How to distinguish the authenticity of iron triangle headphones?

1. Anti-counterfeiting can be verified by official means, telephone, website, SMS, etc.

2. See if the appearance is smooth, the workmanship is fine and the feel is good. Whether the plastic used to make headphones has a rough feeling. In addition, the lead wire is thicker than the wire diameter. Then pinch the wire hard by hand to see if it is soft and not stiff. If the lead is hard and the material used is poor, the quality of the earphone is not much better. The last thing to see is whether the plug of the earphone is standardized, neat and burr-free.

3. Audition, which is very important. When listening, it's best to choose a dynamic CD or lossless music with first-class sound quality, which can make headphones play their potential better. Pay attention to whether the high notes are clear and the low notes are powerful when listening.
