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.
JBL's own press release (https://news.jbl.com[3]/en-CEU/269714-jbl-launches-jbl-cove-a-new-whole-home-audio-system-to-enjoy-superior-sound-throughout-the-entire-home/) announces the Cove range on 1 September 2026 and states the speakers 'launch in white and black at JBL.com starting October 8, 2026'. That maker-stated availability day is used as the pin date.
SoundGuys, published September 2, 2026, reports on the same announcement but notes 'an exact release date hasn't been announced' at that time, close to the pin's stored September 8, 2026 date though without confirming a specific ship date.
JBL's own press release states the Cove lineup was introduced September 1, 2026, just before the pin's stored September 8, 2026 date, with the speakers set to 'launch in white and black at JBL.com[1] starting October 8, 2026.'
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.
