What to pay attention to when buying headphones from ycbing's blog

1. Pay attention to the labeling of product performance indicators

When buying earphones, pay attention to the performance indicators on the earphone packaging or manuals, because poor-quality earphones are often produced by small factories, and some of their performance indicators are randomly labeled, and some are exaggerated. Headphones generally have a low frequency range of 20-20kHz, a power greater than 100mW, and a harmonic distortion less than or slightly equal to 0.5%. If the above requirements are not met, it is recommended that you still do not buy. It is recommended not to buy a product whose performance is too high in the manual.

2. The quality of product workmanship

The more authentic earphones produced by major manufacturers usually use engineering plastics, so they have a very smooth appearance, and have a certain degree of stress and toughness; headphones with memory card hey have no harshness, fine workmanship, and no roughness of inferior plastics. In addition, the lead wire diameter of the earphone is relatively thick, which can ensure stable transmission, and the wire feels soft and hard; the plug is made very clean and neat, without leaving burrs, and the coating is smooth and even. If the above conditions are not met, it is recommended not to buy.
