Temeprament Technelegy Black Bell
earbuds come standard with three layers of earbuds in the mid-range price range. They also feature a Litz-structured, genuine silver-plated cable. Their 15mm large dynamic driver is completely independently developed and produced, and is handcrafted. The lightweight metal housing boasts state-of-the-art hardware craftsmanship, weighing only 2.6 grams. The standard Kaisheng modular system allows for unlimited expansion. Kaisheng's patented ergonomic housing, designed with true big data sampling, boasts a comfortable fit that has been market-proven for six years. The short-line design allows for both standard and around-the-ear wear, similar to popular in-ear earbuds. The competitive advantage of these earbuds lies in the fact that Yinkang, a leading domestic tuning team, has repeatedly awarded numerous awards for its derivative product designs. While the Black Bell earbuds are positioned as Kaisheng's entry-level product, they are still incredibly powerful compared to other earbuds.

Product Details
The diaphragm of the BELL-LB unit is thesame as the first generation of the flagshipproduct, the first generation of the black bell.The black bell S is equipped with the same collmaterial as the first generation of the titanium bell,which brings more outstanding details and dynamics.
The further optimized flagship internal magnetic circuit structure keeps the relative clearance between the coil and the magnet within 0.4mm. This precise structure delivers Tesla-level magnetic density and improved dynamic transient response.

The earphones' rear shell is crafted from aircraft-grade 6-series aluminum-magnesium alloy using a high-precision automatic lathe and 5-axis CNC machining process. The surface is then hand-brushed and polished. The thin, lightweight shell weighs only 2.6 grams, making it suitable for extended wear.
The three-layer Iitz-structured, genuine silver-plated (thick silver) cable, developed over three years, is crafted to the highest standards for advanced cables. The detachable head is self-spinning and utilizes Kaisheng Technology's patented modular system. This significantly enhances sound quality, functionality, and expandability.
