Common Material Analysis of Headphones
It is called polycarbonate in Chinese. It is made of high strength and high price. The disadvantage is that it has poor resistance to organic chemicals. It will turn yellow when exposed to the external environment for a long time and is easily eroded by some organic solvents. It is generally used to make earphone shells with high strength requirements.

PC: It is called polycarbonate in Chinese. It is made of high strength and high price. The disadvantage is that it has poor resistance to organic chemicals. It will turn yellow when exposed to the external environment for a long time and is easily corroded by some organic solvents. It is generally used to make earphone shells with high strength requirements.
PC PET: This is a newly developed and used material. It combines the excellent impact resistance of PC and the chemical resistance of PET and has a lower processing temperature. The disadvantage is that the price is high and manufacturers rarely use it. This material is used unless it is a special lightweight product with a thinner surface shell design.

ABS: The chemical name is acrylonitrile-butadiene-styrene copolymer. It has excellent heat resistance and chemical resistance and is easy to carry out surface spraying, electroplating and other coating and coloring processes. It is widely used and relatively cheap. The disadvantage is that it has poor strength. It is often used by Bluetooth headset manufacturers to make low-end business headset face shells, internal support frames and keys that need electroplating.
ABS PC: commonly known as plastic alloy, it has excellent heat resistance and impact resistance of PC resin material, excellent processing fluidity of ABS resin material, and moderate price. It is often used in middle and high-end sports earphone shell materials. The disadvantage is poor thermal conductivity.
Metal material: aluminum alloy and stainless steel are widely used. The advantages are light weight, high strength, scratch resistance, good thermal conductivity, and excellent texture. The disadvantage is that the process requirements are a bit high, and the processing cost is also high. It is generally used on higher-end sports Bluetooth headsets. For example, the jetblue U8S product surface shell is made of all-metal 304 stainless steel.
