1. Remember that the method of listening to headphones is "gradual". Start with softer music, let the headphones soothe for 10-30 hours at a lower volume, and then use normal music (rock, rock, etc.) (Except for dance music) burn for 100-200 hours at medium volume; if the high notes are no longer harsh and become rounded and natural, the midrange is warm and friendly, and the low frequencies are no longer a mixed rumble, but full of details, then Congratulations, OK. You must not be eager for quick success.

2. First, you cannot work continuously for too long! Because the voice coil has resistance, it will generate heat after working for a long time, and it may even burn 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 loud. The earplug diaphragm is a very fragile material. If the volume is high, the movement range of the voice coil will be large, which will pull the diaphragm violently, causing the voice coil to loosen, the diaphragm to deform or even tear, etc. wait.

3. Turn on the full frequency, the purpose is to open up the extraordinary meridians of the earphones. The method is to play continuously with a variety of different frequencies. Generally, you can play it continuously for one to two hours and then take a rest, but the volume should not be too high. Visible results will appear after about ten hours.

4. The next thing to do is to create a sense of music (especially high-quality headphones will be very helpful). Most of them use some pure music sound sources with high-quality audio and wide range. My personal favorites are, Sad City, Happy Hotel, etc., use the same method as above.

5. Select your favorite music to play, so that the 3300 can play more fully when playing this type of music. In fact, the sound quality will improve to a certain extent after using the earphones for a long time without burning them.

6. It is recommended to listen naturally. Don’t deliberately cook. You can also use a safer method. Turn your phone to the radio and find a location with no channels. If you can hear the chirping sound of electricity, Cook in this position for 10-12 hours at 20% volume.

You can also go online and download an audition disc. At the beginning, don’t listen to rock and roll music, but listen to some soothing music.
