The earpieces of in-ear earphones are as important as the tires of a car. This is because the earpiece must fit snugly in the ear canal to ensure high sound isolation, and at the same time it is important that the earphones are firmly fixed without wobbling. The comfort of wearing is also required. In addition, a certain degree of stiffness is required so that the inner shaft part that joins the nozzle part of the earphone does not deform greatly, and the outer canopy part does not lose the band balance due to wrinkles. It is also necessary to eliminate adverse effects. Various functions are required for parts with a diameter of only about 1 cm.
On the other hand, most of the genuine earpieces that come with earphones are soft types that emphasize wearing comfort. It's a good choice in terms of "good fit", but it tends to fall into unfavorable situations in terms of sound insulation and sound quality. Depending on the product, it is likely that the original performance of the earphone (especially in terms of sound quality) cannot be fully demonstrated. Perhaps because of this situation, more and more users are seeking the best fit and sound quality for themselves by using commercially available earpieces.
Under such circumstances, AZLA's "SednaEarfit" is gaining high popularity. Developed independently by the up-and-coming earphone manufacturer AZLA, the design is based on data obtained by analyzing the ear canals of 788 people. Available in 6 sizes from SS to L, it is a popular product that provides a comfortable fit for a wide range of users.
In addition to the original model for general earphones, there is also a short type that is ideal for complete wireless (TWS), and two types with different hardness. In addition, last year, "SednaEarfit XELASTEC", which uses a TPE (thermal plastic elastomer) material that changes its shape according to body temperature and provides a snug fit, also appeared. It has brought the benefits of high-performance earpieces to even more users, such as preparing a dedicated version for AirPods Pro.
A third option has appeared in such "SednaEarfit". That is "SednaEarfit Crystal".
"SednaEarfit Crystal"The new model also has a wide variety of variations, and is available in a total of 3 series: "Standard", "for TWS" and "for AirPods Pro". The price is 3,980 yen for 1 pair of 3 sizes and 2,980 yen for 2 pairs of 1 size.
