Cooking machine: \x0d\ 1. Remember that the way to cook headphones is "step by step". At first, let the headphones play slowly at a low volume 10-30 hours, and then cook with ordinary music (except rock and dance) at a medium volume 100-200 hours; If the treble is not harsh at this time, it becomes round and natural, the alto is warm and kind, and the low frequency is no longer a chaotic rumble, but full of details, then congratulations, OK, don't be eager for quick success. \x0d\ 2。 First, you can't work continuously for too long! Because the voice coil has resistance, it will heat up after working for a long time, and it may burn out the voice coil! It's best to stop for a few minutes every two hours and then continue. Second, the volume must not be too high. Earplug diaphragm is a very fragile material. If the volume is high, the stroke of the voice coil will be large, which will lead to the looseness of the voice coil and the deformation and even tearing of the diaphragm. \x0d\ 3。 Turn on the full frequency in order to get through the weird classics of headphones. The method is to play it continuously with a variety of different frequencies. Generally, it will rest after one to two hours, but the volume should not be too loud. It will have obvious effects in about ten hours. \x0d\ 4。 The next thing to do is the sense of music (especially high-quality headphones will be very helpful). Most of them use pure music soundtrack, with high audio quality and wide range. Personally, I prefer City of Sorrow and Happy Hotel. Use the same method as above. \x0d\ 5。 Choose your favorite music to play, so that 3300 can play this type of music more fully. In fact, if the earphone is not boiled, it will be used for a long time and the sound quality will be improved. \x0d\ 6。 It is suggested that you listen naturally, don't deliberately cook, or you can use a safer method to tune your mobile phone to the radio and find a position without channels. At this position, you can hear the explosion of current, and cook at the volume of 20% 10- 12 hours. \x0d\ You can also download the audition CD on the Internet. Don't listen to ups and downs of music at first, such as rock and roll, but listen to some soothing music.
