On June 23, 2009, I started a MX760 in Kunming Baiteng Digital Plaza Experience Hall, the general agent of Yunnan Sennheiser. After careful cooking, the sound is like nature!
Today, I will write out my experience of cooking machine and share it with you.
The following is based on my understanding and experience. It is impossible to perfectly correspond to various brands and models of headphones. So please think twice before you do so as not to cause unnecessary economic and material losses. I will not be responsible for all the consequences that follow. I hope you can understand!
1. What is a cooker?
Boiling machine, in short, is the process of making the newly bought headphones have the best sound quality.
When listening to songs with headphones, we can only hear the sound when its diaphragm ring vibrates. The process of boiling machine is also the process of accelerating the aging of diaphragm ring in earphone.
Then some friends will ask, will accelerating the aging of diaphragm ring shorten the service life of headphones? Will it damage the sound quality of headphones?
The new earphone diaphragm ring has poor mechanical compliance, which leads to large distortion. After a period of use, the compliance gradually improved.
The distortion will gradually drop to normal level. Proper machine maintenance will not shorten the service life of headphones, nor will it damage the sound quality of headphones. It will only make the sound quality of headphones better and better. Just like cars and so on. It has a running-in period. It is a truth that using it slowly will improve performance. So don't worry.
Whether it is low-end headphones or high-end headphones, the sound quality has improved to a certain extent after the machine is cooked, but the high-end products can feel it better.
2. How to cook the machine?
Cooking must be done step by step. Otherwise, it will not only fail to improve the sound quality, but also cause permanent physical damage to the headphones due to improper methods. As mentioned above, the mechanical compliance of the diaphragm ring of the new earphone is poor, which means that the motion stroke of the diaphragm is too short when it vibrates. If you use strong drugs from the beginning, you will damage the diaphragm.
There are roughly two methods for cooking machines:
1. Music cooking method. It is also the cooking method explained today.
Music cooking machine is the most commonly used method. It is also a relatively simple method.
2. Noise cooking.
Radio method: tune to a place where there is no signal, and its noise is also called white noise.
⑵ Software cleaning: use professional cleaning software, which comes with noise audio files. (This method is not recommended, because non-professionals cannot master the appropriate volume and noise frequency. It is easy to damage headphones, and there are too few professional earphone cleaning software resources to download. )
Note: the software of the cooking machine is different from the software of the cooking stereo! The power of stereo and earphone is different! If you use the software of the rice cooker, the damage rate will be greatly improved! And there are many such examples!
3. Detailed steps and what should I pay attention to?
The steps of the cooking machine are roughly divided into three parts.
1. Warm up.
Don't use too much volume when warming up. Don't listen to electronic, metal, dance music and other music with headphones.
It turns out that when the diaphragm of the new earphone vibrates, the motion stroke is too short. Because the volume is too loud, listening to these concerts will make the diaphragm vibrate greatly and bring physical damage to the headphones. For example, careless power overload, excessive amplitude will lead to the flapping of diaphragm and so on. The earphone and earplug diaphragm is a very fragile material, so the volume must not be too large!
Choose the right machine cooking equipment.
①MP3
The best thing about MP3 is that it can work continuously with sufficient power without damaging the hardware. Besides, it's cheaper than a CD player. It is easy to carry. Using mid-range or high-end MP3 players can not only play common formats such as MP3 and WMA, but also play formats such as AAC and OGG. Although AAC and OGG are lossy formats, their sound quality is better than MP3 and WMA. Some MP3 players can play lossless formats such as APE.
Note: When using MP3 format, you must use 320KBPS files! When downloading online, you will usually find the largest file. After downloading, you must listen to it yourself to see if the parameters are 320KBPS files.
Listen to the possibility of preventing the loss format below 320KBPS from being converted to 320KBPS! You can usually hear it if you listen carefully!
②CD player
Everyone knows that the sound quality of CD player is absolutely the best. But CDs are expensive, and there are great restrictions when they are used to repair machines.
Because the principle of CD player and MP3 player is different, the heat and physical damage are also different. When using a CD machine to cook the machine, the CD machine cannot be used for a long time, otherwise it will damage the machine.
For the above reasons, I personally recommend MP3 player. Don't call any equalizer effect when cooking!
Choose the right song.
Whether you use MP3 or CD, it is very necessary to cook songs properly. Be sure to choose soothing music when warming up!
Highly recommended: Cai Qin-
Generally, the volume of music you usually listen to is around 30%-40%. If you find it difficult to estimate, use 30% of the total volume!
Don't work for too long when the machine is boiling.
Because the earphone voice coil has resistance, it will heat up and burn the voice coil after working for a long time. Generally, if you cook for about 2 hours, you will rest for a few minutes, then cook again, and so on. Generally, the preheating process takes 24 to 30 hours.
It is worth noting that the headphones should not be plugged and unplugged while the player is running, because if the headphones are plugged and unplugged with electricity, the current and voltage will be overloaded instantly, and the headphones will be partially burned.
The correct way is to plug in headphones when you don't turn it on, turn off the volume, and slowly adjust it to the appropriate volume after turning it on; Similarly, after the machine is completely powered off, unplug the headphones and turn off the volume to prevent it from being too loud next time.
2. Formal boiling machine
After the preheating is completed, the normal and long boiling process can be carried out!
This process should not be less than 200 hours. Otherwise, the machine will not be in place. In the next stage, amplifying dynamic music will also damage headphones. This step took me 300 hours! Friends can think about it!
(1) 100 hours ago
Or choose to write a soft song and play it in a loop. Boiling time is still 2 hours rest. You can do it with 40%-45% of the normal listening volume or 40% of the total volume.

(2) Intermediate100h
You can listen to some of your favorite pop music. There are no fixed songs. The songs mentioned above can also be mixed in. You need to adjust the interval of some songs, such as soothing songs → songs with strong rhythm → soothing songs → songs with strong rhythm. In this intermittent mode, the volume can be appropriately adjusted to about 50%-55% of the normal listening, or 50% of the overall volume.
The boiling time can be extended to three hours' rest.
(3) 100 hours later
You can choose some songs with strong rhythm to cook the machine. For example, JPOP songs, Japanese anime songs MJ songs, or metal rock with a light rhythm. You can also use some pure music sources with high quality and wide audio frequency to cook the music of headphones, such as and so on.
There is no fixed music to use in this part, just look at what your headphones are missing! In the middle and late stage, headphones can be strengthened according to their lack of audio. For example, at 180 hours, you find that the headphones are short of treble, so you can find some treble songs to strengthen the treble analysis of the headphones. After nearly 30 hours of strengthening, the treble resolution of headphones has been quite perfect.
The interval mode is still based on the above. For example, soothing songs → rhythmic songs → rhythmic songs → soothing songs → rhythmic songs → rhythmic songs.
The cooking time can be appropriately extended to about 3.5 hours for rest. It is best not to use it continuously for more than 4 hours. The volume can be 60-65% of your normal listening volume or 60% of the total volume.
After the whole cooking process is finished, it can be put into normal use.
3. Normal use.
You can listen to your favorite songs at this stage! Now about 95% of the effect of headphones can be reflected. The volume won't bother you anymore! But it is best not to use it continuously for more than 4 hours, so as to avoid extreme joy and sorrow.
This stage is a long-term sound quality stabilization stage. The time is usually 1.5-2 months.
Today's headphones don't have to endure for hours like the first and second stages. They sound like nature and need to be used continuously every day! Listening to songs for 2-4 hours every day is the best way to achieve perfection!
Four. abstract
Cooking must be done step by step. Don't be impatient! Follow the steps strictly! Even the exquisite headphones can be easily done!
And to be clear, not all headphones will improve their sound quality after being boiled. There are many such examples, so don't get your hopes up. As the saying goes, the greater the hope, the greater the disappointment …
Finally, good luck!
