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 gives an exact on-sale day. Gear Patrol's[3][5] piece of September 10, 2026 (https://www.gearpatrol.com/audio/fosi-audio[2]-disc-nano-portable-cd-player/) says 'Fosi Audio's Disc Nano CD player will be available later this month. It'll cost $99', i.e. it had not yet gone on sale. Dated to the last day of the stated month, September 30, 2026, as an estimate.
Fosi Audio's[1] product page lists the DISC Nano at $99.99 and gives "At just 102mm across", an 800mAh USB-C battery, the Cirrus Logic CS43198 DAC with 3.5mm, 4.4mm and optical outputs, ESP anti-shock, the N52 magnet ring ("no wireless charging"), weight 210g and dimensions 102x102x29mm.
Gear Patrol's[5] running roundup includes the Disc Nano as "the company's first-ever portable CD player" with "a MagSafe ring mount", listed at "$99 at Fosi Audio[1][2]".
TechPowerUp's own headline reports Fosi Audio[1][2] expanding its lineup with four new products, plausibly including the Disc Nano referenced by the pin, though the article carries no listed publish date and returned a 403 error, so it could not be fetched directly to confirm the CD player specifically.
Gear Patrol's[3] own review describes the Fosi Audio[1][2] Disc Nano as 'the world's smallest portable CD player,' launching at $99 with its distinctive half-exposed design and MagSafe ring mount - matching the pin's description, though the piece frames the launch as imminent ('later this month') rather than already available as of the pin's stored 8 September 2026 date.
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.
