Many people may not understand why headphones should be cooked. In fact, it's just like the car you just bought needs running-in. There is internal stress in the manufacturing process of earphone diaphragm itself, and there is assembly stress when voice coil is bonded and fixed on the frame. What we call earphone cooking is the process of letting these stresses disappear gradually, making the diaphragm smooth gradually and making a good sound. If the earplug is "boiled" at the beginning, it will gradually loosen its diaphragm, so that when listening to music again, the diaphragm will vibrate very freely and the sound quality will be improved a lot. Therefore, it is necessary to cook headphones.
It is not difficult to make headphones, but it takes time and some skills. First of all, you need a sound source that can be played for a long time. Secondly, there should be music with wide frequency response range, slow dynamic effect, clear hierarchy and moderate high, medium and low components in the sound source. Music with this effect is more effective than ordinary music. Another point is that the output power of the sound source must be large enough. For example, if you want to "cook" the HD600, you can't use an ordinary walkman. HD600 is 300 euros, so you can't come up without a power amplifier. How can you loosen the diaphragm? Generally speaking, walkman is only suitable for earplugs and some low impedance headphones. Generally speaking, it takes a long time to "cook" earplugs with computer sound cards and radios. It takes less time to "cook" with a CD walkman with high output power. It is also the most convenient to praise with FM.
Here I recommend several cooking methods:
Using FM radio, tune the radio to a channel with no signal, and control the volume below 20. At this point, the voice of the hippo chef is equivalent to the white noise dish we usually use for cooking. The new headphones will take about 8 hours to cook every day for a week or two. Although this method is slow, it is safer. At least not because of improper operation.
It usually takes about 10 hour to play different styles of music with CD player or MP3 player, which will easily reduce the life of CD player. But if MP3 is used to play music, it can be played for a long time because of its own structural advantages. Perfect for cooking headphones. At first, use light music, let the headphones relax at low volume 10-30 hours, and then use ordinary music (except rock dance music) at medium volume 100-200 hours; If you don't listen to harsh high notes at this time, you become mellow and natural, the midrange is warm and kind, and the low frequency is no longer a chaotic rumble, but full of details, then you are basically done.
In addition, some people praised headphones for using audio equipment, such as computer stereo. Although this can use some specific software and specific audio CDs. The earphone pot is more professional. However, Bian Xiao does not recommend this method for beginners. Because many of the headphones repaired now are damaged by improper methods when praising the machine. If you are surrounded by professionals, try this method. Generally, white noise dishes and pink noise dishes are cooked alternately. Others are cooked with some specific frequency generators. The advantage of this method is that the earphone can quickly enter the state. Of course, the disadvantage is that improper operation can easily damage the headphones.
I recommend some music to you here. In human voice. Cai Qin and Faye Wong both have good voices. Recommended tracks are Ferry and Sky. Enya's music in sarah brightman's Goddess of the Moon is also good. In addition, Tengger singer singer's voice is full of energy and explosiveness, which is also very suitable for cooking machine. Classical music similar to eagle in California hotels is also suitable. Yan's "The First Drum of Yanhuang" is also a good dish of the cooking machine. In addition, hivi's listening disc covers a wide range and is very suitable for cooking headphones.
