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.
The Olive Gray colourway went on sale the day Sony[2] announced it. Sony's own press centre release (https://www.sony.co.uk/presscentre/sonys-new-olive-gray-wh-1000xm6-combines-premium-noise-cancellation-with-refined-design) is dated August 3, 2026, and SoundGuys[3][4]' same-day report (https://www.soundguys.com/sony-wh1000xm6-olive-gray-launch-160886/) says it 'can be purchased from Sony's website and Amazon for $459.99 right now'. August 3, 2026.
Sony's[1] own UK press release is the primary announcement source, with a stored publish date of 3 August 2026 - over a month before the pin's stored 8 September 2026 date, consistent with the item having launched earlier and simply appearing in a later roundup; a 403 error blocked retrieval of the release text.
SoundGuys[4] confirms Sony[1][2] "introduced the Olive Gray color" with a stored publish date of 3 August 2026, predating the pin's stored 8 September date by about five weeks, again consistent with the pin capturing a later roundup mention rather than the original launch.
SoundGuys[3]' launch report for the WH-1000XM6 says "Foldability is back" with "a new metal hinge component", detachable earpads, "At 254g", codecs "SBC, AAC, LDAC, and LC3" with Bluetooth 5.3 and Auracast, and no aptX, USB-C audio or IP rating.
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.
