How to identify the source of surround sound headphones failure

Headphones have become popular and indispensable in everyday life with the advent of portable music players, music applications, and portable consoles. More commonly, surround sound headphones now accompany their owners to the gym, on morning jogs, on public transportation, and even at home while they do housework. 

Due to repeated manipulations, these small, delicate accessories become dirty and deteriorate. To determine the optimal solution for repairing the headphones, it is necessary to determine the source of the anomaly.

Malfunction test 1:

  • The earbuds are inserted into the ears;
  • Put on music;
  • 90° bend the wire;
  • Your thumb should be slid along the wire;
  • If the sound is intermittently cut off, the issue is with the cable.

Malfunction test 2:

  • Connect the headphones to the music player or phone via the headphone jack;
  • Sustain pressure on the jack;
  • If the sound is audible only when the plug is pressed, it is almost certainly defective.

Malfunction test 3:

  • Plugin the headphones;
  • If no sound is being transmitted, change your earphones;
  • Connect your new earphones;
  • If they function normally, the issue is with the in-ear earphones.
  • Restore the headphone cable to its original state

If the issue is with the cable, there are a few steps you can take to resolve it.

Malfunction located

Once you have located the faulty component, secure it with tape. Cut through the cable insulation with a cutter or knife and remove approximately 1 cm. Carry on cutting until you reach the damaged wire. Divide the cable in half. If one of the inner wires is severed, cut both sides of the cable and adjust the length of both ends;

Assemble the wires, ensuring that the stripped wires of the same color are joined properly. Create a braid or a splice in the line. Melt a piece of tin at each splice with a soldering iron to secure the connections. Create an electrical sheath out of rubber to protect the cuts. Wrap the cable connections in the sheath and shrink the sheath with a heat gun. shut down volume

Making repairs to the jack

Frequently, it is the jack plug that is damaged as a result of rough handling. Purchase a replacement jack plug, preferably one that is spring-loaded and the same size as the defective one. Unscrew the old plug or cut the cable approximately 2.5 cm from the plug. Strip the wires using the appropriate pliers. 

Place the plug’s housing and spring, as well as a sheath, on the cable. Connect the cable’s wires to the plug’s pins, ensuring that the uninsulated copper wire is connected to the body pin (the longest metal part) and the insulated wires are connected to the ring and tip. A small amount of solder is used to secure the assembly in place.

Screw the housing onto the spring to assemble the plug. Ascertain that the earphones function properly.

Adjusting the earcups

For comfortable listening, it is critical to have good earpieces. Remove the earcups first. With a Philips-head screwdriver, unscrew them. Remove the earpieces’ foam. Lift the dome by inserting a spudger or a flat tool into the opening at the base of the earpiece.

If the wires become loose, simply reconnect them to the small metal pins, taking care that they do not come into contact. Disconnect the rubber gasket that surrounds the central capsule and conical driver. Install a driver without touching the diaphragm, if necessary gluing it in place.

When repairing headphones, take the following precautions:

Whether you are a do-it-yourself enthusiast or a casual music listener, here are some precautions to take to safely repair defective headphones.

To master the technique, it is recommended that you practice on inexpensive headphones;

When using the soldering iron, take care not to leave it plugged in for an extended period of time to avoid damaging the plastic or soldering joints.

It is possible to create silicone models to replace the rubber gaskets on button earphones;

Occasionally, while using the earphones, the cable at the base of the jack plug twists becomes damaged and creates a false contact.
