Authorized Dealer. The design is in the shape of a water dropletThe water droplet-shaped design features a front metal housing and a carefully crafted solid wood faceplate, with a delicate and elegant surface.Pleasant listeningModerate bass, rich mids, and delicate, but not harsh trebleClassic designWith CNC machined housing and solid wood faceplate, giving it an elegant and high-end appearance.In-Housing Developed Planar DriverDual magnetic driverThere is a dual magnetic field rectangular array structure, which has high transmission sensitivity, uniform soundstage distribution, and good transient response. It uses magnetic mechanics to reasonably match two sets of high-performance rare earth iron boron magnets, which significantly improves the efficiency compared to ordinary single magnets.Driver FrameIt is made of aviation aluminum magnesium alloy material with a CNC machining pro- cess, so the size of the sound hole and vent hole is more precise, and it can optimize the movement of the diaphragm and accurately reproduce the rhythm of each frequency point. It can effectively reduce the resonance of the sound chamber, making the sound more pure and comfortable, while also increasing the lifetime of the driver.DiaphragmIt is made of the latest self-developed ultra-thin composite material, combined with aluminum coil to make its treble more transparent and clean, while also extending the soundstage and making it wider.Pleasant SoundThe scientific combination of ultra-thin composite diaphragm and powerful magnet makes its bass punchy and elastic, while also keeping high resolution for the treble.The mid-range vocals are rich, emotional, and positioned slightly forward.Comfortable to wearThe shape of the earphones perfectly matches the contour of the ears. The material of the earbud is very soft, making it very comfortable to wear.High-end material selectionThe wood faceplate has a bright surface and good texture The faceplate is carefully selected from precious wood that has been preserved for many years and is made by CNC precise machining, as well as traditional handmade techniques, like multiple polishing, painting, and natural air drying.High-end cable0.78mm 2-pin detachable cable design.
