The newly bought headphones are not stimulated by current when they leave the factory, and the unit, diaphragm and wire are in a brand-new state. Without preheating, the sound will be very tight and hard, and it will not be able to show its proper timbre. So the newly bought headphones need to be boiled. The following methods are recommended:

Audition disc, the volume is 30%-40%, and it will be played continuously for 12~ 14 hours (FM music station is also acceptable). After a day's rest, different styles of CD 5 ~ 10 hours (including vocals, symphonies and pop music) will be selectively played continuously;

Another method is to use pink noise or white noise as the signal source. The energy of white noise in each frequency band is the same. Theoretically, the sound of each pitch is the same, and the pink noise sounds the same. But in fact, the sound energy is reduced by 3dB every 8 degrees, which sounds softer. Remember to stop cooking. For example, cooking 12 hour, rest 65438+.

Generally speaking, the first week of new headphones is cooking time. Then let nature take its course. After one month, the sound of headphones has been 95%, and after six months (2 hours a day on average), it can reach its best state.

Extended data:

1, the music used to cook headphones should be music with little motivation to "cook". For headphones with higher impedance and lower sensitivity, the cooking time should be increased accordingly, and the overall cooking time of headphones should not be less than 50 hours;

2. The diaphragm of the earphone has its service life, just like the speaker of the sound box, but because the amplitude of the diaphragm of the earphone is very small, which is much smaller than that of the speaker diaphragm, the service life of the earphone will be longer. If it is used normally, it will not be a problem for decades, so it is very important to cook the headphones to the right volume;

3, high-end headphones should be carefully boiled, do not use electronic music, electronic music bass component is too strong, for high-sensitivity headphones may appear overload, causing irreparable physical harm.
