There are several ways to repair cracked plastic headphones. While glues and epoxies are an option, they often fail to hold the plastic together under tension. A more effective method is to use duct tape, electrical tape, or silicone tape to bind the cracked plastic. To reinforce the structure, some people suggest inserting a wire (such as a cut-up coat hanger) into the headband before taping it in place. For a more permanent solution, you can try drilling small holes on either side of the break, inserting a wire, and then sealing it with heat shrink tubing or tape.

What You'll Learn
Using duct tape
Duct tape is a popular solution for fixing broken headphones. It is a quick and easy fix that can be done at home with minimal tools. While it may not be the most elegant solution, it is functional and can save you from having to buy a new pair of headphones.
To fix cracked plastic headphones using duct tape, start by assessing the damage and ensuring that all the broken pieces are stable and not likely to cause injury. If there are any loose pieces of plastic, you can carefully remove them or tape them down to create a smooth surface. Clean the surface of the headphones with rubbing alcohol to remove any dirt or oil that may interfere with the adhesion of the tape.
Next, cut a piece of duct tape that is slightly longer than the cracked area. You may need to experiment with the length and width of the tape to ensure full coverage of the crack without any excess. Carefully apply the tape over the crack, smoothing it down as you go to avoid air bubbles. Make sure the tape is securely adhered to the headphones, especially at the edges, to prevent peeling.
Depending on the location of the crack, you may need to cut the duct tape into smaller pieces to fit around curves or tight spaces. Work slowly and carefully to ensure that all areas are covered and secured. If needed, you can layer multiple pieces of tape to create a stronger bond.
Finally, test the headphones to ensure they are comfortable and functional. You may need to adjust the tape or trim any sharp edges for a smooth finish. While duct tape is a simple solution, it may not be the most durable, and you may need to replace it periodically. However, with careful application and maintenance, it can extend the life of your headphones and save you money in the long run.

Applying electrical tape
While there are several methods to repair cracked plastic headphones, electrical tape is a common solution.
Firstly, ensure the cracked area is clean. You can use rubbing alcohol to wipe down the surface, removing any dirt or oil. Once the area is dry, you can begin taping.
Start by tearing off a piece of electrical tape long enough to cover the cracked area, with a little extra on each side to ensure full coverage. If the crack is on a curved part of the headphone, it may be helpful to cut the tape into smaller strips, allowing you to follow the contour of the curve more easily.
Place the tape over the crack, ensuring it adheres smoothly to the surface. You may need to apply gentle pressure to ensure it sticks properly. If the crack is on a curved area, start in the middle of the crack and work outwards, smoothing the tape as you go. Overlapping the tape slightly can also help ensure full coverage and a strong bond.
Finally, check for any sharp edges or uneven areas where the tape meets. You can use your fingernail or a small, blunt object to gently press down any lifted edges, ensuring a smooth finish.
Electrical tape is a simple and effective way to repair cracked plastic headphones, providing a discreet and durable solution.

Reinforcing with wire
If you are looking to reinforce cracked plastic headphones with wire, there are a few methods you could try. One option is to use duct tape and a piece of wire from a wire coat hanger. Cut and curve the wire to fit the shape of your headphones, and then tape the wire onto the outside of the headphones. You can also prevent the wire from rolling by shaping it like an 'S'.
Another method is to drill small holes on either side of the broken part of the headphones. Insert a short, stiff wire into these holes to reinforce the structure, and then seal it with heat shrink tubing.
If you are looking for a more aesthetically pleasing option, you could try using silicone tape. This tape only sticks to itself, so it won't get sticky or caught in your hair. You can also find it in different colours on Amazon.
For a quick fix, electrical tape can be used to wrap around the cracked plastic. However, this may not be a long-lasting solution as it can slip off over time.

Using super glue
Prepare the Surface
Before applying any glue, it's crucial to prepare the surface of the headphones. Clean the cracked area with alcohol or any body deodorant, preferably something with a high alcohol content. This will ensure that the surface is free of dirt, grease, or any other debris that might interfere with the adhesion process.
Choose the Right Glue
Not all super glues are created equal when it comes to bonding plastic. Look for a cyanoacrylate-based adhesive, specifically one designed for bonding plastics. Some options include the Loctite Super Glue Plastics Bonding System or a methyl methacrylate two-part adhesive like Devcon Plastic Welder. These adhesives are formulated to create a strong bond with various types of plastic.
Mix with Baking Soda (Optional)
To create an even stronger bond, you can mix the super glue with baking soda. When combined, these two ingredients create an instant cement-like substance that sets in about 5 seconds. Simply apply the super glue to the cracked area and then sprinkle baking soda on top. Repeat this process a few times to reinforce the bond.
Apply the Glue
Carefully apply the super glue to the cleaned surface, making sure to cover all sides of the cracked area. If the crack is along a hinge or a flexible part of the headphone, try to keep the glue layer thin and flexible. A thicker layer of glue may be more prone to cracking and crumbling over time.
Hold and Secure (Optional)
To ensure that the glued area stays in place while drying, you can use tape or a hair tie to hold the pieces together. This will provide additional support and ensure that the bond sets properly.
Post-Repair Care
Once the super glue has dried, it's important to test the headphones to ensure that the repair was successful. Be gentle during the initial testing phase to avoid any further damage. Keep in mind that super glue repairs may not be permanent, and the bond may eventually fail, especially in high-stress areas.
While super glue can be a quick fix for cracked plastic headphones, it may not always provide a long-term solution. For more complex repairs or if super glue doesn't work, you may need to explore other methods or seek professional help.

Painting over tape
While there are various methods to fix cracked plastic headphones, such as using super glue, duct tape, or electrical tape, you may want to paint over the tape for a more aesthetically pleasing look. Here is a guide on painting over tape:
Preparation
Start by ensuring that the surface you will be painting over is clean, dry, and dust-free. This step is crucial because any dirt or moisture will prevent the tape from sticking properly. If you're painting over tape on headphones, make sure the tape is securely attached to the headphones and not peeling off.
Taping
Select a tape suitable for painting, such as ScotchBlue Painter's Tape. When laying the tape onto the surface, avoid stretching it, as this may cause it to lift or break. Instead, press down firmly and smoothly as you go. Use a putty knife or a credit card to smooth out any air bubbles and ensure the tape adheres well to the surface.
Timing
Once you've applied the tape, wait for a sufficient amount of time before you start painting. Approximately 30 to 60 minutes should be enough for the tape to set and provide a neat, finished look.
Painting
Now, you can begin painting over the taped area. Choose a paint colour and type suitable for the surface and your desired aesthetic. Carefully apply the paint, ensuring you don't accidentally paint outside the taped-off areas.
Removal
After the paint has dried completely, carefully remove the tape. This will reveal sharp paint lines and a professional-looking result. Removing the tape promptly after painting is essential to avoid any paint peeling or residue issues.
By following these steps, you can successfully paint over tape on cracked plastic headphones or any other surface, creating a neat and personalised appearance.
