AirPods 的固件包含复杂的硬件级编程，允许每个内部组件正常运行。它也是可升级的。因此(Hence)，Apple发布了更新版本的固件，它们通常包含错误修复、性能增强和（在较小程度上）功能添加。
根据设计，您的 AirPods、AirPods Pro或AirPods Max会在您不知情的情况下通过您的 iPhone 自行更新。但如果这未能发生，您可能需要自己动手并手动强制更新固件。
为什么要更新 AirPods 的固件(Firmware)
大多数情况下，您的 AirPods 应该会在新固件发布后的几天内自动更新。但是，以下是您应该主动检查和更新固件的几个原因。
在 AirPods 上遇到的问题(Encountering Issues on AirPods)
AirPods 可与 iPhone 和iPad 和Mac等其他(Mac)Apple设备完美配合。但是，如果您的无线耳塞或耳机开始出现异常行为（随机断开连接、麦克风故障、只有一个 AirPod 工作(only one AirPod working)等），那么固件更新可能正是他们所需要的。
当然，这是假设您已经完成了与该问题相关的任何适用修复程序。
AirPods 缺少的功能(Missing Features on AirPods)
AirPods 可以通过固件更新接收功能添加。例如，AirPods Pro上的空间音频(Spatial Audio)（提供环绕声和 3D 音频）仅适用于固件更新 3A283 和更新版本。
因此，如果您发现iPhone 上 AirPods 的蓝牙设置中(AirPods’ Bluetooth settings on your iPhone)缺少某个特定功能，那么您可能运行的是过时版本的固件。
如何查看AirPods 固件版本(AirPods Firmware Version)
在尝试升级AirPods上的固件之前，请检查固件版本。更新也可能自动发生。以下步骤可以帮助您了解AirPods（第 1 代和第 2 代）、AirPods Pro和AirPods Max上的当前固件版本。
1. 将AirPods连接到您的 iPhone。
2. 打开 iPhone 的设置(Settings )应用程序。
3. 点击常规(General )>关于(About)。
4. 向下滚动并点击[Your Name] 的 AirPods([Your Name]’s AirPods)。
5. 记下固件版本(Firmware Version)旁边的内部版本号。
Apple不提供官方文档供您参考以检查特定于您的 AirPods 的最新固件版本。但是在Google中简单搜索“[AirPods 型号] 的最新固件版本”应该可以帮助您快速找出答案。
如果您的 AirPods 上的固件出现过时，下一节中的说明应该可以帮助您更新它。
如何更新 AirPods 固件
您不会在 iPhone 上找到启动无线AirPods固件更新的选项或开关。但是，您可以设置您的AirPods和 iPhone 以触发更新。
您不必做任何复杂的事情，以下步骤几乎一直有效。它们适用于AirPods（第 1 代和第 2 代）、AirPods Pro和AirPods Max。
1. 将您的 iPhone 连接到 Wi-Fi 网络。
2. 确保iOS 设备上的低功耗模式(Low Power Mode)和低数据模式(Low Data Mode)未激活。
3. 将AirPods放入充电盒(Charging Case)、无线充电盒(Wireless Charging Case)或智能盒(Smart Case)中。然后，将AirPods连接到电源并等待它们充电 50% 或更多。您可以使用 iPhone 的电池小部件(using your iPhone’s Batteries widget)检查电量。
4. 将 iPhone 放在AirPods(AirPods)旁边，让两台设备单独放置至少 30 分钟。固件应同时更新。
5. 进入设置(Settings )>通用(General )>关于(About )> [你的名字] AirPods([Your Name] AirPods)并再次检查固件版本(Firmware Version )以确认更新已经发生。
但是，如果固件版本与以前相同，则将 iPhone 和AirPods彼此相邻放置较长时间（例如，过夜）会有所帮助。最好将 iPhone 连接到充电器。
注意：(Note:) AirPods也适用于Android手机。但由于Apple使用 iOS 作为更新AirPod固件的桥梁，Android手机将无法做到这一点。如果您不想停留在原始固件上，请让拥有 iPhone 的人为您更新AirPods。
无法更新(Update)AirPods 的固件？重置(Reset)并重试(Try Again)
如果您无法让AirPods上的固件更新，请尝试重置它们并将其重新连接到您的 iPhone。AirPods（第 1 代和第 2 代）和AirPods Pro的程序相同，但在AirPods Max上略有不同。完成后，再次重复上一节中的说明。
重置 AirPods（第一代和第二代）和 AirPods Pro(Reset AirPods (1st and 2nd Gen) and AirPods Pro)
1. 将AirPods放入充电盒(Charging Case)或无线充电盒(Wireless Charging Case)。
2. 合上盖子，等待几秒钟，然后重新打开。
3. 按住设置(Setup )按钮，直到机箱的状态指示灯呈琥珀色闪烁。
4. 合上盖子并重新打开。
5. 点击连接(Connect )以将AirPods重新连接到您的 iPhone。
重置 AirPods Max(Reset AirPods Max)
1. 将您的AirPods Max放入Smart Case中。
2. 同时按住Digital Crown和Noise Control按钮，直到状态指示灯呈琥珀色闪烁。
3. 将 AirPods Max从Smart Case中取出，然后在 iPhone 上点击连接。(Connect )
让您的 AirPods 保持更新
除非您在 AirPods 上不断遇到问题或缺少功能，否则您不必特意启动固件更新。相反，只需继续正常使用它们，它们应该会自动更新。

How to Update the AirPods Firmware and Why You Should
The AirPods’ firmware consiѕts of complex hardware-level programming that allowѕ for each internаl compоnent to function correctly. It’s also upgradеable. Hence, Apple releasеs newer versіons of the firmware, and they often contain bug fixes, performance enhanсements, and (to a lesser extent) feature additions.
By design, your AirPods, AirPods Pro, or AirPods Max update themselves via your iPhone without you even knowing. But if that fails to happen, you may want to take matters into your own hands and force-update the firmware manually.
Why You Should Update Your AirPods’ Firmware
Most of the time, your AirPods should automatically update within a few days of a new firmware release. However, here are a couple of reasons why you should actively check for and update the firmware.
Encountering Issues on AirPods
AirPods work flawlessly with the iPhone and other Apple devices such as the iPad and Mac. But if your wireless earbuds or headphones start to exhibit unusual behavior (random disconnects, microphone failures, only one AirPod working, etc.), a firmware update may just be what they need.
Of course, that’s assuming you’ve already finished working your way through any applicable fixes related to the issue.
Missing Features on AirPods
AirPods can receive feature additions via firmware updates. For instance, Spatial Audio on the AirPods Pro (which delivers surround sound and 3D audio) only works with firmware update 3A283 and newer.
So if you find a particular feature missing within the AirPods’ Bluetooth settings on your iPhone, you’re likely running a dated version of the firmware.
How to Check the AirPods Firmware Version
Check the firmware version before attempting to upgrade the firmware on your AirPods. The update could have happened automatically too. The following steps should help you figure out the current firmware version on the AirPods (1st and 2nd generations), AirPods Pro, and AirPods Max.
1. Connect the AirPods to your iPhone.
2. Open the iPhone’s Settings app.
3. Tap General > About.
4. Scroll down and tap [Your Name]’s AirPods.
5. Note down the build number next to Firmware Version.
Apple does not provide official documentation that you can reference to check the latest firmware version specific to your AirPods. But a brief search in Google for “latest firmware version for [AirPods model]” should help you figure that out quickly.
If the firmware on your AirPods appears out of date, the instructions within the next section should help you update it.
How to Update the AirPods Firmware
You won’t find an option or a toggle on your iPhone to initiate an over-the-air AirPods firmware update. However, you can set up your AirPods and iPhone in a way that can trigger the update.
You don’t have to do anything complicated, and the steps below work almost all the time. They apply to the AirPods (1st and 2nd generations), AirPods Pro, and AirPods Max.
1. Connect your iPhone to a Wi-Fi network.
2. Ensure that Low Power Mode and Low Data Mode are not active on the iOS device.
3. Put your AirPods inside the Charging Case, Wireless Charging Case, or Smart Case. Then, connect the AirPods to a power source and wait until they’ve charged 50% or more. You can check the charge level using your iPhone’s Batteries widget.
4. Place your iPhone right next to the AirPods and leave both devices alone for at least 30 minutes. The firmware should update in the meantime.
5. Go to Settings > General > About > [Your Name] AirPods and check Firmware Version again to confirm that the update has taken place.
However, if the firmware version appears the same as before, leaving the iPhone and the AirPods next to each other for an extended amount of time (say, overnight) can help. It’s also best to hook up your iPhone to its charger.
Note: AirPods work with Android phones as well. But as Apple uses iOS as the bridge to update the AirPod firmware, an Android phone won’t be able to do the same. If you don’t want to stay stuck on the original firmware, ask someone with an iPhone to update the AirPods for you.
Can’t Update the AirPods’ Firmware? Reset and Try Again
If you can’t get the firmware on your AirPods to update, try resetting and reconnecting them to your iPhone. The procedure is the same for the AirPods (1st and 2nd generations) and AirPods Pro, but slightly different on AirPods Max. Once you’ve done that, repeat the instructions in the previous section again.
Reset AirPods (1st and 2nd Gen) and AirPods Pro
1. Put your AirPods inside the Charging Case or Wireless Charging Case.
2. Close the lid, wait for a few seconds, and re-open it.
3. Press and hold the Setup button until the case’s status indicator flashes amber.
4. Close the lid and reopen it again.
5. Tap Connect to reconnect the AirPods to your iPhone.
Reset AirPods Max
1. Put your AirPods Max inside the Smart Case.
2. Press and hold the Digital Crown and the Noise Control button together until the status indicator flashes amber.
3. Take your AirPods Max out of the Smart Case and tap Connect on your iPhone.
Keep Your AirPods Updated
Unless you keep experiencing constant issues or missing features on your AirPods, you don’t have to go out of your way to initiate a firmware update. Instead, just continue to use them normally, and they should update automatically.
Now that you’ve upgraded the firmware (or figured out that you don’t have to), check out these 19 tips to improve the AirPods experience.
