Compare the microphone input, then compare each earbud
Hearing music through AirPods does not prove their microphone is selected. Check the input in your call app first. If the input is correct, use the AirPods Microphone setting to compare Always Left with Always Right in the same quiet-room test. One consistently bad side points toward that earbud; both sides working elsewhere points toward the original app or device.
Applies to: AirPods 1–4 and AirPods Pro 1–3, primarily with iPhone, iPad, and Mac. The left/right microphone selection and case reset instructions do not apply to AirPods Max. Third-party apps can have their own input and mute controls.
Who can hear you, and where?
A silent microphone and a muffled microphone need different checks. Start with a repeatable sample: the same sentence, the same app, and the same room. Change one setting at a time. The comparisons below help distinguish missing app access, the wrong audio input, an individual earbud problem, and a connection that needs rebuilding. They narrow the fault; they do not establish a hardware diagnosis on their own.
Music works, but callers hear nothing
Which microphone is the call actually using?
Check the inputOnly one app cannot hear you
Does it have microphone permission?
Check app accessYour voice cuts out when using one earbud
Is the microphone fixed to the other side?
Compare left and rightYour voice is muffled in every app
Does the same earbud fail in another device test?
Inspect and compare1. Confirm the call is using the AirPods microphone
On a Mac, open System Settings → Sound → Input and select your AirPods. Speak normally and watch the input-level meter. Then inspect the calling app’s microphone selector, if it has one, and its mute button. A meeting app may offer a different selection from the system setting. Selecting AirPods for sound output alone is not a microphone test.
Compare the AirPods input with the computer’s built-in microphone in that same app. If both fail, begin with app access in the next section. If only the AirPods fail, continue to the earbud comparison. On iPhone, check the call’s audio route and mute state, then compare a call using the phone itself. Avoid treating an arbitrary recording as proof unless you know which input the app recorded.
2. Separate an app permission problem from an accessory problem
On iPhone or iPad, check Settings → Privacy & Security → Microphone and enable access for the intended app. On Mac, the equivalent list is in System Settings → Privacy & Security → Microphone. Grant access only to the app you want to use. Reopen it and repeat the same sample after changing the setting.
If one app remains silent but another receives the AirPods clearly, record that difference. It is more useful to the app developer than a general report that Bluetooth is broken. For a browser call, check that site’s microphone permission and selected input as well as the browser’s system permission. Re-pairing the earbuds cannot substitute for access the app does not have.
3. Test the left and right microphones separately
With both AirPods worn and connected, open Settings on iPhone or iPad and tap their name. On Mac, select their name in System Settings. Under Microphone, choose Always Left AirPod, test, then choose Always Right AirPod and repeat. Apple also offers Automatically Switch AirPods. A fixed choice stays selected even when that earbud is removed or placed in its case.
Our suggested comparison is a short sentence spoken at your normal volume in a quiet room. Keep the app and device unchanged between samples. A repeatable difference makes the affected side worth investigating; one bad call over an unreliable network is weaker evidence. Restore Automatically Switch AirPods afterward, unless you deliberately need the working side as a temporary workaround.
If you use a fixed microphone as a workaround, keep that earbud available during calls. It does not repair the other earbud.
4. Inspect the affected earbud and repeat on another device
Look for visible contamination around the microphone meshes. Use Apple’s cleaning page for your exact generation: the AirPods and AirPods Pro pages illustrate different permitted areas. Do not insert a pin into an opening or improvise a liquid-cleaning method from another model. Let the earbuds dry for the full time required by the applicable instructions before testing or charging.
If possible, repeat the same left/right comparison on another compatible device. If the fault follows one earbud across both devices and multiple apps, the evidence points more strongly toward that earbud. If both sides sound clear elsewhere, return to the first device’s input settings and software. Keep the test indoors so wind and traffic do not obscure the result.
5. Check software, then reset only if the fault persists
Check Apple’s current firmware page against the version shown in your AirPods information. Updates arrive automatically while the AirPods charge near a paired iPhone, iPad, or Mac connected to Wi-Fi. Follow that page’s update procedure rather than looking for an unofficial firmware download. Retest before making another change.
For a reset, put the earbuds in the case, close it for 30 seconds, and forget them in the paired iPhone or iPad’s Bluetooth settings. Open the lid. On AirPods 1–3 and Pro 1–2, hold the rear setup button about 15 seconds until amber, then white. On AirPods 4 and Pro 3, double-tap the front while the light is on, again when it flashes white, and again when it flashes faster. Reconnect after amber, then white.
Resetting removes the pairing and requires setup again. Save the comparison results first so you can tell whether anything changed.
6. Give support the failing side and the comparison results
If the same microphone remains unusable after the supported cleaning and reset procedures, request an assessment through Apple’s AirPods support. Bring the model, firmware version, affected side, tested devices, and whether the built-in microphone worked in the same app. Mention any drop or liquid exposure without assuming it explains the fault.
A useful report reads: left input clear, right input muffled, reproduced in two apps on two devices. That gives support a concrete result to reproduce. If only one app fails, contact that app’s developer instead. Stop repeating resets once the evidence is stable; another identical reset adds little information.
Frequently asked questions
Why can I hear music but nobody can hear me?
Playback confirms the output works. Check the call’s input selection, mute state, and microphone permission before testing individual earbuds.
Can I use only the working AirPod microphone?
You can temporarily select Always Left or Always Right in the AirPods Microphone setting. Keep the selected earbud available; return to automatic switching when the problem is resolved.
Does a muffled microphone mean the AirPod is broken?
Not by itself. Compare sides in a quiet room, inspect the correct meshes, and repeat on another device. A persistent fault that follows one earbud is stronger evidence for a service assessment.
Should I reset AirPods when only one app fails?
Check that app’s permission and microphone selection first. Clear audio in another app makes an app-specific fault a more useful starting point.
