1. Introduced by the headphone manufacturer, choose according to the quality of the earmuffs: as we all know, the biggest feature of the earphone is its closed in-ear design, which can eliminate the interference of the environment to the listening to the greatest extent, and the sealing performance depends largely on the quality of the earmuffs. For the quality of earmuffs, there are two common earmuffs on the market: silicone sleeves and sponge sleeves. Among them, the sound insulation effect of sponge sleeves is average. Compared with them, silicone earmuffs can form a better sealing environment and create the quietest listening. Experience, and good quality headphones are also equipped with several sizes of in-ear silicone earmuffs to meet the needs of users of different ear canal sizes;
2. Earphone manufacturers explained that the choice is based on the sound unit: the diameter of the earphone sound unit affects the sound quality of the earphone. The better earphones currently on the market generally use a 9mm diameter sound unit. This diameter design allows the sound quality to be output. The time is more vigorous, the low-frequency dive depth is greater, the sound quality is pure and durable, and the details are good. Therefore, when buying headphones, you should pay more attention to the parameter of the pronunciation unit diameter in the product description. If it does not reach 9MM, do not buy it;
3. Overview of earphone manufacturers, choose according to the wire of the earphone: The quality of the earphone wire affects the durability of the earphone. At present, cheap earphones on the market often use inferior soft rubber as the production material of the wire, which seriously affects the service life of the earphone. The general use time will not exceed half a year; while the good quality headphones will use high-quality TPE wire as the production material, which has the advantages of high elasticity, anti-aging, good corrosion resistance, and can effectively avoid cable entanglement and output The sound quality is particularly pure.
