 cycles, with performance degradation under high temperature and humidity less than 5%".
The Audiophile Man, published 19 August 2026, covers the same Snowsky Nature headphones about three weeks before the pin's stored 8 September 2026 date, again consistent with a pre-launch announcement.
Notebookcheck's own 22 July 2026 publish date on the Fiio[2][3] Snowsky Nature headphones predates the pin's stored 8 September 2026 date by about seven weeks, consistent with an early product announcement ahead of wider retail availability.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
