Based on the Harman graph, this performance parameter outperforms other dynamic driver units. Based on incredible pure and natural sound quality, impressive acoustic structure design, and acoustic spatial algorithm simulations, Polaris' acoustic structure is designed to avoid unnecessary resonances, resulting in purer, more natural sound than ever before. High-grade metal shell & professional cable with more texture than the picture.The high-density alloy material is formed and through the process of engraving, molding, polishing, and polishing, it has a smooth and delicate texture, expressing the texture of high-grade mirror-like metal. Unique, innovative and original design appearance is unforgettable. Flat Transparent Black Cable for Superior Sound Quality, Due to its low impedance, the flat transparent black cable can significantly outperform regular OFC (Oxygen Free Copper) IEM cables and improve the overall sound quality of your IEMs. Equipped with professional adjustable frequency filter. Satisfies all demands for sound quality. Polaris is equipped with a professional adjustable frequency filter that supports 4-step sound frequency intensity adjustment, allowing more than a dozen sound styles. This allows you to precisely customize bass and treble frequencies, giving you a completely different and more professional experience than traditional earphones. Note: The above switch adjustment mode is the recommended mode that is suitable for most users. Users can customize the switch mode themselves according to their preferences. Polaris uses Harman graphs, popular with industry professional audio enthusiasts, as a reference tuning standard, achieving a degree of consistency that far exceeds similar competitive products. Harman graphs represent theoretical target acoustic characteristics based on data collected and analyzed from detailed studies of different countries, different age groups, and different human ear canal structures. It most encapsulates the sound quality preferred by the majority of listeners, is known for its natural tonal balance, and is widely loved by music lovers. As a result, this has become a desired goal for many audio brands. Meeting the Harman graph in earphone acoustics is a highly complex acoustic engineering endeavor, and products pursuing this goal in the hi-fi industry are typically expensive. Now, through Polaris, you can experience an unprecedented level of "natural" sound quality defined by the Harman graph.
