Wired earphones have failure modes phone speakers do not — and one safety rule that matters more here than anywhere else on this site.
For a complete overview, see handling wet portable speakers.
The safety rule first
Never run cleaning tones through earphones while wearing them. The driver sits
millimetres from your eardrum and is a fraction of the size of a phone speaker. Volume appropriate for
a handset is not appropriate here. Remove them, set them mesh-down on a cloth, and use roughly half
the volume you would use on a phone.
Earwax is the usual cause, not water
The common blockage in any in-ear device is cerumen packed into the speaker mesh. It does not
respond to sound, because it is adhesive rather than loose. What removes it is careful dry cleaning:
adhesive putty pressed gently onto the mesh and lifted straight off, or a soft dry brush. Never liquid,
never anything sharp — that mesh is very thin and once punctured the driver is unprotected.
Cable faults, which speakers do not have
Wired earphones fail at flex points, and the symptoms are distinctive:
- Audio cuts in and out when you move the cable — a broken conductor inside the
insulation, usually at the plug or where the cable splits.
- One side silent — could be a cable break or a dead driver. Test by gently
flexing near the plug while audio plays; if it crackles or returns, it is the cable.
- Both sides quiet but present — more likely a blockage or a source volume
limit.
Cable faults are not repairable at home in any durable way, and no cleaning addresses them.
The plug and the socket
Lint compacts in a headphone socket exactly as it does in a charging port, and it prevents the plug
seating fully — which produces intermittent or single-channel audio. With the phone powered off, a
wooden or plastic toothpick scraped gently along the back wall usually retrieves a surprising plug of
lint. Never metal.
Rule out the source
Try the earphones on a different device before concluding they are faulty. A volume limiter, an
equaliser, or a stuck audio route on the phone produces symptoms identical to failing earphones, and
costs nothing to eliminate.
When cleaning is worth it
If both sides are equally muffled and the cable behaves normally when flexed, blockage is likely
and putty is worth trying. If one side is silent or the fault changes with cable movement, it is
electrical and cleaning will not help.
