How to Improve Audio Quality of iPhone 7 Calls

Before diving into the steps, let’s talk about what we’re aiming to achieve here. By following these instructions, your iPhone 7 will deliver clearer audio during calls, minimize background noise, and provide an overall better call experience.

Step 1: Update iOS

Ensure your iPhone 7 is running the latest version of iOS.

Updating your iPhone 7’s iOS can resolve underlying software issues that may be affecting call quality. To do this, go to Settings > General > Software Update and install any available updates.

Step 2: Clean Your Speakers and Microphone

Remove any debris from the speakers and microphone.

Dirt or debris lodged in your iPhone’s speakers or microphone can significantly reduce audio quality. Gently clean these areas with a soft brush or cloth to avoid damage.

Step 3: Disable Noise Cancellation

Turn off the phone noise cancellation feature.

Noise cancellation can sometimes interfere with call quality. You can disable this feature by going to Settings > Accessibility > Audio/Visual and toggling off Phone Noise Cancellation.

Step 4: Adjust Call Volume

Increase the call volume during a call using the volume buttons.

Sometimes the solution is as simple as turning up the volume. While on a call, press the volume up button to ensure the call volume is at its maximum.

Step 5: Use a Headset or Bluetooth Device

Consider using a headset or Bluetooth device for calls.

Connecting a high-quality headset or Bluetooth device can drastically improve call audio. It also allows for a more consistent placement of the microphone for better sound capture.


Enhanced ClarityUpdating iOS and cleaning your device can lead to clearer and more consistent audio during calls.
Reduced Background NoiseDisabling noise cancellation might seem counterintuitive, but it can sometimes improve the call quality by not over-filtering the sound.
ConvenienceUsing a headset or Bluetooth device not only improves audio quality but also frees up your hands, making multitasking during calls easier.


Possible Data LossUpdating iOS carries a slight risk of data loss if not backed up properly. Always ensure you have a recent backup before proceeding with an update.
Potential for DamageCleaning the speakers and microphone must be done carefully to avoid any damage to these delicate components.
Additional CostPurchasing a high-quality headset or Bluetooth device can be an extra expense if you don’t already own one.

Additional Information

While the steps above are straightforward, there are a few extra tips worth mentioning. First, consider the environment you’re in during calls. If you’re in a noisy area, even the best audio improvements may not fully overcome the background chatter. Finding a quiet space can make a significant difference.

Also, if you’re using a protective case on your iPhone 7, ensure that it’s not covering the speakers or microphone. Some cases can muffle the sound, so it’s worth checking if this might be an issue.

Lastly, remember that sometimes poor call quality can be due to network issues and not necessarily your device. If you’ve followed all the steps and are still experiencing problems, it might be worth contacting your service provider to check for any network-related issues.
