When we go out, we may encounter a variety of different environments, which are not as quiet as at home. Therefore, the sound insulation effect of earphones is very important for us to get a good voice effect and music quality in noisy external environment. But what kind of earplug and earplug sleeve will have better sound insulation effect?

Bluetooth headset earplug and silicone cover

Bluetooth earphones are mainly divided into headset and in ear earphones according to the type of wearing. Most of the headset earphones adopt semi open design. There will be some sound holes on them to facilitate sound diffusion, which can ensure a more natural sense of hearing. Generally, it is common in high-end hifi earphones, but the disadvantage is that there are not too many sound insulation effects, which is most suitable for home listening. The in ear Bluetooth earphone earplug is generally designed with a totally closed cavity, which not only makes the sound easier to gather, but also has a better sound insulation effect, which is suitable for outdoor use.

Because in ear earplugs have better sound insulation than headphones, most of the Bluetooth earphones sold in the market are in ear earplugs. And because different sizes of earmuffs have different experiences and different sound insulation effects in use, the manufacturers will generally present different sizes of earmuffs for users to choose the right size to use.

Silicone earplugs of different sizes

In addition, the shape of the earplug sleeve also directly affects the sound insulation effect of the earplug. For example, the sound insulation effect of the square rubber sleeve at the front end will not be too excellent. Therefore, most of the silica gel sleeves sold in the market are of circular design. In order to further improve the sound insulation effect of the earplug, some manufacturers use the unique two section sleeve and multi section sleeve.

The material used in the earplug sleeve is also an important factor affecting the sound insulation effect of the earplug. At present, most in ear Bluetooth earphones use soft silica gel earplugs. However, in order to improve the sound insulation and wearing comfort, many manufacturers use more expensive inert sponge rubber sleeve to achieve better sound insulation effect.
