Earmuff patent

In the current earphone market, there are many small-scale earphone manufacturers who focus on personalization, in addition to the existing old-fashioned earphone brands and cross-domain operations that cut into the earphone market from other fields. RHAPSODIO from Hongkong has a history of only three years, but its personalized products have gradually emerged in some international exhibitions, and its director, A Xian, has visited Taiwan Province Province many times to communicate with earphone lovers in Taiwan Province Province. During his recent visit to Taiwan Province, he also talked with Xian about his ideas about products.

A Xian said that although they are a headset brand with a history of only three years, they have their own mobile phone monomer factory, so their mastery of mobile phone headphones is far deeper than that of some brands that buy monomers from other factories. Three years ago, RHAPSODIO launched pocket monster's ring-iron hybrid single earphone, which became famous in one fell swoop. Now, in addition to the headset brand, Axian also has a sales store in Hong Kong to display his own products and products he agrees with. A Xian also revealed that the next step is to set up a direct store in Taiwan Province.

When Xian opened his product display box, he was surprised to find that there were many RSD lines made of different materials. Xian said that wires are very popular products, and at least 50 pieces are sold every month. These upgrade lines are carefully selected by him, and they are all high-quality wires that have passed the military regulations, including the upgrade lines of Liz structure such as pure silver wire and OFC wire. However, A Xian also said that in the future, the product line will be controlled between seven types, and all of them are quite elite products.

In addition to wire, RHAPSODIO's main product is its headphones, and the shell material is also metal recently. A Xian emphasized that although there are many in-ear earphones made of metal materials on the market, RHAPSODIO does not use zinc-chromium alloy which is common on the market, but uses light aluminum alloy after considering the material characteristics and weight. But the best material in his mind is titanium alloy, but it is not used because it is not easy to process.

The reason for using metal is very simple, not just for beauty or texture, but for the characteristics of dynamic headphones. Using the reflective characteristics of metal can reduce distortion and suppress vibration. A Xian also revealed that after finding a cooperative metal 3D printing partner, the future male model products of balanced armature headphones also intend to use a metal shell.

Why do you want to set up your own moving coil monomer factory? A Xian thinks that, compared with the balanced armature, because the technical patents and production process are limited by a few suppliers, the sound elasticity is smaller, and the sound of the balanced armature monomer is detailed, but its response frequency range is limited, and the sense of space is mostly flat, while the moving coil has a natural sense of space and has its own factory, which is also his personal insistence on the pursuit of the natural timbre of the moving coil.

The photo is RTi 1 customized version, and the silver in the middle is the moving coil monomer.

In view of the fact that the general sound of moving coil monomer is not delicate enough, RHAPSODIO provides delicate and natural timbre through exclusive UltraMag technology and titanium vibration mode. The moving coil monomer package is funnel-shaped and can be made into customized moving coil headphones; Although RHAPSODIO only provides the metal shell in the male mold at present, Axian revealed that he has hired engineers with 3D drawing ability to assist in product development, and hopes to provide customized metal headphones in the future.

However, RHAPSODIO's dynamic technology needs a strong driving force, and it is difficult for high-end products to produce excellent sound in ordinary mobile phones. Therefore, he also set out to design a matching headphone amplifier, but he didn't intend to add a DAC cable. It was purely analog amplification, so that players could match their favorite player products, and then the amplifier could meet the needs of the driving unit. As for the product design, it is flat and light, which is convenient to carry with the player product.

However, due to the market demand, RHAPSODIO still provides customized earphones equipped with balanced armature monomers, including ten monomers and six monomers, which are currently produced by traditional injection molding. However, A Xian said that due to the upcoming acquisition of a new generation of balanced armature monomers, the sound of the new balanced armature headphones will be improved, especially in the low frequency part.

However, if we carefully observe RHAPSODIO's current product line, the first attempt of hybrid single earphone with moving coil and balanced armature is now extinct. A Xian said that the current product line is a single monomer technology mainly because of some commercial conditions and his personal preference for the naturalness of dynamic headphones, but this does not mean that RHAPSODIO will no longer launch mixed single headphones, because he has his own new ideas about mixed single headphones.

The picture shows the first generation of hoop-iron hybrid headphones.

A Xian believes that the biggest problem of mixed monomer headphones is that it is difficult to achieve a sense of harmony between two monomers with different tonality. When tuning, it is easy to emphasize the performance of the two monomers in high frequency and low frequency respectively, so that the sound curve presents a V-shape with a serious depression in the intermediate frequency. However, the unique 8-shaped sound stage formed by the characteristics of the two monomers is also the charm of the hybrid earphone.

A xian also made his own comments on the characteristics of the product line. The moving coil product line tends to be natural and delicate, while the balanced armature product line tends to be natural and balanced. The new generation of hybrid single earphone is going to take "madness" as the product feature, hoping to present a more personalized earphone by combining the moving coil monomer with strong low frequency and the moving iron with good high frequency ductility, which is different from the other two product lines. At present, it is planned to launch four railways and six railways.

Since Ah Xian came to Taiwan Province Province and had contact with many friends in Taiwan Province Province, the author also asked Ah Xian what he thought about the difference between friends in Taiwan Province Province and Hongkong. A Xian thinks that there are fewer fans' myths about burning friends in Taiwan Province province than in Hong Kong brands, and there is no obvious preconceived idea. He has a preset position that new brands are willing to test goods through sound, not because their brand awareness is low.

Xian is also a boss who is quite confident in his products. He thinks what he likes is the most important thing. He doesn't want to change the tuning style to cater to market preferences. If he has a strong subjective awareness of his favorite brand and voice, he can buy that product directly. He is also quite confident that people who have heard of RHAPSODIO products can agree with their product value as long as they have no preconceived ideas.

For the future product planning, A Xian said that with the participation of engineers specializing in 3D drawing, the next product development will be more active. In addition to the newly designed metal shell, he personally intends to introduce large earmuffs. He revealed that he was quite surprised after listening to HiFiMAN's HE 1000 before, and thought that the timbre of HE 1000 would be the reference direction for his future earmuffs design.

The author listened to RHAPSODIO brought by Ah Xian a little? In fact, the products are not impressed by the balanced armature series, but the RTi 1 and RD3 dynamic headphones with metal shell are quite refreshing. The sense of space between two dynamic earphones is like the pursuit of large-size closed earmuffs. However, the voice does not retreat excessively, showing a natural and vast style without losing the sense of analysis, and it is not as dull as the Sennheiser IE800, and the overall timbre tends to be bright.

The sound stage of RTi 1 is also considerable. At first glance, the position of the monomer seems to be outside the ear, unlike the performance of in-ear headphones; However, these two headphones also need considerable driving force, especially the RTi 1 driven by mobile phones is basically terrible. Although RD3 performs better on mobile phones, it does not achieve ideal performance. Even the author can predict that these two headphones don't perform well on most music players.

Because the author uses the borrowed HiFiMAN 802U, with the gold MiniBox power amplifier card that emphasizes the driving performance as a reference, and uses RTi 1 to test, the volume has to be cut to close to 5 at low gain, which is close to the single-ended RE400 earphone. I'm afraid it's hard to meet the demand of RTi 1 for the models with battery life as the mainstay.

In addition, Axian also provides several headphones for audition, including a ring of iron headphones for tuning reference, high-purity silver wire quasi-monitoring dynamic headphones, and entry-level headphones targeting at low prices. Can you recognize RHAPSODIO from these products? This brand has only three years of ambition; Maybe? RHAPSODIO? The sound style will not appeal to both refined and popular tastes, but personalized sound is bound to attract some players who pursue unique styles.
