Gear Patrol[3] 的发布报道(https://www.gearpatrol.com/audio/sonos[4]-ace-ultra-announcement-price-availability/)与 Sonos 新闻室均表示,售价 449 美元的 Ace Ultra 在 9 月 1 日发布后,于 2026 年 9 月 29 日开始发货。该发货日期被用作此 pin 的日期。
Bloomberg's own headline, "Sonos[1][4] Debuts $449 Ace Ultra Headphones, $699 Beam Ultra Soundbar, ChatGPT Tie-In," published 1 September 2026, matches the pin's claim and predates the pin's stored 8 September 2026 roundup date, though the article itself returned a 403 error and could not be retrieved.
Gear Patrol confirms the Ace Ultra is priced at $449 with shipping beginning 29 September 2026 and new "Headphone Linking" functionality, matching the pin's description and its roundup-sourced date.
Sonos's[1] own press release says Sonos Ace Ultra "will be available for pre-order starting September 1, 2026" at $449 "with general availability on September 29, 2026", and is the first headphone built on Headphone Engine 2.
