The soundproofing effect of wired headphones varies depending on a variety of factors.
First, the design type of the headphones has a key impact on the soundproofing effect. In-ear wired headphones usually have a good soundproofing effect. This is because they can penetrate deep into the ear canal, forming a relatively closed space, effectively blocking the outside sound. For example, some high-end in-ear headphones are equipped with earplugs of various sizes, and users can choose according to the size of their ear canal so that the earplugs fit tightly with the ear canal. When the earplugs fit well with the ear canal, it is like installing a barrier for the ear, which can greatly reduce the interference of external environmental noise. For example, using in-ear wired headphones in a noisy subway car or a busy street allows users to immerse themselves in their own music world and isolate the outside world from human voices, vehicle noise, etc.
The soundproofing effect of head-mounted wired headphones also varies. If the head-mounted headphones adopt a full-ear design and the material of the earmuffs has good sealing and sound absorption, the soundproofing effect will also be better. The earmuffs of this type of headphones can cover the entire ear and reduce the input of external sounds through physical isolation. For example, some professional studio headphones use soft memory foam and other materials for their earmuffs, which not only fit the ears tightly, but also absorb some external sounds, creating a relatively quiet listening environment for users. However, if the earmuffs of the headphones are not well-fitted, or the material is thin and too breathable, the sound insulation effect will be greatly reduced.
The headphone cable itself has no direct effect on the sound insulation effect, but it may indirectly affect the user experience. If the headphone cable is too short, the user may not be able to use the headphones normally in places that require a good sound insulation environment (such as a quiet corner); if it is too long, it may cause inconvenience during use, affect the stability of the headphones, and thus affect the sound insulation effect.
In addition, the frequency response range and noise reduction technology of the headphones are also related to sound insulation. Some Wired Headphones have active noise reduction functions, which monitor the external environmental noise through the built-in microphone, and then generate sound waves opposite to the noise to offset the noise, further improving the sound insulation effect. In environments with severe low-frequency noise, such as on airplanes or near factory workshops, this type of active noise reduction Wired Headphones can significantly reduce noise interference.
In short, the sound insulation effect of Wired Headphones depends on many factors, such as the design type of the headphones, the material and fit of the earmuffs or earplugs, whether there is noise reduction technology, etc. When choosing Wired Headphones, consumers can choose the appropriate product according to their usage scenarios and their needs for sound insulation.
