The iron triangle created female poison. At the beginning, people in China listened to music with iron triangle and found that it had no bass, but the sound in the area with high frequency deviation was very nice. Generally, female voices are high-pitched, not necessarily Japanese, and everything is fierce. I think the good days in Song Zu Ying all sound nice, delicate, moist, sweet, touching and deeply rooted in people's hearts, so they are poisoned.

Especially at that time, almost all earphones did not pay attention to this part of the frequency, so the iron triangle took the lead in opening the female poison market, and business opportunities took this opportunity to vigorously promote female poison and promote the iron triangle. With the iron triangle headphones, everyone is keen to start looking for songs sung by female poisonous music, female high-definition singing and soprano singing.
