If your headphones cut out, crackle, only work when the plug is held at an angle, or your phone thinks headphones are plugged in when they aren't, the fault is the headphone jack or audio port . Repair Mate® repairs 3.5mm jacks and USB-C/Lightning audio faults on phones and tablets — usually the same day. 3.5mm jack, or USB-C / Lightning audio? How your device plays wired audio depends on its age and model — and the fix differs: 3.5mm headphone jack — the classic round socket, still common on many tablets, older phones and budget models. It's a replaceable part when it wears out. USB-C or Lightning audio — most modern phones dropped the 3.5mm jack, so wired audio runs through the charging port (directly or via an adapter). Here, an “audio” fault is often really a charging-port fault. Because modern phones share the charging port for audio, “my headphones don't work” and “my phone won't charge” can be the same underlying port problem . We diagnose the one port that does both. Signs your audio port needs repair No sound in headphones , or sound only in one ear. Crackling or cutting out unless you hold or wiggle the plug. The plug feels loose or doesn't click/seat properly. Stuck in “headphone mode” — the speaker stays silent because the phone thinks headphones are still plugged in. Wired headphones aren't detected at all. What causes it — and the cheap fix first The single most common cause is lint and pocket dust compacted inside the port , which stops the plug seating and can trick the phone into “headphone mode.” Other causes are moisture/corrosion , a bent or worn socket from years of use, and drop damage . Our first step is always a careful clean and inspection — surprisingly often that alone restores sound, at no cost of a new part. If the socket itself is worn or corroded, we quote a replacement. Prevent audio-port problems Keep the port clean — lint is the number-one cause; blow it out gently, never jam metal in. Insert plugs straight , and don't yank the cable out at an angle. Keep moisture out — dry the device before plugging anything in. Consider Bluetooth for daily use to spare a worn socket.

Frequently asked questions My speaker went silent and the phone says headphones are connected — but nothing is plugged in. Why? That's the classic “stuck in headphone mode” fault — usually lint or moisture in the port fooling the sensor. A clean often fixes it; if not, the port needs repair. My phone has no headphone jack — can you still fix my wired audio? Yes. On modern phones wired audio runs through the USB-C or Lightning charging port, so we repair that port — which usually restores both charging and audio. Sound only works if I hold the plug at an angle — what's that? The socket contacts are worn or dirty. We start with a clean; if the socket itself is worn out we replace it and test both channels. Could it just be my headphones, not the phone? Easily — so we test with known-good headphones and, on 3.5mm devices, check the socket directly. You won't pay for a port repair if the cable was the problem. How long does it take? A clean is often done on the spot; a jack or port replacement is usually same-day in-store, or quickly turned around by express post for mail-in. Will the repair erase my data? No — audio-port work doesn't touch your storage. Your data stays intact. Related repair guides Not the repair you were after?
