What to Do If Call Volume Is Very Low on Bluetooth Earbuds After iOS 27 Update

Call Volume Is Very Low on: what you need to know

Why Is Call Volume Low on Bluetooth Earbuds After Updating to iOS 27?

After updating to iOS 27, many users have reported experiencing significantly reduced call volume when using Bluetooth earbuds. This issue can be frustrating, especially when you rely on your earbuds for clear phone conversations. Several factors may contribute to this problem, including changes in how iOS manages audio routing, potential Bluetooth compatibility glitches introduced by the update, or audio settings that may have been reset during the installation process.

iOS updates often bring improvements and new features, but they can also introduce changes in system behavior that affect peripheral devices like Bluetooth earbuds. For example, the update might alter the way audio profiles are handled or adjust default volume levels for calls versus media playback. These subtle changes can result in noticeably lower call volume or degraded audio quality during phone calls.

Understanding the root causes can help you troubleshoot effectively. It’s important to differentiate between issues caused by software changes and those related to hardware or Bluetooth connection stability. Sometimes, the earbuds themselves may need firmware updates to maintain compatibility with the latest iOS version.

How to Fix Low Call Volume on Bluetooth Earbuds After iOS 27 Update

If you’re experiencing low call volume on your Bluetooth earbuds after updating to iOS 27, try the following troubleshooting steps. These methods address common causes and can help restore your call audio to a comfortable level.

1. Adjust Call Volume During the Call
   One of the simplest solutions is to manually increase the call volume while you are on a call. Use the physical volume buttons on the side of your iPhone to raise the call volume. Keep in mind that call volume is often controlled separately from media volume, so adjusting the volume outside of a call may not affect call audio levels. Make sure to test this during an active call to ensure the volume is set correctly.
2. Reconnect Your Bluetooth Earbuds
   Bluetooth connections can sometimes become unstable or misconfigured after an iOS update. To address this, turn off Bluetooth on your iPhone, wait a few seconds, and then turn it back on. Next, go to Settings > Bluetooth, find your earbuds in the list of paired devices, and choose to "Forget This Device." After that, pair your earbuds again as if they were new. This process refreshes the Bluetooth connection and can resolve audio profile or routing issues that might be causing low call volume.
3. Check Bluetooth Audio Settings
   iOS includes several accessibility features that affect audio output. Navigate to Settings > Accessibility > Audio/Visual and verify that "Phone Noise Cancellation" is enabled. This feature helps reduce ambient noise during calls, which can improve clarity and perceived volume. Also, check if "Mono Audio" is turned off unless you specifically need it. Mono Audio combines stereo channels into one, which can sometimes reduce audio quality and volume on one side of your earbuds.
4. Restart Your iPhone
   Restarting your device is a simple but effective troubleshooting step. It clears temporary system glitches and refreshes hardware connections, including Bluetooth. To restart, press and hold the power button and either volume button until the slider appears, then slide to power off. After the device shuts down, press the power button again to turn it back on. Once restarted, test your earbuds during a call to see if the volume has improved.
5. Update Earbuds Firmware
   Many Bluetooth earbuds come with companion apps that allow you to check for and install firmware updates. These updates often include bug fixes and improvements to compatibility with the latest operating systems. Open the app associated with your earbuds and look for a firmware update option. Keeping your earbuds’ firmware current can resolve issues like low call volume and improve overall audio performance.
6. Reset Network Settings
   If the problem persists despite trying the above steps, resetting your network settings can help. This action clears all saved Wi-Fi networks, Bluetooth pairings, and VPN settings, effectively giving your iPhone a fresh start with network connections. To do this, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. After the reset, you will need to reconnect to Wi-Fi networks and pair your Bluetooth devices again. This step often resolves stubborn Bluetooth audio issues caused by corrupted settings.

If the Problem Continues

If none of the above solutions improve the call volume on your Bluetooth earbuds, further investigation may be necessary. First, test your earbuds with another device, such as a different smartphone or tablet, to determine if the issue is with the earbuds themselves. If the volume is normal on other devices, the problem likely lies with your iPhone or its iOS 27 update.

Alternatively, try using a different pair of Bluetooth earbuds or headphones with your iPhone. If the new device works fine, this confirms the issue is specific to your original earbuds’ compatibility with iOS 27.

In cases where the problem only occurs on your iPhone after updating to iOS 27, and you have ruled out hardware faults, it may be necessary to contact Apple Support. They can provide guidance on known software bugs or offer repair options if a hardware defect is suspected. Visiting an Apple Store for hands-on diagnostics is also a good option if you prefer in-person assistance.
