苹果进入降噪耳机市场的想法也并非无迹可寻。

2014 年,苹果斥资 30 亿美元收购了耳机品牌 Beats,这是苹果有史以来规模最大的一次收购,Beats 的加入也成为苹果进入高端耳机市场的敲门砖。随后分别在 2016 年和 2017 年登场的 AirPods 和 HomePod 则进一步帮助苹果在音乐硬件领域站稳脚跟。去年,调查机构 Counterpoint Research 就曾发布一份报告,指出苹果在 2018 年卖出大约 3500 万副 AirPods 无线耳机,AirPods 逐渐成为 Hearable(智能耳戴式设备)的代表。前有 Beats 负责高端时尚耳机市场,后有 AirPods 和 HomePod 占领真无线耳机和智能音箱市场。目前,苹果缺的正是一款足够优秀的降噪耳机。
