AirPods Pro 2 的外观变化与召回计划

相信不少读者已经收到 AirPods Pro 2 好几天了，音质之类的不少人都已经测过了，来讲一点外观上的小变化。

AirPods Pro 2 外观一眼看上去只是从一个孔变成两个孔了，但如果你对比一下的话，你会发现其实每个孔都变小了，同时一代下方的传感器消失了。

所以，看起来更像是把一代的两个孔往上平移了一下。如果你再看仔细一点的话，其实变化的不只是位置，还有功能。

二代内侧的孔看起来仅仅有一个接触传感器，辅助降噪麦克风变到了上方的孔中，下方的接触传感器消失了；而一代内侧的孔中包含了一个接触传感器和一个辅助降噪麦克风。

在 AirPods Pro 一代中，耳机经常在使用一段时间后出现降噪故障的情况，会发出啪啪声或者静电声，这种情况不光出现在降噪模式下，也出现在通透模式下。

简而言之，在使用一段时间后，与降噪有关的功能会出现声音故障。为此，Apple 为「2020 年 10 月之前」生产的 AirPods Pro 提供为期三年的召回计划[1]。

造成故障的原因也很简单，一代内侧的辅助降噪麦克风会直接与耳道接触，随着使用时间的增加，耳垢透过表面的滤网渗入辅助降噪麦克风，造成堵塞和故障。

而这颗辅助降噪麦克风则是用于检测耳道内的声音并基于降噪芯片反馈的，所以当它被堵塞，返回错误的信号时，使用了这颗麦克风的功能都会出现影响，甚至你会无法通过耳塞贴合度测试。

苹果可能在后期产品中更换了滤网或者对应的麦克风，因此召回时间被限制到了「2020 年 10 月之前」。

在最新的 AirPods Pro 2 中，这个降噪麦克风被移到了上方的孔中，不直接接触耳道。这种设计对于降噪的精度的影响尚不确定，但大概是可以缓解长期使用出现的堵塞问题。

如果你的 AirPods Pro 一代出现类似的降噪问题的话，临时的解决方案是用蓝丁胶之类的清理内侧降噪麦克风滤网，或者...试试用嘴吸一下（此种方法由他人提供，咱没有测试）。

PS： 即使你是初代首发购买的 AirPods Pro 1，现在也仍然在召回计划服务时间内，如果出现了类似的问题，建议尽快拿去换新。

Telegram Q&A
Q: How does hottg.com work?
Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
