没有来源给出确切的开售日期。索尼2026年9月7日的官方新闻稿（https://sony.mediaroom.com[3]/2026-09-07-Sony-Electronics-Introduces-WH-1000XM4C-M4-2nd-Gen-Wireless-Noise-Cancelling-Headphones-and-Updates-Popular-Mid-and-Entry-Level-Wireless-Headphones-with-WH-CH730N-and-WH-CH530）称WH-CH730N“自2026年9月起”发售，而Engadget[4]对同一稿件的报道称索尼“将在本月发货WH-CH730N”。作为估计，日期定为所述月份的最后一天，即2026年9月30日。
What Hi-Fi's own headline, "Sony[1] has finally upgraded its budget five-star wireless headphones range," backs the pin's claim about an updated Sony budget model from a respected audio review outlet, though the article body itself could not be retrieved to confirm the specific battery or ANC specs.
Sony's[1] own press release, published 7 September 2026, one day before the pin's stored date, confirms the WH-CH730N update with "improved call quality, and longer battery life from its predecessor," though it cites "up to 50 hours" battery life rather than the 75 hours in the pin's description - a discrepancy worth noting.
Engadget's launch report says the WH-CH730N "promises up to 10 percent less noise through a revised ANC system", adds 10-band and gaming EQs, background music mode and a new safe listening mode.
