How to Remove a Broken Headphone Jack (3.5mm)

Introduction: It happens in a split second. You pull your headphones, but only half the cable comes out. The metal pin (the 3.5mm tip) is snapped off and stuck deep inside the audio jack of your phone, tablet, or laptop.

Panic sets in. You might be tempted to grab super glue or a drill. STOP!

Using glue is the fastest way to permanently ruin your device’s audio port. At LifeKaki, we specialize in smart, safe DIY repairs. Today, I will show you how to extract a broken audio plug using simple physics and a common household item-without taking your device apart.

Why “The Pen Refill Method” Works Best

Many online guides suggest using super glue on the end of a stick. This is dangerous because one drop of glue on the sidewalls of the socket will disable the port forever.

Our method relies on mechanical friction and interference fit. By finding a tube with the perfect diameter, we can slide it over the broken pin, creating a tight grip that allows us to pull the obstruction out safely.

Tools You Need

Broken 3.5mm plug (stuck inside the device).
Plastic ink tubes from ballpoint pens (gather 3-4 different types/brands to find the right size).
A pair of pliers or strong scissors.
Patience.

Step-by-Step Guide: Extracting the Jack

Step 1: Prepare Your “Extraction Tool”

Disassemble a few ballpoint pens. You are looking for the inner tube that holds the ink. The goal is to find a tube where the inner diameter is slightly smaller than or exactly equal to the diameter of the broken metal pin stuck in your phone.

Tip: Cheap, generic pens often have softer plastic tubes, which work best for this trick.

Step 2: Clear the Tube

If the pen tube still has ink or a metal tip, cut it off. You need a hollow, clean plastic tube. Make sure the cut is straight, not angled.

Step 3: The “Push and Twist” Technique

Insert the empty plastic tube into the headphone jack.
Push it down firmly until you feel it touch the broken metal piece.
Apply steady pressure. You need the plastic tube to expand slightly and slide over the broken metal pin.
Once you feel it grip (it feels like a tight wedge), give it a slight twist to lock it in place.

Step 4: The Extraction

Take a deep breath. Pull the plastic tube out steadily and quickly. If the friction was sufficient, the broken headphone tip will come out stuck inside the plastic tube.

⚠️ Troubleshooting: What if it doesn’t work?

Scenario A: The tube is too loose. The tube enters easily but doesn’t grip the pin.

Fix: You need a tube with a smaller diameter or thicker walls. Try a different brand of pen.

Scenario B: The tube is too thick. The tube won’t fit into the hole alongside the pin.

Fix: You can gently heat the tip of the plastic tube with a lighter (for just 1 second) to soften it before inserting. Warning: Be extremely careful not to touch the hot plastic to the phone’s casing.
