DoNews, March 8 (Ding Fan) Today, Honor Smart Life held the annual flagship new headset Earbuds 3 Pro media tasting meeting in Beijing. After the Honor Earths 3 Pro and the flagship mobile phone Honor Magic4 series were unveiled together at the 2022MWC on February 28, they attracted the attention of many people inside and outside the industry with the world's three premiere technologies. Honor Earthbuds 3 Pro is the world's first coaxial dual unit with a large amplitude dynamic and ceramic tweeter, the world's first TWS headset that supports temperature measurement, and the world's first TWS headset that supports 5C fast charging technology.
Use scientific interpretation of metaphysics, based on the core demands of users to create good sound quality
As a headset, the most important core element is sound quality. In honor's view, to create good sound quality, we must first determine the sound unit. Therefore, Honor has been committed to bringing users a good sound quality that is subjectively comfortable to listen to, and after many design demonstrations, it finally chose a new 11mm ultra-large amplitude dynamic coil and ceramic tweeter dual-unit TWS hardware solution. The 11mm ultra-large amplitude dynamic unit can achieve a 0.6mm ultra-large amplitude to ensure the sufficient power of the low frequencies in the headphones, bringing a magnificent atmosphere and a shocking bass performance, and also selecting the ceramic tweeter that only appears in Hi-Fi wired headphones to compensate for the high-frequency performance. The ceramic unit is a new star in the headphone industry in recent years, and its sound principle is directly driven by voltage, so the response speed is faster, bringing more transparent and clear treble, which is a good partner for the dynamic unit.
Excellent sound quality requires not only excellent hardware, but also suitable sound tuning. In terms of tuning, different manufacturers have different stylistic tendencies for tuning, in the glory of the view, good sound quality needs to have excellent restoration ability, minimize sound dyeing, restore the emotions conveyed by music producers and singers through songs; good sound quality should be in line with the user's auditory psychology, through fine debugging of different frequency bands, find a sound quality style that meets most of the user's listening.
Therefore, through thousands of times of balanced debugging, optimization and polishing with industry big coffee and audition evaluation of hundreds of users, Glory R&D has finally formed a sound quality effect with good balance of high, medium and low frequencies, excellent reduction ability, and in line with the listening habits of most users. Many people say that headphones are metaphysics, but in fact, Glory uses science to explain metaphysics, and finally creates the Glory Earbuds 3 Pro, which brings a solid and powerful mid-bass, bright and clear effect of high notes, and achieves excellent sound quality performance.
People are moving, the scene is changing, noise reduction should also be intelligent, daily users will be in a variety of different environments, in order to reduce the impact of noise on user listening, Glory Earbuds 3 Pro brings the "scene wisdom noise reduction" function, according to the user's different noisy environment conditions, intelligent adjustment of light noise reduction, moderate noise reduction, deep noise reduction mode, noise reduction depth up to 46dB. For example, in relatively quiet places such as libraries and offices, the Honor Earbuds 3 Pro can switch to a 20dB+ light noise reduction mode to reduce noise interference such as keyboard typing. In everyday environments such as cafes and pedestrian streets, headphones will be adapted to a moderate noise reduction mode of 30dB+. If you are in a high-noise scene such as subway and airplane, the Honor Earths 3 Pro can achieve a maximum depth of noise reduction of 46dB.
Since the ear shape and ear canal structure of different users are diverse, the noise reduction effect will vary. Based on the collection data of hundreds of users' real ear canals, Honor R&D carries out personalized effect design under different ear canal characteristics, and adds personalized ear canal parameter adaptation technology in adaptive leakage compensation and earbud detection mode, so that different users can enjoy better noise reduction effects as much as possible in different wearing states.
For the wind noise scene where noise-canceling headphones are difficult to break through, Honor Research and Development has also carried out many analog tuning. The Honor Earths 3 Pro has two microphones to identify wind noise and intelligently adjust external noise monitoring strategies for better active noise reduction adaptation. In view of the problem of "plugging effect" of in-ear headphones, in the design of Honor Earbuds 3 Pro, the VPU bone sensor picks up bone conduction characteristics and the full-link AI call noise reduction optimization, and the overall removal of the ear plugging effect has reached the industry's advanced level, bringing users a dialogue experience close to "no sense of wearing".
With the rapid development of new technologies and models related to great health, the concept of national health has also entered a new stage of rapid popularization, and the health awareness of global consumers has been raised to a new height of awareness. Honor Earths 3 Pro is the world's first TWS headset to support temperature measurement, in order to achieve this function, Honor audio R & D team has also undergone a complex research and development process. Due to the small size of TWS headphones, while ensuring light and comfortable wearing, it is also necessary to balance all the components such as temperature measurement modules and sound units, which puts forward more extreme requirements for the overall spatial structure design of the product. After repeated demonstrations in research and development, the challenge to the ultimate space layout was finally completed.
At the same time, in order to ensure the accuracy of temperature measurement, the Honor R&D team and medical experts and sports health experts summarized the research on core temperature monitoring at home and abroad, and found that the temperature of the ear canal eardrum has the highest correlation with the real core temperature of the human body. Honor R&D engineers innovatively introduced the "core body temperature fitting" algorithm, the temperature of the eardrum as a substitute for the core temperature and algorithm training, the temperature value read out by the sensor is associated with the relevant data of the ear canal model to establish a model, and the temperature of the eardrum is derived from the temperature of the outer skin of the ear cavity, and then the core temperature is calculated.
Honor Earthbuds 3 Pro put three contact sensors in each left and right headphones, which not only makes the temperature measurement process more secure, but also makes the temperature measurement data more accurate, and finally realizes that the temperature error of the Honor Earthbuds 3 Pro is only ±0.3 °C (the temperature difference between the temperature gun used daily is about ±0.2 °C). When the user wears the headset, it will automatically open the real-time temperature monitoring, support single and periodic temperature measurement, and can also form a cycle body temperature change curve according to the temperature measurement data, help users manage body temperature health anytime and anywhere, activate the user's continuous temperature measurement needs, and achieve the purpose of science and technology to help health management.
For TWS headset products, convenient and efficient fast charging is a pain point for users. In terms of improving the idea of fast charging, the Honor R&D team has chosen another way to find potential in the "charging speed", and "inherits" the already mature fast charging technology on the mobile phone tablet to the TWS headset, bringing users a convenient experience of charging with and using. Honor Earths 3 Pro became the world's first TWS headset to support 5C fast charging technology, only 5 minutes of charging, you can listen to songs for 2 hours, can meet the user's daily temporary outing and other emergency scenarios. In the state of the charging case, the Honor Emeralds 3 Pro can achieve 24-hour music battery life.
Audio is one of the core carriers of Honor's accelerated "1+8+N" all-scenario strategy, and at this stage, Honor has rich technology accumulation and strong underlying research and development capabilities in the audio field. In the future, Honor Audio will achieve differentiated development in industry-leading basic experiences such as audio experience, health care, and AI interactive control. While the wisdom integration ecology continues to show its unique advantages, it will also continue to break the four boundaries of category, bottom layer, ecology and scene, leading breakthroughs and innovations in the audio field, and driving consumer experience and wisdom upgrading.
Honor Earths 3 Pro is a true wireless headset of Honor positioning the annual sound quality flagship, which is a TWS product that provides users with a comprehensive experience of surging sound quality, smart noise reduction, health management, and smart connectivity. The product is priced at 199 euros worldwide, and has been opened for reservations on major e-commerce platforms officially authorized by Honor, and interested users can pay attention to reservations. Regarding the other surprises of the Honor Earths 3 Pro, we may wish to look forward to the upcoming new product launch on March 17.
