How to clean earbuds without damaging the sound

Most people think earbuds get quieter because the battery is ageing or the speaker is wearing out. Far more often the sound is simply blocked. Every earbud has a fine mesh over the opening where sound leaves, and ear wax and skin oil build up on it a little each day. Sound has to pass through that mesh to reach your ear, so a coated mesh muffles it. Cleaning it properly, and keeping it dry, usually brings the volume back.

Why a blocked mesh makes earbuds quieter

The speaker inside an earbud is tiny and moves very little air. Its sound leaves through a small nozzle covered by a mesh that keeps dirt out. Ear wax is soft and sticky, so it fills the holes in that mesh gradually. The sound turns muffled first, and then everything gets quieter. If one earbud sounds weaker than the other, look at its nozzle in good light. A dull yellow or brown film on the mesh usually explains the difference straight away.

Take the silicone tips off first

The soft tips hold much of the wax and also hide the nozzle, so they have to come off. Grip each tip at its base and pull it straight off, with a slight twist if it is tight. Do not tug at the thin outer edge, because it tears easily. Wipe each tip inside and out with a dry, lint-free cloth. Pay attention to the inner tube, where wax collects unseen. Set the tips aside on a clean surface while you work on the earbuds themselves.

Dry brushing the mesh

With the tips off, hold the earbud with the nozzle facing down, so loosened wax falls out rather than further in. Use a soft, dry brush, such as a clean small paintbrush or a soft toothbrush kept only for this job, and brush across the mesh in short strokes. Gravity does part of the work. A dry cotton swab can then lift the film around the rim. Go gently. The mesh is thin, and pressing hard can dent it or push it loose.

Never push wax in, never use water

A pin, toothpick or firm swab pressed into the mesh tends to force wax deeper, past the mesh and onto the speaker itself, where you cannot reach it. Metal can also pierce the mesh. Water and other liquids are a worse idea. Many earbuds resist sweat, but liquid pushed into the nozzle can reach the speaker and the circuit behind it, and softened wax spreads rather than lifting off. Keep every step dry. If wax stays stuck, a technician can clean it safely.

The charging contacts and the case

The case charges each earbud through small metal contacts, on the earbud and in the cradle. Wax, skin oil and lint on those contacts stop current flowing, so one earbud may show as uncharged even though it sat in the case all night. Unplug the case from its charger before you start. Wipe the contacts with a dry cotton swab and brush out the cradle with a dry brush. Leave the case open for a while before you charge it again.

• Muffled or quiet sound: dry brush the mesh with the nozzle pointing down.
• One earbud not charging: wipe the metal contacts on it and in the case.
• Itching or soreness in the ear: clean the tips and stop sharing them for now.

What to try, in order

1. Unplug the charging case and lay the earbuds on a clean, dry cloth before you start any cleaning.
2. Pull off the silicone tips at their base and wipe them inside and out with a dry cloth.
3. Hold each earbud with the nozzle facing down and brush the mesh gently with a soft, dry brush.
4. Lift any remaining film around the nozzle rim with a dry cotton swab, without pressing into the mesh.
5. Wipe the metal charging contacts on each earbud and inside the case with a dry cotton swab.
6. Refit the tips, and clean them again after workouts or whenever they start to look shiny.
7. If the sound stays muffled after dry cleaning, take the earbuds to a service centre or technician.

What to take from this

Earbuds that sound quieter are usually blocked, not broken. Take the tips off, brush the mesh dry with the nozzle pointing down, and wipe the charging contacts while you are there. Skip pins, firm pressure and anything wet, because those turn a free fix into a repair. Clean tips also matter for your ears, since wax and skin oil hold bacteria. A few minutes of dry cleaning, done regularly, keeps both the sound and your ears in better shape.

Common questions

Why do my earbuds sound muffled?

Muffled sound almost always comes from ear wax and skin oil coating the mesh over the nozzle, which blocks sound on its way out. Remove the tip, look at the mesh in good light and brush it dry with the nozzle facing down. If one earbud sounds worse than the other, that earbud is usually the blocked one.

How often should I clean my earbuds?

There is no fixed rule, because it depends on how much you wear them and how much wax your ears make. A good habit is to look at the tips and mesh whenever you put them away. Clean them when you see a film or shine, and always after sweaty workouts, before the oil has time to harden.

Is it safe to share earbuds with someone else?

Sharing earbuds moves wax, skin oil and bacteria from one ear to another, which can cause irritation or an infection in some people. If you must share, wipe the tips with a dry cloth first, or better, fit a spare set of tips. Stop using them and clean everything if your ear itches or feels sore.
