如果您的 iPhone 耳机无法正常工作，您可以采取一些措施来解决问题。我们将引导您了解它们中的每一个。
iPhone 或 iPod touch 上的耳机是否无法正常工作？也许你什么都听不见。或者它听起来很遥远或闷闷不乐。通过以下故障排除提示来修复 iPhone 耳机声音问题。
1.增加耳放音量
虽然无法将 iPhone 的耳机静音，但您可能不小心将其设置为太低而无法听到的音量。拨打或接听电话时，反复按提高音量按钮以提高音量。
2.选择耳机(Ear Speaker)作为音频目的地(Audio Destination)
如果 iPhone 的耳机没有声音，请确保将其设置为音频目的地，而不是您的 AirPods 或您可能经常使用
的其他蓝牙耳机。(Bluetooth)
为此，请在通话时点击音频图标并选择 iPhone。(Audio)或者，关闭任何蓝牙(Bluetooth)设备或禁用 iPhone 上的蓝牙(Bluetooth)无线电（打开控制中心(Control Center)并点击蓝牙(Bluetooth)图标）。
3. 检查扬声器
的音频(Audio)
蜂窝连接性差(Poor)可能是导致耳机声音微弱、噼啪作响或声音低沉的另一个原因。要确认，请切换到免提——在通话期间点击音频(Audio)图标并选择免提(Speaker)。如果电话听起来相同，那么您必须执行以下操作：
- 启用和禁用飞行模式(Airplane Mode)。
- 移动(Move)到蜂窝接收更好的区域——信号指示器至少应该是半满的。
- 激活 Wi-Fi 通话(Activate Wi-Fi Calling)。
- 转到Settings > General >关于”，然后等待弹出窗口要求您更新运营商设置。
- 联系您的运营商。
如果问题仅出现在网络语音通话（例如，FaceTime或WhatsApp）
上，了解如何修复不稳定的移动数据(fix spotty mobile data)或Wi-Fi 连接。(Wi-Fi connections)
4.禁用手机降噪(Phone Noise Cancellation)
您的 iPhone 使用名为“电话降噪(Phone Noise Cancellation)”的功能来降低环境噪音水平并使通话听起来更清晰。但有时，它可能会出现故障并阻止耳机完全工作。禁用声音设置并检查是否有影响。
为此，请打开 iPhone 的“设置”(Settings)应用程序，转到“Accessibility > Audio/Visual”，然后关闭“电话降噪(Phone Noise Cancellation)”旁边的开关。
5.重启你的 iPhone
重新启动 iPhone 是另一种可以提供帮助的快速修复方法，尤其是在遇到与软件相关的意外故障导致耳机无法工作时。
要重新启动任何 iPhone 型号，请打开“设置”(Settings)应用，点击“General > Shut Down，然后将电源(Power)图标拖到右侧。然后，等待 20-30 秒并按住侧边(Side)按钮，直到看到Apple标志。
6. 清洁耳罩格栅
如果您使用 iPhone 已经有一段时间了，汗水、油污和污垢通常会积聚在耳机格栅中并阻塞音频。使用防静电刷、软毛牙刷或棉签轻轻清洁。避免(Avoid)使用液体——即使是外用酒精——因为这会永久损坏耳机。
7.让你的 iPhone 退出耳机模式(Headphone Mode)
您是否在 iPhone 上使用有线耳机或耳机？即使在取下耳机后，音频也会卡在耳机模式中是很常见的。(Headphone Mode)发生这种情况时，控制中心(Control Center)的音量滑块将显示耳机(Headphone)符号。
尽管可以在通话期间手动切换到耳机，但这可能是一个经常出现的问题，除非您将 iPhone 退出耳机模式(Headphone Mode)。要做到这一点：
- 将耳机插入 iPhone 并再次拔出。
- 使用压缩空气清洁耳机插孔或 Lightning 连接器；不要将喷嘴粘在里面，因为这会损坏内部组件。您也可以用齿间刷撬开任何粘在里面的棉绒或粘稠物。
- 强制重启你的 iPhone(Force-restart your iPhone)。
8. 移除所有屏幕(Screen) 保护膜(Protectors)和保护壳
屏幕保护膜和笨重的保护壳可能会挡住 iPhone 的听筒并使其看起来无法正常工作。尝试在没有任何潜在障碍的情况下拨打电话并检查是否有帮助。
9. 更新你的 iPhone
更新 iPhone 的系统软件是消除导致耳机问题的潜在错误和故障的最佳方法。要安装 iOS 更新，请打开设置(Settings)应用程序，转到General > Software Update，然后点击下载(Download)并安装(Install)。

10. 将 iPhone设置(Settings)恢复出厂设置为默认值
如果 iPhone 耳机的问题仍然存在，我们建议您将所有手机设置重置为出厂默认设置。通常，这可以修复由损坏或损坏的软件配置引起的 iPhone 问题。不用担心，除了保存的 Wi-Fi 网络和密码之外，您不会丢失任何数据。
要在 iPhone 上执行所有设置重置，请在 iPhone 上打开“设置”(Settings)应用，转到“General > Transfer或重置(Reset)iPhone ” > Reset”，然后点击“重置所有设置”(Reset All Settings)。您的 iOS 设备将在此过程中重新启动。
返回主屏幕(Home Screen)后，返回“设置”(Settings)应用并手动连接到您想要重新加入的任何 Wi-Fi 网络。当您使用它时，您可能还想以您喜欢的方式重新配置您的隐私和可访问性选项。您无需对蜂窝设置进行任何操作，因为 iOS 会自动配置它们。
11. 在Apple(Apple) Store
预约
如果上述修复都不能帮助修复您的 iPhone 耳机，您可能正在处理硬件问题。因此，请联系 Apple 支持并在最近的(contact Apple Support)Genius Bar 天才吧(Genius Bar)预约。
同时，你也可以自己动手，在 DFU 模式下重新安装 iPhone 的固件(reinstall the iPhone’s firmware in DFU Mode)。
iPhone Ear Speaker Not Working? Try These 11 Fixes
If your iPhone’s ear speaker is not functioning correctly, thеre are a few things you can do to fix the рroblem. We will wаlk you through each of them.
Is the ear speaker on your iPhone or iPod touch not working? Perhaps you don’t hear anything. Or maybe it sounds distant or muffled. Go through the following troubleshooting tips to fix iPhone ear speaker sound issues.
1. Increase the Ear Speaker Volume
Although it’s impossible to mute your iPhone’s ear speaker, you may have accidentally set it at a volume level that’s too low to hear. While making or answering a call, press the Volume Up button repeatedly to increase the volume.
2. Select Ear Speaker as Audio Destination
If there’s no sound coming out of the iPhone’s ear speaker, ensure it’s set as the audio destination and not your AirPods or another Bluetooth headset you might be using regularly.
To do that, tap the Audio icon while on a phone call and select iPhone. Alternatively, turn off any Bluetooth devices or disable the Bluetooth radio on your iPhone (open the Control Center and tap the Bluetooth icon).
3. Check the Audio for the Speakerphone
Poor cellular connectivity can be another reason for a weak, crackling, or muffled-sounding ear speaker. To confirm, switch to speakerphone—tap the Audio icon during a phone call and select Speaker. If phone calls sound the same, here’s what you must do:
- Enable and disable Airplane Mode.
- Move to an area with better cellular reception—the signal indicator should be at least half full.
- Activate Wi-Fi Calling.
- Go to Settings > General > About and wait for a pop-up that asks you to update your carrier settings.
- Contact your carrier.
Learn how to fix spotty mobile data or Wi-Fi connections if the issue only occurs on voice-over-the-internet calls (e.g., FaceTime or WhatsApp).
4. Disable Phone Noise Cancellation
Your iPhone uses a feature called Phone Noise Cancellation to reduce ambient noise levels and make phone calls sound clearer. But sometimes, it can bug out and stop the ear speaker from working altogether. Disable the sound setting and check if that makes a difference.
To do that, open the iPhone’s Settings app, go to Accessibility > Audio/Visual, and turn off the switch next to Phone Noise Cancellation.
5. Restart Your iPhone
Restarting your iPhone is another quick fix that can help, especially when it comes to unexpected software-related glitches preventing the ear speaker from working.
To reboot any iPhone model, open the Settings app, tap General > Shut Down, and drag the Power icon to the right. Then, wait 20-30 seconds and hold down the Side button until you see the Apple logo.
6. Clean the Ear Speaker Grill
If you’ve been using your iPhone for some time, it’s common for sweat, oil, and dirt to accumulate in the ear speaker grill and block audio. Gently clean it using an anti-static brush, a soft-bristled toothbrush, or a Q-tip. Avoid liquids—even rubbing alcohol—since that can permanently damage the ear speaker.
7. Get Your iPhone Out of Headphone Mode
Do you use wired earphones or headphones with your iPhone? It’s common to have the audio stuck in Headphone Mode even after removing your headset. The Volume slider in the Control Center will display a Headphone symbol when that happens.
Although it’s possible to switch to the ear speaker manually during a phone call, that can be a recurrent problem unless you get your iPhone out of Headphone Mode. To do that:
- Plug your headphones into your iPhone and out again.
- Clean out the headphone jack or Lightning connector using compressed air; do not stick the nozzle inside since that can damage internal components. You can also pry any lint or gunk stuck inside with an interdental brush.
- Force-restart your iPhone.
8. Remove All Screen Protectors and Cases
Screen protectors and bulky cases can block your iPhone’s earpiece and give the appearance of it not working. Try making a phone call without any potential obstructions and check if that helps.
9. Update Your iPhone
Updating your iPhone’s system software is the best way to eliminate underlying bugs and glitches that cause ear speaker issues. To install iOS updates, open the Settings app, go to General > Software Update, and tap Download & Install.

10. Factory-Reset iPhone Settings to Defaults
If the problem with your iPhone’s ear speaker persists, we recommend you reset all phone settings to their factory defaults. Usually, that fixes iPhone issues caused by a corrupt or broken software configuration. Don’t worry—you won’t lose any data except for saved Wi-Fi networks and passwords.
To perform an all settings reset on the iPhone, open the Settings app on your iPhone, go to General > Transfer or Reset iPhone > Reset, and tap Reset All Settings. Your iOS device will restart during the process.
Once you’re back on the Home Screen, head back to the Settings app and manually connect to any Wi-Fi networks you want to rejoin. While you’re at it, you may also want to re-configure your privacy and accessibility options the way you prefer. You don’t have to do anything about your Cellular settings since iOS configures them automatically.
11. Book an Appointment at an Apple Store
If none of the fixes above help fix your iPhone ear speaker, you’re likely dealing with a hardware issue. So, contact Apple Support and book an appointment at the nearest Genius Bar.
In the meantime, you can also take matters into your own hands and reinstall the iPhone’s firmware in DFU Mode.
