The music used for the burn-in includes Ou Ruiqiang's "I Just Like You", Faye Wong's "Sky", and Beethoven's "Pathetique".

1. Ou Ruiqiang's "I Just Like You"

The string and piano soundtrack used in the soundtrack of "I Just Like You" can test the performance of headphones at high frequencies . When listening to this music, you should pay attention to the performance of the mid- and high-frequency, listen to see if the high-frequency is harsh, and whether the performance of the mid- and high-frequency affect each other.

2. Faye Wong's "Sky"

This song "Sky" from the mid-1990s was once a top-notch audition single at that time, and was highly praised by old audiophiles. The single is well-recorded and has an excellent balance of genres. The vocals are sweet and ethereal, and the imaging and positioning are top-notch. The combination of musical instruments is natural and refreshing. Therefore, even after 10 years, it still has a strong audition recommendation value even today. However, without good equipment, it is difficult to appreciate the beauty of it.

3. Beethoven's "Pathétique"

Beethoven's famous "Pathétique" sonata must have been heard by many friends. But it is such a piece of "Pathetic", but who can bring out such a pure artistic conception? Although many piano masters have always liked to show their hands on this work, they had to bow before this version. After all, Rubinstein is Rubinstein.

In addition, Rubinstein is playing a beautiful-sounding Steinway piano here. The richness of the sound levels is enough to test the dynamics of the sound and the balance of each frequency band.
