After long-term use, the sound of Wired Headphones may become smaller or noisy, which is usually caused by a variety of reasons.
First, the sound unit of the headphone may be damaged. Long-term high-volume use will cause the diaphragm of the sound unit to vibrate excessively, resulting in its elasticity weakening or even physical damage, which will affect the output quality of the sound, making the sound smaller or distorted noise.
The headphone cable is also a common source of problems. Long-term bending, pulling and friction may cause the metal wire inside the headphone cable to break or have poor contact. Especially at the connection point between the plug and the headphone, and in places where it is often bent, the wire is prone to open circuit or short circuit, which will cause poor transmission of the sound signal, and then make the sound smaller or produce noise.
The earplug or earmuff part of the headphone will absorb dirt, grease and sweat due to long-term contact with the skin. These pollutants may block the sound outlet of the headphone, affect the propagation of sound, and cause the sound to become smaller. At the same time, if it enters the inside of the headphone, it may also affect the normal operation of the sound unit and produce noise.
In addition, the wear or oxidation of the headphone plug will also affect the sound. During the frequent plugging and unplugging of the plug, the surface coating may wear out, resulting in increased contact resistance and affecting the transmission quality of the audio signal.
In addition, the use environment will also affect the headphones. If they are often used in a humid and dusty environment, the internal parts of the headphones may be damp, rusted or corroded by dust, thus affecting the sound effect.
Finally, if the headphones have been hit or dropped violently, the internal structure may also become loose or damaged, causing the sound to become smaller or noisy.
In summary, the sound of Wired Headphones becomes smaller or noisy after long-term use, which may be due to the combined effect of multiple factors such as damaged sound units, headphone cable failure, earplug blockage, plug problems, use environment, and physical damage. Regular cleaning and maintenance of headphones, proper use and storage can extend the service life of headphones to a certain extent and maintain good sound effects.
