Call speaker · earpiece · receiver
Calls sound muffled. Everything else is fine.
That's almost always the earpiece speaker, not the main one. It's smaller, it's easy to miss when you're drying a wet phone, and it responds to the same sound-cycle fix.
- Separate driver from your main loudspeaker
- Same physics, smaller grille
- <1min to run a cycle
Hold the earpiece — the small opening near the top of your phone — face-down over a cloth, volume at maximum.
Quick answer
If calls sound muffled but music is fine, your earpiece (the upper speaker) is blocked. Hold the phone with the top edge facing down over a cloth, set media volume to maximum, and run Water Ejector if it got wet or Dust Buster for dust, face oil and makeup. The ear speaker cleaner sound takes 30–45 seconds; repeat once or twice, then test with a voice memo. If the other person can't hear you, it's your microphone instead — use the mic cleaner.
| Symptom on calls | Part | Fix |
|---|---|---|
| You can't hear them clearly | Earpiece / upper speaker | This page — top edge down |
| They can't hear you | Microphone | Mic cleaner & mic test |
| Speakerphone and music muffled too | Bottom loudspeaker | Main speaker cleaner |
| Crackling, dropouts on every call | Network or damaged earpiece | Test on Wi-Fi calling, then speaker test |
Finding the earpiece speaker
It's the narrow slit above your screen, not the grille on the bottom edge. On most phones it's easy to overlook because it's small and rarely gets attention during a general clean.
-
1
Locate the earpiece
The thin slit just above the display, used only during calls and voice memos.
-
2
Face it down, volume up
Rest the top edge of the phone on a soft cloth, media volume at maximum.
-
3
Run the cycle
Water Ejector or Dust Buster — the same tone that clears the main speaker also clears this one.
-
4
Test with a call
Play a voice memo or take a short call to confirm it's clear. Repeat once if it's still muffled.
Two speakers, two problems
A phone with a perfectly clear main speaker can still have a muffled earpiece, and vice versa — they're separate drivers behind separate grilles. If it's the bottom speaker that's affected instead, the main speaker cleaner is the right tool.
If calls sound bad on their end, not yours
A blocked earpiece only affects what you hear. If the other person says you sound muffled or distant, the problem is your microphone, not your earpiece — see the mic cleaner & tester instead.
What is the upper speaker, and why does it clog?
The earpiece — also called the call speaker, ear speaker, receiver or upper speaker — is the narrow slot above the screen. It's much smaller than the bottom loudspeaker and sits right where your cheek, ear and hair touch the phone on every call. That's why it clogs with a mix most people don't expect: face oil, makeup, sunscreen and earwax held together with pocket dust, rather than plain dust or water.
On many phones the earpiece also works as the second stereo speaker for music and videos. If one side of your stereo sound is weaker than the other, the top speaker is usually the one that's blocked — confirm it with the left/right speaker test.
Water vs dust in the ear speaker
Water in the earpiece makes voices sound distant, bubbly or crackly immediately after the phone gets wet. Dust and grease build up gradually and make voices dull and quiet. Water responds to the 165 Hz Water Ejector; oily build-up needs the Dust Buster sweep followed by a gentle wipe — see oil and makeup in the phone speaker.
How to clean the earpiece speaker safely
- Check the case and screen protector — a protector that overlaps the earpiece slot is a common hidden cause of quiet calls.
- Run the ear speaker cleaner sound: top edge facing down, volume at maximum, Water Ejector or Dust Buster.
- Brush the slot lightly with a clean, dry, soft toothbrush, sweeping outward.
- Lift grease with a small piece of low-tack tape or cleaning putty pressed on and peeled off. For oily residue, a toothbrush that's barely damp with isopropyl alcohol on the outside surface only, phone switched off.
- Test by playing a voice memo with the phone held to your ear, or make a short call.
Never push a pin, needle or toothpick into the earpiece mesh — it's thin and tears easily. More in how to clean a speaker grille without damage.

Call speaker questions
Why does my call speaker sound muffled but music plays fine?
Your phone has two separate speakers: the main bottom-firing loudspeaker for media, and the small earpiece near the top for calls. They have separate grilles, so one can collect dust or moisture while the other stays clear.
How do I clean my earpiece speaker?
Hold the earpiece facing down over a soft cloth, volume at maximum, and run Water Ejector or Dust Buster from this page. The grille is smaller than the main speaker but responds to the same principle.
Will this fix a scratchy or crackling call speaker?
It helps when the crackle comes from debris or moisture against the diaphragm. If it persists after two or three cycles, the driver itself may need a hardware repair.
Does the other person hear better once I clean it?
Cleaning the earpiece improves what you hear, since that's the speaker pointed at your ear. If the other person can't hear you, that's your microphone — see the mic cleaner for that.
How do I fix my upper speaker?
The upper speaker is the earpiece. Hold the phone top edge down, run the Water Ejector or Dust Buster cycle on this page at full volume, brush the slot gently, then test with a voice memo held to your ear.
What is an ear speaker dust cleaning sound?
It's a high-frequency sweep that vibrates the earpiece mesh to loosen dust. Dust Buster on this page sweeps 3,000–9,000 Hz for 30 seconds, which works well for the earpiece's small opening.
Is "clear speaker" the same as a call speaker cleaner?
"Clear speaker" usually means any tone that clears a muffled speaker. This page applies it to the earpiece; the main speaker cleaner is for the bottom loudspeaker.
How do I test my call speaker?
Play a voice memo or video with the phone held to your ear, or make a short call. The speaker test also shows whether the earpiece works as the second stereo channel.
Muffled call speaker, right now?
Skip back up, pick Water Ejector, and give it 45 seconds.
