iPhone X Speaker Not Working: Earpiece and Stereo Checks

An iPhone X that has lost sound is usually down to one half of its stereo pair: the earpiece and the bottom loudspeaker work together, so when one fails the sound goes lopsided or vanishes from calls and media. Testing each speaker on its own will show whether the fault is a setting, dirt, or hardware.

Test Each Speaker on Its Own Before Anything Else

The iPhone X plays stereo through two speakers at opposite ends that fail independently: the earpiece handles calls and the left channel, the bottom speaker the right channel and most of the volume. A fault in one can look like a fault in both until you separate them.

Start with a call, holding the phone to your ear: if the caller is silent or faint, the earpiece is struggling. Tap speakerphone mid-call — if the caller comes through loud and clear, the earpiece is faulty and the loudspeaker healthy. Now play a song and cover the bottom grille: if the music almost vanishes, the earpiece contributes little and the bottom speaker does nearly all the work.

Try the same song in landscape at arm’s length: a healthy pair sounds wide and even, while a dead earpiece makes everything collapse to the bottom end. Note which speaker failed each test.

Stereo Balance: Why One Side Sounds Louder

A common iPhone X complaint is lopsided sound, not silence: the bottom speaker loud while the earpiece is barely there. Some difference is built in — the bottom speaker is larger — but a big gap means something has shifted.

Open Settings, then Accessibility, then Audio/Visual, and centre the balance slider. Mono audio in the same menu is another culprit: with it on, the phone mixes both channels, making a weak speaker seem dead. Switch it off and listen to a stereo track in landscape.

Check for an app-level cause too: some apps have their own balance settings, and a still-connected Bluetooth device — a speaker, car stereo, earbuds in a case — can quietly steal the audio. Disconnect Bluetooth while testing and play the same track in two apps; if the imbalance follows the phone, the cause is in the phone.

The Earpiece Shares Its Home With the Face ID Sensors

This is what makes the iPhone X different: the earpiece shares its front assembly with the TrueDepth camera behind Face ID, so a knock, drop, or moisture there can affect both at once.

If your earpiece is quiet and Face ID has also become unreliable, the two problems are probably connected, and the front sensor assembly is the likely fault. Never open the phone yourself: the assembly is delicate, and disturbing it can disable Face ID permanently.

A repair shop will test the earpiece and Face ID together before quoting, because replacing the earpiece means working around the sensors. If Face ID works fine and only the earpiece is faulty, the repair is simpler and cheaper. Tell the technician about both symptoms so the whole assembly is diagnosed.

Water, Dust and the Bottom Speaker Grille

The bottom speaker is the most exposed part of the audio system: its grille faces downward into pockets and hands, collecting lint, dust, and moisture. A blocked grille muffles the loudspeaker and unbalances the stereo pair — and as the seals age, moisture can reach the speaker itself.

Look at the grille holes in good light: if they look grey or filled, brush them gently with a soft, dry toothbrush, stroking outward so debris falls away. Never poke a pin into the holes — you will puncture the membrane behind them. If the phone was recently splashed, let it dry fully in open air and avoid charging while wet.

You can also try the free speaker cleaner tool on the myspeakerfix.com homepage: it plays tones that shake water and dust loose, a useful first step after any splash. If the sound returns but fades again, moisture may be sitting inside — have a repair shop look before corrosion sets in.

Software Checks That Cost Nothing

Before spending money on a repair, spend ten minutes on the software checks: a hung audio process, a misbehaving app, or a setting changed by accident can all silence a speaker that is physically fine.

Restart the phone first, then check for a software update and install anything waiting — audio bugs are often fixed quietly in updates. Test the speakers in several apps: a problem in one app only belongs to that app. If sound is missing everywhere, open Control Centre and confirm the volume is up, Bluetooth is off, and the silent switch is not engaged.

As a deeper step, reset all settings (Settings, then General, then Transfer or Reset iPhone, then Reset All Settings). This clears audio and network preferences without deleting photos or apps, but back up first. If the speakers stay silent after a reset, the fault is almost certainly hardware.

When a Repair Is the Sensible Next Step

If you have tested each speaker, centred the balance, cleaned both grilles, and reset the settings, and one speaker is still silent or distorted, the hardware has failed — usually the earpiece module, the bottom loudspeaker, or the front sensor assembly. Each has a different repair cost, which is why these tests matter before you walk into a shop.

Take your test notes with you: which speaker failed, whether Face ID is acting up, and whether the problem started after a drop or a splash. A good technician will quote accurately from those details. Earpiece and loudspeaker replacements are routine, and a fresh speaker restores the stereo sound the phone was designed for.

Weigh the repair against the phone’s overall condition: if the battery is healthy and everything else works, replacing a speaker is far better value than replacing the handset. If the screen is cracked and the battery failing too, put the repair money toward a newer phone instead.
