How to Fix iPhone 6 Plus Sound Too Low or No Sound During Calls

by

If the sound on your iPhone 6 Plus is way too low—or if people can’t hear you unless you’re on speaker—you’re not alone. These audio issues are pretty common, and luckily, there are a few things you can try before heading to a repair shop. Here’s how to troubleshoot both problems step-by-step.

iPhone 6 Plus Sound Level Too Low During Calls

The Issue:
The earpiece speaker (the one you hold to your ear) sounds very faint even when your volume is maxed out.

How to Fix It:

1. Remove Any Case or Screen Protector

  • Some cases or screen protectors can partially block the earpiece, muffling the sound.
  • Remove them and test a call without any accessories on the phone.

2. Clean the Earpiece Speaker

  • Check if dirt, dust, or debris is covering the speaker.
  • Use a soft-bristled brush or compressed air to gently clean the speaker area.

3. Turn On Hearing Aid Mode
This boosts the volume and clarity for calls.

  • Go to Settings > Accessibility > Hearing Devices.
  • Turn on Hearing Aid Compatibility.

4. Restart Your iPhone

  • Press and hold the Power button.
  • Slide to power off, then turn your phone back on after a few seconds.

5. Still Low? It Might Be a Hardware Issue
If none of the above fixes it, the earpiece speaker might be faulty. At that point, it’s best to have your iPhone checked at an Apple Store or an authorized service center.

iPhone 6 Plus Callers Can’t Hear You Unless on Speaker

The Issue:
You can hear people fine, but they can’t hear you—unless you switch to speakerphone.

How to Fix It:

1. Check the Headphone Jack

  • Make sure there’s nothing plugged into the headphone jack.
  • If you see a headphone icon stuck on the screen without anything plugged in, your iPhone might think headphones are still connected.
    • Try inserting and removing a pair of headphones several times.
    • Restart the phone and check again.

2. Clean the Headphone Jack

  • Dirt or moisture in the jack could confuse the phone.
  • Use a can of compressed air to clean out the port carefully.

3. Turn Off Bluetooth
If your phone is still paired with a Bluetooth headset or speaker, audio might be routed there instead.

  • Go to Settings > Bluetooth and switch it off.

4. Reset Your iPhone (Optional Step)
If none of the above worked:

  • Back up your iPhone via iCloud or a computer.
  • Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.
  • Set it up as a new device and test the microphone before restoring your backup.

5. Still Not Working?
If callers still can’t hear you after all this, the problem could be with the microphone hardware. You’ll need to have your device looked at by a technician.

  1. I used toothbrush, and it works like wonders. I was just going to service center even though my warranty is gone as it was a major problem of low hearing from rhe reciever box.

    But after brushing it off with toohtbrush the dust instantly came out and when I called someone, it was like 80 times louder. Thanks for the suggestion mate. 🙂

  2. I took a thumb tact and punctured a small hole in the very top right of the speaker where you place your ear and now I can suddenly hear perfect—- I mean like 100 times louder
