In the past two years, many audiophiles have pursued a higher degree of adherence to the Harman FR curve. Many brands have used the Harman curve as a reference to launch their flagship products. Due to the challenging nature of acoustic tuning in achieving the Harman curve, many brands only fine-tune their flagship products to a relatively high degree of adherence. On the other hand, some lower-priced products, constrained by technology and cost, do not follow the Harman curve style in their tuning.

KZ Castor breaks through traditional acoustic tuning methods by innovatively adopting a dual-dynamic driver acoustic design. This approach has resulted in the perfect Harman curve that outperforms flagship products from other brands.
