Take the ear tips off and look at the mesh
Apple's own check for AirPods that sound quiet is to remove the ear tips and inspect the microphone and speaker mesh on each AirPod for debris. That is where earwax and lint collect, and a partially blocked mesh dulls the treble long before it silences anything — which is exactly what muffled means. If both meshes are visibly clean, the cause is elsewhere: an ear tip that is not sealing, a call rather than music, or a comparison you are making against the wrong thing.
Applies to: AirPods 1–4, AirPods Pro 1–3 and AirPods Max. Cleaning procedures differ between AirPods and AirPods Pro and Apple publishes separate articles for each; the ear tip and seal guidance applies to AirPods Pro and the in-ear models.
When does it sound wrong?
Muffled is a description of treble loss, and treble is the first thing a physical obstruction removes. That makes cleaning the highest-yield step by a wide margin. But two other causes produce the identical impression without any dirt involved — a poor ear tip seal, which loses bass and makes everything sound thin and distant, and Bluetooth's lower-quality call mode, which affects every wireless earbud ever made. Work through them in that order.

Compare sides1. Debris in the mesh, and Apple’s cleaning method
Apple's diagnostic for AirPods that are too quiet is to remove the ear tips and check the microphone and speaker mesh on each AirPod, cleaning them if there is any debris. Do this in good light and compare the two earbuds against each other — a mesh that looks slightly grey or matted next to its twin is blocked, even if neither looks dramatically dirty.
The cleaning method Apple documents is worth following exactly. Hold the AirPod with the mesh facing up so gravity works with you rather than pushing debris inward, and brush the mesh in circles for about 15 seconds with a soft-bristled brush. For stubborn build-up, put a small amount of micellar water in a cup and dip the brush until the bristles are fully saturated — the liquid goes onto the brush, never onto or into the AirPod.
Then wait. Apple's instruction is to let the AirPods dry completely, for at least two hours, before putting them in the charging case or using them. That is not caution for its own sake: putting a damp AirPod into the case is how a cleaning session turns into a charging fault. Never use compressed air, and never poke anything sharp through the mesh — the mesh is there to protect the driver behind it.
Earwax is the usual culprit and it accumulates gradually, so the sound degrades slowly enough that you adapt to it. People are routinely surprised by how much better a cleaned AirPod sounds, having not noticed it getting worse.
2. The ear tip seal, which changes everything
Apple states the requirement plainly: the ear tips should make a good seal with your ear canal for the best sound quality and noise cancellation. A seal that has broken produces a very specific impression — thin, distant, bass-light audio, and noise cancellation that seems to have stopped working. People describe it as muffled even though it is technically the opposite, because the overall effect is of sound arriving from further away.
Try the other tip sizes rather than assuming the fitted ones are right. Ears are not symmetrical and a different size on each side is common and correct. AirPods Pro include an Ear Tip Fit Test in the AirPods settings that plays audio and measures the seal, which takes seconds and gives a definite answer rather than a guess.
Then check the tips themselves. Apple's guidance is to pull the ear tips off each AirPod, rinse them with water — no soap or household cleaners — and wipe them with a soft, dry, lint-free cloth. Make sure they are completely dry before refitting. Tips also perish: silicone hardens and loses grip with age, and a hardened tip cannot seal however carefully you insert it.

AirPods Pro have an Ear Tip Fit Test in the AirPods settings that measures the seal directly.
Cleaning tips
Pull them off, rinse with water only, wipe with a dry lint-free cloth, and refit only when fully dry.
3. If only calls sound bad
This is the cause that no amount of cleaning will touch, and it is not a fault. Whenever the microphone is active, Bluetooth switches from a one-way high-quality audio path to a two-way mode that carries far less information in both directions. Your music sounds full; the moment a call connects, everything drops in quality — including what you hear.
The tell is precise: audio quality changes at the exact moment a call starts and recovers the instant it ends. If that is your pattern, the earbuds are working correctly and every wireless earbud on the market behaves the same way. It is the single most common reason people conclude their AirPods have degraded when nothing has changed.
There is one thing worth checking alongside it. Some applications on computers open the microphone even when you are only listening — conferencing tools left running in the background, or a browser tab holding microphone access. That forces the low-quality mode permanently, so music sounds muffled all the time for a reason that has nothing to do with music. Quit those apps properly and the quality returns.
This applies to any wireless earbuds, not just AirPods. If someone tells you a different brand fixes it, they are describing a different codec rather than an escape from the two-way mode.
4. When one side sounds worse
A difference between the two earbuds is genuinely useful information, because it rules out everything that affects both equally — the source, the codec, the call mode. Swap which ear each AirPod is in. If the dullness moves with the earbud, that earbud is blocked or failing; if it stays in the same ear, the difference is your ear or that tip's seal rather than the hardware.
Check the audio balance setting before concluding anything, because a balance slider nudged off centre produces exactly this and is easy to change accidentally. It lives in the device's accessibility audio settings, and it is worth confirming it is centred whenever one side sounds quieter rather than duller.
One AirPod that has become dramatically worse than the other, with a clean mesh and a good seal, is a hardware difference rather than a cleaning problem — and a completely silent side is a different fault with its own diagnosis rather than a severe version of this one.
5. Settings and software that dull the sound
A few software causes imitate a hardware problem. On iPhone and iPad, an EQ preset applied in the Music settings affects all playback from that app and persists until changed — a preset that rolls off treble sounds exactly like a blocked mesh. Accessibility features that limit loud sounds or apply headphone accommodations do something similar, and both are easy to have enabled once and forgotten.
Streaming quality is the other common one. A music service set to a low bitrate on cellular data, or one that has dropped quality because of a weak connection, sounds dull in a way that has nothing to do with the earbuds. Test with a file stored on the device rather than streamed — the same test that separates a stream from a Bluetooth problem when audio cuts out.
Firmware is worth having current before you conclude anything, since audio processing is part of what firmware controls. It installs by itself when the AirPods are in the case, charging, and near an iPhone or iPad on Wi-Fi, so leaving them charging overnight next to the phone is the practical way to make it happen.
6. When it is the hardware, and what to tell support
The case for a hardware fault is specific: sound that is still dull after a proper clean and a full two-hour dry, with a confirmed tip seal, on stored audio rather than a stream, with EQ off, and worse on one side than the other consistently across ears. Water exposure and a hard drop are the two histories that make it likely, and neither improves with more cleaning.
Weigh age honestly. AirPods are consumable in a way people resist accepting — the batteries degrade, the meshes eventually clog past cleaning, and a pair several years into daily use is near the end of its service life rather than broken. If cleaning restores the sound for a week and then it dulls again, the wax is coming from your ears faster than the mesh can be maintained, which is normal and eventually terminal for that earbud.
When you contact Apple Support, describe the pattern rather than the word muffled. Say whether it affects calls only or everything, whether it is worse on one side and whether that follows the earbud when swapped, whether the meshes have been cleaned and dried for two hours, whether a stored file sounds the same as a streamed one, and whether the ear tip fit test passes. Those five answers separate a blocked mesh from a seal problem from call-mode audio from a failing driver.
Frequently asked questions
Why do my AirPods sound muffled?
Usually debris in the speaker mesh. Apple's check for quiet AirPods is to remove the ear tips and inspect the microphone and speaker mesh on each one — earwax and lint collect there and dull the treble long before they silence anything. Compare the two earbuds side by side in good light; a mesh that looks slightly greyer than its twin is blocked.
How do I clean the speaker mesh on AirPods?
Hold the AirPod with the mesh facing up and brush it in circles for about 15 seconds with a soft-bristled brush. For stubborn build-up, dip the brush in a little micellar water until the bristles are saturated — the liquid goes on the brush, never on the AirPod. Then let them dry completely for at least two hours before putting them in the case.
Why do my AirPods sound fine for music but bad on calls?
Because Bluetooth switches to a lower-quality two-way mode whenever the microphone is active, and that affects what you hear as well as what they hear. Quality drops the moment a call connects and recovers when it ends. Every wireless earbud does this — it's the protocol, not a fault, which is why cleaning changes nothing.
Why do my AirPods Pro sound thin with no bass?
That's a seal problem rather than a blockage. Apple notes the ear tips need to make a good seal with your ear canal for the best sound quality and noise cancellation, and a broken seal loses bass and makes everything sound distant. Try other tip sizes — a different size in each ear is common — and run the Ear Tip Fit Test in the AirPods settings.
Can I wash AirPods ear tips?
Yes, with water only. Apple's guidance is to pull the tips off each AirPod, rinse them with water — no soap or other household cleaners — and wipe them with a soft, dry, lint-free cloth. Make sure they're completely dry before refitting. Note that silicone tips harden with age and a hardened tip can't seal no matter how well you fit it.
My music sounds muffled all the time, not just on calls. Why?
Check whether something is holding the microphone open. A conferencing app left running in the background, or a browser tab with microphone access, forces the low-quality two-way Bluetooth mode permanently — so music sounds muffled for a reason unrelated to music. Quit those apps properly. Also check for an EQ preset in your music app and any accessibility audio settings.
