At this time last year, Shaoyin released the aeropex as800 product. At the beginning of our experience article, we mentioned that “Shaoyin is a company from Shenzhen. They are small in size and have a small variety of products, but they are well-known in the circle of running enthusiasts and so on.”. < / P > < p > one year later, they released openmove, a product for more general public users. Shaoyin is no longer limited to the hot running group. They hope to let more people know themselves through openmove. < / P > < p > the translucent packaging is very similar to betas, which is our first impression when we see openmove. Open the package, we received the evaluation machine is “pure white”, in fact, it is a combination of white main body and silver decoration, which is relatively simple and clean. In addition to white, there are color matching such as mysterious grey, energetic powder, trendy blue and wild green. From this, we can see that openmove is different from the previous products: they will reduce the professional atmosphere of bone conduction earphones. The name “openmove” also embodies this idea. < p > < p > the earphone body is still a bone conduction unit on both sides and a connecting mechanism in the middle. This time, the connection bridge at the back is more pure, which makes the earphone look as if it has only two sides. The volume + / -, and the power button are still hidden on the right side. The play key is integrated into the silver decorative strip. The position is still on the left side of Shaoyin habit. However, the sense of existence is very low, which can’t be seen. < / P > < p > the charging port of the headset has also been replaced by usb-c. compared with the magnetic contact of as800, it does not look so high-end, but it is a popular way for the masses. There is a good dust cover on the interface surface, which can make Shaoyin meet the waterproof standard of IP55. < / P > < p > the stickers on both sides are naturally excessive with the titanium connecting bridge behind. According to Shaoyin, different colors can be pasted here, which is also a personalized expression of young people. Can general users use the previous bone conduction earphones? Of course. Although its technology itself originated from military products, Shaoyin transformed it into a civilian product. However, due to the function and marketing relationship, the product positioning always had the flavor of sports accessories, so it was welcomed by “marathon” fans and had a high recognition in that circle. This is the success of Shaoyin, and it is also the constraint they have to solve now. If a company wants to be bigger, its product audience will be more. For example, it is designed for easy life. Shaoyin claims that the project engineers of openmove wear the earphone during the 20 hour flight from China to the United States, just to test the long-term comfort of the earphone during the long-distance journey. < / P > < p > the actual experience is that this product does not have the feeling of a chuck, and the tightness is appropriate (this also depends on the head shape and head circumference, the author’s head circumference is 59cm); we tried it, and the rope skipping with it will not fall off. Of course, there is no problem in the shopping scene. < / P > < p > the air is vibrated by the diaphragm of the moving coil or the armature of the moving iron, and then the vibration is transmitted to the eardrum through the air, which is the working process of most earphones. < p > < p > bone conduction headphones jump out of this way of thinking, directly rely on the vibration of the skin and bone, the vibration is transmitted to the eardrum. The advantage is that no matter how noisy the outside world is, you can “hear” the sound, especially in places like airplanes and subways. Because of different working principles, it is even more efficient than active noise reduction earphones. Of course, there are also defects in this way of transmission. Its sound quality will be different from that of conventional headphones, and the low-frequency effect of open structure can be ignored. < / P > < p > like its predecessors, openmove still builds a sound field with a clear and accurate location. The positioning is quite accurate. Although the sound field is not large, it does not feel cramped. And this generation is more popular than as800. If you try Lin Zhixuan’s live at the intersection of phoenix flowers, you can see that the first part of singing is very crisp, which is not inferior to the real wireless headphones at the same price. However, because your ears can still hear sound at this time, its listening feeling is weaker than that of conventional headphones in noisy environment. < / P > < p > in addition, openmove also has optimization for the leakage of bone conduction earphones, and the situation that everyone can hear clearly next to the loud voice has been greatly reduced. But the principle of this kind of earphone is different from that of traditional earphones. If the music is loud, the people next to them will still hear if there is no sound, although it is difficult to hear clearly. < / P > < p > as a consumer headset, another goal is to call. Shaoyin considers the location and orientation of electret microphone and the design of acoustic cavity to achieve the optimal noise reduction effect. What is considered here is that making a phone call in the subway can also clearly test the requirements. < / P > < p > in addition to sound quality, openmove also has connectivity. Openmove uses a high-throughput qcc3024 Bluetooth chip and can connect two devices at the same time – which is a good thing for young people who generally own multiple mobile phones. < / P > < p > with these details added, openmove has become more grounded while retaining the main features of the previous bone conduction headset (it can also hear external sounds). This is also reflected in the price. Compared with the previous price of thousands, the price of 598 yuan seems to be more people-friendly. < / P > < p > for the bone conduction category, it is a change in positioning. Its use scene has gradually changed from long-distance running to doing drama on the subway, chatting with acquaintances, or shopping and listening to songs in daily life – from professional products to “amateur” products.
