If you don’t hear any sounds from your iPhone’s speaker or if it’s muffled, go to Settings > Sounds and drag the Ringer and Alerts sliders in opposite directions. If your speaker button is dim, your product may require service. You can also solve the problem by increasing the volume.

Once you’ve determined that the volume controls and ringer alerts aren’t the source of your iPhone’s problem, here are some other areas to investigate in order to get your smartphone back up and running.

1. Is It A Software Problem?

If your iPhone speakers stopped working in the middle of a streaming session or app activity, a software problem could be to blame. Although Apple products are excellent at detecting a malfunctioning cycle, some of them can cause errors that permanently disrupt the communication loop.

Most software issues can be resolved by turning off the iPhone, waiting about five minutes, and then turning it back on. After it completes the reboot, you should hear the speakers return to normal operation.

If a simple on-off reset doesn’t work, you’ll want to back up your device to iCloud, another computer, or an external drive before continuing. That step will preserve your information. You can back up your iPhone using iCloud by following these steps.

  • Navigate to the Settings menu. Locate your name, then select iCloud, then iCloud Backup.
  • Enable iCloud Backup. This step ensures that your device is automatically backed up when it is plugged in, locked, and connected to a Wi-Fi signal.
  • You can perform a manual backup by selecting Back Up Now.
  • You can manage your backups by going to Settings, Your Name, iCloud, Manage Storage, and Backups. You can remove them from the list by selecting the one you want and then selecting the Delete Backup command.

If you have an Apple computer, you can use a cable to connect your iPhone to it. Locate it using the Finder, then click General, and then select the option that backs up all of the device’s data. Following this step, you can even encrypt it.

You must be in the iTunes app on a Windows PC or an older version of macOS. After you’ve located the iPhone, click Summary. This will navigate you to the Back Up Now command.

2. What Are Your Phone’s Settings?

Is your iPhone on silent mode? When you toggle this command on the side of your device or in the Settings menu, the speakers will no longer make noise when you receive notifications. This problem will allow you to hear audio from your apps, games, and streaming services.

You’ll want to make sure the ring (silent) switch isn’t turned on. If you move it, the volume button should return to its original position.

If you don’t hear any sound, check the volume indicator while pressing the up or down buttons on the iPhone’s side. If you see a crossed-out circle beneath the speaker, it is possible that a hardware or connectivity issue is causing your issue.

3. Is Your Iphone On Mute?

It’s possible that your iPhone’s speakers are muffled due to your volume settings. It can be difficult to hear some output when the device is on the lower audio tier. Try increasing the volume by unlocking the device and holding down the top volume button.

Continue to depress the top volume button on the left until the indicator bar is completely filled. You can also change the volume on your iPhone by going to Settings > Sound and Haptics. Under the Ringer and Alerts heading, move the slider.

To maximize your sound settings, move the toggle to the right. If the volume controls on the phone’s left side aren’t working properly, you can enable the switch next to the Change with Buttons setting.

4. Remove The Iphone From Its Case

If you’re using an iPhone case, the covering may be distorting the sounds you hear. Some products obstruct the speaker output, reducing the audio to the point where it sounds muffled. Some people have this problem when they put their iPhone in its case upside down.

If you remove the device and the muffled audio disappears, check the case instructions to ensure you’re using it correctly. This problem can occur if you use a case designed for a different iPhone model than the one you own. Please remember to double-check compatibility before placing an order.

5. Clean your iPhone

When you pick up your iPhone, the speaker area should have clear sound holes that transmit the audio from the device. If those spaces are filled with junk, you can get a muffled sound. Here are some of the best ways that you can clean your phone at home without damaging it.

Unused ToothbrushUse a clean toothbrush that hasn’t been in your mouth to clean away the dirt, lint, or other debris.Even if you soak the bristles in alcohol before using them, there is a risk that bacteria or other unwanted items could get into the device.
Compressed AirWhen you gently blow out the speaker holes in your iPhone’s case, you can often correct audio issues.This option works well if you have compact debris that doesn’t brush away.
Microfiber ClothA microfiber cloth can pick up the dirt from your speaker area if it is still loose.Some phone-friendly cleaning agents on the material can capture the stubborn stuff that could be leading to the performance issues you’re trying to correct.
Anti-static wipesStatic electricity can ruin the interior components of an Apple device quickly.If you don’t have the other items available to clean your phone, consider grabbing this product to wipe away the offending materials.
ToothpicksIf you carefully use the tip of a toothpick to clean out the gunk from your speakers, you can use the other methods to finish the job.This option works well when the materials are so packed in the frame that nothing else touches it.

6. Put your iPhone in DFU Mode

Before you take your iPhone to an Apple Store for service, you should consider putting it in DFU Mode. This option determines whether your speaker is broken or in need of a rest. The DFU restore is the final step to rule out a software issue.

Back up your iPhone before beginning this process. When you finish this option, DFU mode erases and reloads your iPhone code. You’ll lose photos, messages, contacts, and other data if you don’t have a recent backup.

The majority of the information available online about using DFU for iPhone restoration is incorrect. That is why, in order to have a successful experience, you should follow these steps.

  • Connect your iPhone with your Apple computer and open iTunes on macOS 10.14 (Mojave). If you’re running macOS 10.15 (Catalina) or later, launch Finder. The device can be switched on or off.
  • For iPhone 6s and later, press and hold the sleep and home buttons for eight seconds. If you have an iPhone 7 or later, hold down the sleep and volume down buttons for eight seconds.
  • Release the sleep button after eight seconds. Hold the home or volume down button down until the iPhone appears in iTunes or Finder.
  • Release the volume down or home button. If you’ve entered DFU Mode, the screen should be completely black. If it isn’t, go back to the start of this sequence.
  • Using the backup, restore your iPhone.

You don’t have to turn off your iPhone 8, 8 Plus, X, 11, or 12 to enter DFU Mode. Simply follow the instructions while the device is connected. If you see the Apple logo on the screen, it means you pressed the volume button for an extended period of time. You’ll have to retrace your steps from the beginning.

If you have physical damage to your iPhone, the DFU restore process may cause it to malfunction. It’s not worth trying this option if you’ve ever had your device checked for water or liquid damage.

If other components within the iPhone have already been damaged as a result of water exposure, the Device Firmware Update may not work as expected. With a DFU failure, a usable device with minor issues can become an expensive paperweight.

You could try a recovery or regular mode restore before the DFU to exhaust all possibilities before making a final decision about your muffled speakers. If the iPhone problems can be fixed with a restore, the Device Firmware Update has the best chance of success.

7. Repair Your Speaker

If your iPhone speaker continues to malfunction, it is time to have it professionally examined to determine the source of the problem. At this point, your problems are most likely caused by a hardware malfunction. You can make an appointment at your local Genius Bar to have your speaker evaluated.

It may take 24-48 hours to complete the work, particularly if you have a busy location. If you don’t have a Genius Bar near you, you can use Apple’s mail-in services if your AppleCare is current.

Most Apple devices come with a 90-day complimentary support window through AppleCare to ensure your product works correctly. They also have a limited warranty for you to use. In most countries, you can purchase an AppleCare extension within 60 days of your initial transaction.


A muffled iPhone speaker can be caused by either a software or a hardware issue. The software tells your iPhone when and what sounds to play. The noise is then played back by the hardware (the physical speakers).

We don’t know what kind of problem this is yet, so we’ll start with software troubleshooting. If those steps do not resolve your iPhone speaker issue, we will suggest a few excellent repair options!

1. Is Your Phone Set To Silent?

When you set your iPhone to silent, the speaker will not make any noise when you receive a notification. Check that the Ring / Silent switch above the volume controls is pushed towards the screen, indicating that your iPhone is set to Ring.

2. Turn up the volume to 110%

When you receive a phone call or notification and the volume on your iPhone is low, it may sound as if the speakers are muffled. To increase the volume on your iPhone, unlock it and press and hold the top volume button on the left side of the device until the volume is all the way up.

On your iPhone, you can also adjust the volume by going to Settings -> Sound & Haptics and dragging the slider under Ringer and Alerts.

Drag the slider all the way to the right to turn your iPhone’s volume all the way up. Turn on the switch next to Change with Buttons if you want to be able to increase the volume on your iPhone using the buttons.

3. Remove Your iPhone Case

If you have a bulky case for your iPhone, or if you put the case on upside down, the speaker may sound muffled. Take your iPhone out of its case and make a sound with it.

4. Clean Out Any Gunk From The Speaker

Lint, dirt, and other debris can quickly accumulate in your iPhone speakers, especially if it has been sitting in your pocket all day.

Wipe the speaker down with a microfiber cloth. To clean out more compacted gunk or debris, use an anti-static or an unused toothbrush.

5. Make a backup of your iPhone and put it in DFU mode

Before you rush to your nearest Apple Store for a hardware repair, let’s double-check that the speaker is indeed broken. A DFU restore is the final step you can take to rule out any software issues that are causing your iPhone speaker to sound muffled.

To begin, back up your iPhone. A DFU restore erases and then reloads all of your iPhone’s code. You’ll need a recent iPhone backup to avoid losing your contacts, photos, messages, and other data. You can use these guides to back up your iPhone using iTunes or iCloud.

After you’ve backed up your iPhone, follow these steps to put it in DFU mode. Before testing your speakers, repeat steps 1-4 and then try to play music or use your speakerphone. If the speaker continues to sound muffled, it’s time to investigate repair options.

6. Repairing Your iPhone Speaker

Apple offers repairs for iPhone speakers. You can schedule an appointment at the Genius Bar or use their mail-in service by visiting their support center. Puls is one of our favorite and often less expensive repair options.

They will send an iPhone repair expert to your chosen location and can have your iPhone repaired in as little as an hour. They also provide a lifetime warranty, so this may be the best choice for you!

If you have an older iPhone, you may want to consider upgrading to a new one rather than paying to repair it. New iPhones have improved stereo speakers that are ideal for listening to music or watching videos on the go. To find a great deal on a new iPhone, use UpPhone’s comparison tool!


You can purchase an AppleCare plan from your iPhone settings menu.

  • On your iPhone, open the Settings menu.
  • Go to General, then look for the About section.
  • Tap on AppleCare Plus Coverage Available. If you don’t see this option, your device is likely ineligible.
  • Follow the on-screen instructions to complete the purchase. You’ll be given the price of this protective policy when you follow these steps.

CONCLUSION on iPhone Speaker Sounds Muffled

When my iPhone speaker starts acting up, the first thing I check is whether the audio holes are clogged with debris. Because I keep the device in my pocket for the majority of the day, it eventually accumulates enough lint that the sound quality suffers.

In that situation, I like to use compressed air because it quickly removes the offending items without making a mess. Because the stuff can blow around the house if it’s really full, it’s best to do the work outside.

FAQs About iPhone Speakers

How can you tell if your iPhone speaker is blown?

Make sure the switch next to Change with Buttons is turned on (it will be green if it is). If you turn the volume all the way up and hear very, very quiet sound, your speaker is damaged.

Why is the sound on my iPhone distorted?

Check your sound settings and install the most recent iOS updates if your iPhone speaker sounds distorted. Then, using a soft cloth, electrical tape, or a soft-bristled brush, clean the speaker. If the problem persists, schedule a Genius Bar appointment to determine whether it is a hardware issue.

Why does my phone speaker sound fuzzy?

Your Android speaker net will accumulate dirt over time as a result of constant use. As a result, the phone’s ability to play sound is hampered, resulting in distorted audio. You can clean the speaker net by blowing air into it or using compressed air.
