Tuning Adjustable Dual-Driver IEM

Challenging all flagship products in the HIFI industry with its formidable strength

Harman Target Version

Built upon the acclaimed Harman FR curve within the HIFI community, and pushing beyond its boundaries!

In the past two years, many audiophiles have been pursuing 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 involved 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.
