Suddenly, no one can hear you on your iPhone. Or maybe it’s intermittent, cutting out mid-sentence. You frantically tap buttons, switch to speakerphone, and jab at the volume controls, all while the person on the other end is probably wondering if you’ve simply vanished.

I had this happen last year. I was in a crucial work meeting, and every time I tried to speak, it sounded like I was underwater. The meeting was a disaster. I spent the next hour restarting the phone, fiddling with settings, and feeling increasingly frustrated. The worst part? It was a brand-new iPhone, straight out of the box.

This is a common issue, and if your iPhone can’t hear calls, it can be incredibly irritating. Fortunately, it’s rarely a sign of a terminal problem. Often, it’s a simple fix, one you can probably handle yourself. Let’s dig in.

We will get to the bottom of this.

Is It the Speaker or the Microphone?

Before you start a full-blown troubleshooting session, figure out if the problem is the speaker, the microphone, or both. The easiest way to do this is to make a phone call and try these simple steps:

Listen: Can you hear the other person? If not, the speaker is the issue.
Speak: Ask the other person if they can hear you. If not, the microphone is the problem.
Speakerphone Test: Switch to speakerphone. Can the other person hear you now? If so, the primary microphone might be blocked or damaged.
Headphones Test: Plug in a pair of headphones with a microphone. Does the call work fine? If yes, it’s the iPhone’s microphone or internal components.

Immediately, this helps narrow down the possibilities. For me, it was the microphone. The speaker worked fine. After confirming this, I was able to stop worrying about the speaker.

Another issue I once faced was my own fault. I had a screen protector and a case. I had never noticed that they partially covered the speaker and microphone. A quick removal of both fixed the issue immediately.

Check the Basics: Volume, Mute, and Bluetooth

Often, the simplest solutions are the ones we overlook. Sometimes, the fix is to turn up the volume. Sometimes, it is as simple as pressing a button.

First, check the volume. During a call, use the volume buttons on the side of your iPhone to make sure the call volume is not set to zero. I once spent 20 minutes on the phone with a tech support person before realizing the volume was all the way down. I felt rather foolish.

Next, make sure your iPhone isn’t muted. The mute button is on the side of your phone. There is also a mute button during the call, which might be activated accidentally. Look at the screen during the call for a microphone icon with a line through it. Tap this icon to unmute.

Finally, check your Bluetooth connection. If you’re connected to a Bluetooth device, like a headset or car audio system, the call audio might be routed through that device instead of your iPhone’s speaker and microphone. Turn off Bluetooth on your iPhone or disconnect the Bluetooth device to see if that resolves the issue. I’ve wasted many minutes trying to figure out why my calls sounded terrible, only to realize my AirPods were still connected.

Short. Bluetooth. Check that.

Medium. It can be easy to overlook a simple fix, especially when you’re stressed or in a hurry.

Long. Ensure your phone isn’t connected to any Bluetooth devices, as this can reroute audio and prevent your iPhone from using its built-in speaker and microphone, and sometimes, even when disconnected, a glitch can occur, so it’s worth forgetting the device and re-pairing it, just to be on the safe side, especially if you’re experiencing intermittent audio problems or if your iPhone is struggling to switch between audio sources during a call, which can be super annoying.

Clean the Microphone and Speaker

Dust, debris, and pocket lint are the enemies of good audio. The microphone and speaker on your iPhone are small and easily clogged. If you can’t hear, or others can’t hear you, it’s time to clean things up.

Carefully inspect the speaker and microphone openings on the bottom and top of your iPhone. You’ll probably see some build-up. I always find a small amount of fluff.

Avoid using sharp objects to clean the openings, as you could damage the delicate components inside. Instead, use a soft-bristled brush, such as a toothbrush, or compressed air to gently remove any debris. Be gentle, and don’t push anything further into the openings.

According to the American Consumer Institute, using compressed air is the most effective and safest way to clean small electronics. I have personally found this to be true.

Short.

Short. Check for dust.

Long. You can also use a small amount of isopropyl alcohol on a cotton swab to gently clean the openings, but be extremely careful not to get any liquid inside the phone, because, let’s face it, that’s not good.

Software Troubleshooting: Restart, Update, and Reset

Sometimes, the problem isn’t hardware-related, but software-related. I learned this the hard way after a particularly frustrating weekend. I tried everything, and it turned out to be a software glitch.

Restart Your iPhone: A simple restart can often resolve minor software glitches that might be interfering with your iPhone’s audio. Turn off your iPhone, wait a few seconds, and then turn it back on. This is always the first thing I try now. After my third attempt, it usually works.

Update iOS: Make sure your iPhone is running the latest version of iOS. Software updates often include bug fixes and improvements that can address audio issues. Go to Settings > General > Software Update to check for updates. I have found this to be a consistent issue with older versions of iOS.

Reset Network Settings: Resetting your network settings can sometimes resolve issues with cellular connectivity or Wi-Fi calling, which can affect call audio. Keep in mind that this will remove your saved Wi-Fi passwords, so make sure you have them handy. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.

Here is another trick. I have found, on my third phone, that a forced restart helps. Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the side button until the Apple logo appears. This often solves the problem.

Short. Update. (See Also: Why Has My Camera Stopped Working On My Iphone )

Short. Restart.

Medium. Sometimes the software is the issue, and these basic steps often resolve the issue.

Long. By restarting your iPhone, you force the operating system to close all running applications and processes, which can resolve any temporary glitches or conflicts that might be affecting the microphone and speaker, and updating iOS ensures that you have the latest software updates, which often include bug fixes and improvements related to audio quality and call performance, and finally, resetting network settings can resolve issues with cellular connectivity or Wi-Fi calling that might be interfering with call audio.

Check Your Iphone’s Microphone Permissions

Apps can sometimes interfere with your iPhone’s microphone. Ensure that the apps you’re using for calls (Phone, FaceTime, etc.) have permission to access your microphone. Otherwise, you won’t be heard.

Go to Settings > Privacy > Microphone. Make sure the toggle switch next to the apps you want to use for calls is turned on (green). If the toggle is off, the app won’t be able to access your microphone.

I once had this problem with a third-party calling app. After spending an hour with tech support, it turned out that the app didn’t have access to the microphone. Talk about a facepalm moment.

Hardware Troubleshooting: The Last Resort

If you’ve tried all the software troubleshooting steps and the problem persists, the issue might be hardware-related. This is when things get trickier, and it’s time to consider these options.

Check for Physical Damage: Inspect your iPhone for any signs of physical damage, such as cracks, dents, or water damage. If your iPhone has been damaged, it could affect the speaker or microphone. I dropped my phone in the sink once, and the microphone was never the same.

Try a Different SIM Card: In rare cases, a faulty SIM card can cause call audio issues. If you have another SIM card, try inserting it into your iPhone to see if it resolves the problem. This is a long shot, but worth a try.

Contact Apple Support: If you’re still unable to fix the problem, contact Apple Support or take your iPhone to an Apple Store or authorized service provider. They can diagnose the issue and provide repair options. Honestly, sometimes it’s best to let the experts handle it.

Short. Check for damage.

Short. Contact Apple.

Medium. You might need to consider a hardware fix if the software solutions fail. (See Also: Why Wont My Reminders Work On Iphone )

Long. This is the last resort, as hardware repairs can be costly and time-consuming, but checking for physical damage is crucial, as even small cracks or dents can affect the speaker and microphone functionality, and you should also consider trying a different SIM card, as a faulty SIM card can sometimes cause audio issues, although this is a rare occurrence, and if all else fails, contacting Apple Support or visiting an Apple Store is your best bet, as they have the expertise and tools to diagnose and repair any hardware-related problems.

Comparison: Troubleshooting Steps

Problem	Possible Solution	Verdict/Recommendation
No sound from speaker	Check volume, clean speaker, hardware damage	Try cleaning, if that doesn’t work, contact Apple
No sound from microphone	Check mute, clean microphone, app permissions	Start with app permissions, then clean
Bluetooth Interference	Turn off Bluetooth or forget devices	Definitely try this first
Software issues	Restart, update iOS, reset network settings	Restart first, then update
Hardware damage	Physical inspection, contact Apple	Contact Apple or get a new phone

There is no perfect solution. Sometimes, it is trial and error.
