R&D Capability

With excellent hardware and software technology, AngelPods Pro series, a luxury brand in the field of technology, has created the world's smallest OWS. This breakthrough is thanks to Yingdi's independently developed titanium alloy bidirectional rotating hinge, which has a maximum opening angle of 150 degrees, high strength, good stability, and small size, with a uniform wall thickness of 0.4mm and the thinnest part reaching 0.15mm. Yingdi adopts aviation grade titanium alloy 3D printing technology, undergoes ultra-high temperature melting at 1600 ° C, uses inert gas with a purity of nearly 99% to atomize liquid titanium alloy into micrometer sized particles, and then uses 1600 ° C hot laser precision printing to form. This complex process reduces the overall thickness of the bidirectional rotating hinge by 30% while increasing its stiffness by 36%, further enhancing its durability and sturdiness. Its small size makes it very convenient for users to carry and move around! The earphone shell is made of skin friendly polyurethane two-color integrated injection molding, which is very comfortable to wear with a combination of soft and hard. The earphone battery has a super long battery life of 6 hours; The lower shell of the charging compartment is formed by forging aviation aluminum, which is then processed by CNC3D cutting, polishing, grinding/sandblasting, and then oxidized. Finally, it is finished with a high-speed engraving machine for high gloss. The process of the charging compartment surface shell is particularly complex. After forging and CNC processing, the charging compartment surface shell is injected into the mold, and the plastic and hardware are seamlessly joined. After polishing, sandblasting, oxidation, and high gloss, the manufacturing process is precise and complex. When the charging compartment is opened, it looks like the wings of an angel unfolding, showing its artistic, noble, and luxurious quality! The charging compartment is equipped with 500mah2C fast charging, which can be fully charged within 50 minutes and has a comprehensive range of over 40 hours!

Excellent hardware and software technology, creating a luxury brand in the field of technology! Angelpodspro adopts imported high-quality unit 1811 (biological diaphragm+nano coating) like a sound painter, and the precisely tuned cavity structure is like a professional acoustic laboratory, jointly ensuring the purity of the sound transmission path Acoustic engineers need hundreds of hours of repeated fine-tuning to find the right point that allows all frequency bands to coexist harmoniously. Wearing headphones is like sitting in the 10th row of a concert hall, where you can clearly distinguish the position of the left rear cello group and the right front flute. In game scenes, the accuracy of determining the distance and orientation of footsteps is so precise that it creates a superpower illusion of sound recognition!


The three frequencies of the headphones are harmonious like a color palette

Bass: The texture of hitting a sandbag with a boxer's kit - deep and powerful without banging the head, and the vibration of the air can be felt when diving with drum beats instead of the murky buzzing

Midrange: The voice is like pouring out face to face, whether it's the smoky and grainy notes of jazz female vocals or the lip and tooth sounds of folk singers, they are all truly tangible

High note: The crystal wind chime like translucent extension ensures that the high position of the violin does not turn into a harsh scraping sound, always maintaining a silky smooth and pleasing to the ear The dynamic sound field of "air feeling" makes sports and sound more immersive ..!
