For example, regarding sound, the coincidence set given by Weston is the most common. Some headphones will send three more sets. The standard silicone sleeve is different to wear and the hearing is different. Of course, high school and low frequency have also changed. I only refer to one earphone brand here, and all other headphones are the same. PS: The size of the silicone sleeve is also related to the sound.
The two-stage sleeve is deeply inserted and has good sound insulation, which is relative to the three-stage sleeve. One-piece sleeves are the most common. According to my personal hobby, I don't know if it's right. I prefer single-section sleeves. I'm cx400ii.
What is the use of rubber sleeve for in-ear earplugs?
Appropriate earmuffs will not only improve the sound quality of in-ear earplugs, but also increase the comfort of wearing them, which has a direct impact on the user's experience. There are indeed many kinds of earmuffs for earplugs, which have different effects on sound quality.
1, silicone earmuffs
Most earplugs in the market are equipped with similar earmuffs, and the most common one is silicone earmuffs. Generally speaking, in-ear earplug products will be equipped with at least three different rubber sleeves, which can reach more than 6 pairs, which will make the products look more sincere. But the difference between these rubber sheets is not only the change of size, but also their influence on sound is obvious.
Small earmuffs (S-shaped) are characterized by relatively clear sound but small sound field; Medium earmuffs (M-type) are basically attached to earplugs by default, which has strong sound equalization adaptability; The large earmuffs (L-shaped) are opposite to the small earmuffs, and the sound field is large and surrounding, but the sound is relatively dull.
2._ C。
Sponge earmuffs are the most common earmuffs in flat-head earplugs, which have a wide range of applications and are almost the only choice for flat-head earplugs.
Its characteristic is to enhance the relatively weak low frequency of flat-headed earplugs, and it will also have a better touch when worn. But from another point of view, the demand for earmuffs of flat-headed earplugs is not as great as that of in-ear earplugs, because most flat-headed earplugs can listen directly without sleeves, and the sound is more transparent, so whether to use sponge earmuffs depends entirely on the user's listening orientation.
3, memory sponge earmuffs
In terms of sound, the low frequency of memory sponge earmuffs is the most impressive, and it will have a good effect with some excellent earplugs with low frequency. But wearing this kind of earmuffs for a long time always has a feeling that the ears are blocked, and the air permeability is not good. Wearing them for a long time will bring out more foreign bodies, which is not conducive to health and hygiene.
4. Columbia Collection
The sleeve we often hear about is actually a kind of silicone sleeve. The sleeve is made of mixed silica gel, which is an accessory of Sony earplug products. The model size is larger than that of ordinary silicone sleeve. In addition to s, m, l, there are four sets of earmuffs: s, MS, ML and LL. In addition, there are S, M and L soundproof earmuffs filled with sponge between silica gel layers. The price is also relatively expensive, and the price is slightly different according to different models.
In practical experience, the low-frequency quality and sound field of the large-size sleeve are obviously enhanced, and the sound density of the small-size sleeve is higher, which is the sound difference between it and the ordinary silicone sleeve. The sound insulation sleeve filled with sponge is a bit like the C sleeve mentioned before. In addition to better sealing, the sound becomes more concentrated.
5, SpinFit earmuffs
SpinFit earmuff is a silicone sleeve. The difference is that SF has a long sound guide tube, which can make it deeper into the ear canal than other earplugs, and at the same time, it can be adjusted adaptively according to the user's ear canal, keeping it extremely comfortable to wear, and there is no blocking feeling of C sleeve. SpinFit even filed a patent for this design.
Hearing, the sound permeability and resolution of SF sleeve are obviously superior to other earmuffs, and the sound field and low frequency are not weakened, which is undoubtedly the best choice for dark headphones, while bright headphones may have harsh sound.
6, multi-section earmuffs
It is also made of silicone, and it seems that a number of earmuffs are listed together from large to small, but to be honest, the shape and size of this earmuff are not acceptable.
In addition to the three-stage set, the author can barely try the two-stage set, and its size will obviously affect the experience. Large-size double-section bushing has good sound insulation effect. It sounds full after wearing it. The large sound field is its advantage, but the resolution will decrease slightly, but it is not obvious. Suitable for earplugs with sound stimulation.
7. Cylindrical sleeve
It is an accessory of Final_ series earplugs, and it should not be suitable for other headphones in appearance. It can cover the whole cavity of the earphone, the length is similar to that of a cylindrical earphone, and the fit is not as good as that of a traditional rubber sleeve.
In terms of sound performance, the analytical power is improved quite obviously, the sound field is narrowed a little, and other aspects have not changed much.
