What material is used for the headphone shell, the headphone shell manufacturer will introduce you one by one

Metal

Metal materials refer to materials with properties such as luster, ductility, easy electrical conductivity, and heat transfer. Generally divided into two kinds of ferrous metals and non-ferrous metals. Ferrous metals include iron, chromium, manganese, etc.

The metal earphone shells are also black and colored, which are slightly heavier than other materials.

Silicone case:

Silicone cases are a well-known type of protective case. Soft texture and slightly slippery feel have been popular in the market for many years. From shoddy street stalls to well-crafted individual brands, the market share has always maintained a leading position. Because of its cost-effectiveness, silicone cases were loved by people when MP3 and iPod became popular. There are two types of silica gel shells, one is organic silica gel and the other is inorganic silica gel. The earphone box silicone sleeves on the market basically belong to the former. Silicone has many advantages, such as high temperature resistance, good weather resistance (not afraid of ultraviolet or ozone decomposition), insulation, and material (will not change with animal bodies). In addition, people choose the silicone case because of its feel, and it can absorb the impact of some bumps on the mobile phone, thereby reducing the damage to the earphone box and earphones.

In addition, the silicone case is waterproof and inexpensive. However, there are still shortcomings. Due to poor air permeability, long-term wear will cause the earphones to accumulate heat, and cheap silicone has a pungent odor. Moreover, the silicone case itself is slightly sticky and easily absorbs dust. In addition to the above precautions, the purchase of earphone silicone shells is also worth noting.

TPU soft shell

TPU is soft. Like silicone, it belongs to soft rubber products. TPU belongs to plastic. The product is made by injection molding process. moulds to make products. Silica gel belongs to rubber, and the molding process is vulcanization molding. The silicone mold is opened up and down. Cut pieces of silicone raw materials, put them in the mold, and heat and pressurize to make the product. Generally, plastic products will have a plastic inlet, which needs to be trimmed after the product is injection molded. If the trim is not good, the appearance will be affected.

From the feel of the hand, the hardness of TPU is generally harder than that of silicone, and the elasticity of hand pinching is stronger, while the elasticity of silicone is slightly worse. TPU can be compared to the feel of muscle, and silicone to the feel of fat.

From the outside, TPU can be made very transparent, but silicone cannot. The most transparent one is very hazy, like a thick fog. It is precisely because of this transparent feeling of TPU that it is more popular with users.

There are still many high-grade TPU products, with strong selectivity and more pattern changes than silica gel. The disadvantage of TPU is that it is easy to deform and turn yellow. After three or four months of use, if you just buy a light-colored product such as transparent white, it will easily turn yellow. If the material is not good, the surface may even fog up. Or sticky hands.
