1. The first audition track is Cai Qin's "Ferry", which is preceded by three drums, which can reflect the low-frequency diving degree of headphones. The deeper the sound dive, the better the performance of headphones for music. Of course, we can also try to find out whether the low frequency is turbid. Cai Qin's voice at the back can also be used to test the performance of human voice. Through Cai Qin's vocal performance, it can also be reflected whether the voice has a strong musical taste or a strong digital taste, but this feeling is vague. \xd\2. The score of strings and piano used in the score of the second song "I just like you" can test the performance of headphones at high frequency. When listening to this piece of music, we should pay attention to the performance in the middle and high frequencies, and listen to whether the high frequencies are harsh and whether the performance in the middle and high frequencies affects each other. \xd\3. The third song "The Girl in Dabancheng" is a piece of music mainly composed of vocals, which can be used to test the performance of earphones on mid-range vocals. Among them, the male duet from 13 seconds later tests the layering of the voice, so you can feel how many male voices you can hear and whether the layers are clear. \xd\4. The fourth classic audition track of Hotel California, which is a classic song of the Eagles, contains a recording of a live performance in a simulated bar. This music mainly tests the sound field performance of headphones. Applause still rings 2 seconds after the opening. At this time, you can feel whether you have the feeling of being there. At the time of 1 minute and 2 seconds, music, applause and cheers sounded at the same time, which is a good place to test the sound field performance of headphones. You can listen to it in detail at this point. \xd\5. The fifth song "One I Love" is often used to test the detailed performance of headphones. From the beginning to 1 minute and 15 seconds, the song is a female vocalist without the interference of the soundtrack. Through the performance of good headphones, the breath and saliva sounds of the singer will be presented to your ears one by one. If the headphones are not good, they will not be shown and few details will be heard. \xd\6. The sixth "Drum Poem" is a song that shows the control of headphones on sound, and this track is the interpretation of China's traditional drums. Most of the drums in the whole track are short and powerful, which can be used to test headphones to see if there is divergence or turbidity, and of course, to feel whether it is powerful. The lack of sound intensity at low frequencies may indicate that the headphones are not good, or the sound source thrust is insufficient, and an amp needs to be added. \xd\7. The seventh piece of music "Pipa vs. Saxophone" focuses on the performance of pipa at high frequency. By comparing with Saxophone, we can feel the performance at high frequency. There are two main points in high frequency, one is whether high frequency is harsh, and the other is whether there is divergence at high frequency. Many friends here have a misunderstanding about low-resistance headphones, that is, the problem of amp of low-resistance headphones. Through high frequency, it can be shown whether this low-resistance earphone needs amp or not. If the low-resistance earphone diverges at high frequency, it means that the change of current has a great influence on the earphone, so we should consider adding low-resistance earphone. Therefore, this music is more suitable for audition for low-resistance headphones.
