subject: Headset Accessories - Sponge Cover [print this page] 1.The role of the headphones sponge cover
a.Headphones sponge plug non-slip, wear more firmly to prevent the headphones easily from ear off
b.Headset sponge plug to prevent sound leakage, increase bass effect, to fully enjoy the sound from headphones
c.The headset sponge plug to prevent something between the earplugs shell and the ear bones resonate when sound excessive, and ease the discomfort caused due to long wearing headphones ears.
d.Buffer headphones collision with other objects impact shock force to protect the headphones.
2.Headset sponge plug look inconspicuous, but the effect can not be ignored. Some headphones are lack of bass, without ear cotton, feeling relatively high treble, the bass is a bit empty, and the existence of the phenomenon of sound leakage. The installation of a sponge earplugs, better wear closed ear canal, so as to preserve more bass, while strong sound absorption in the porous material of the sponge to absorb a lot of the high-band frequency, making the sound balance toward the lower end. Further more, because of the damping effect changing the vibration characteristics of the diaphragm, a sharp increase in the thickness of the low-frequency sound. To plus ear cotton, bass become very real and phenomenon of sound leakage disappeared, high frequency appear to be more balanced. Therefore, if you feel headphone bass not good enough , do not forget your earplugs fitted ear cotton when listening to music so that can add balance to your headphone, to bring you a better bass performance.
3.The headphones the sponge stuffed earplugs have small pronunciation hole. When you put your earplugs into ears or on the outside, there will be dust through these holes into the ear plugs inside. Earplugs earthquake film is thin, only a few microns, and a little dust will change the vibration of the diaphragm, thus affecting the sound quality, and even cause earplugs damage. Earplugs cotton can protect the earplugs from outside debris.
4.Pick a good headset sponge plug, should pay attention to the following points:
a.Moderate thickness. If the sponge is too thick, it will not only affect the comfort, but also affect the sound quality, loss of balance causing the overall sound.
b.Good density. Density directly affect sponge change of tone,, too sparse sponge makes low frequency too muddy, while the density is too high, the low frequency will be lack of flexibility.
c.Good quality sponge. Good quality sponge can prolong service life.
d.Sufficient elasticity. Various portions of the headset in the ear lining mostly optional sponge do buttress material, in addition to having the above-desired properties, the elasticity is also an important reference value. For some high-end headphones, the elasticity of the sponge can control the diaphragm to the ears of spatial distance, and also directly affects the sense of sound space.
