[Harman Target Version and Bass Enhanced Version] Harman FR curve is the tuning target, and it outperforms many flagship products from other brands, from parameter performance to sound sensation. Based on the Harman FR curve, it enhances low frequency sensitivity and dynamic performance, delivering an overwhelming low frequency experience. At the same time, mid-high frequencies are seamlessly aligned with the Harman FR curve. The bass-enhanced version is based on the Harman FR curve and further strengthens the low frequencies. Traditional earphone products have a drop of about 6 - 7dB in the frequency range of 40 - 300Hz, but KZ-Castor achieves more than 10dB of reduction in the frequency range of 40Hz - 300Hz, which is by far the best in low frequency performance. 【Strong Dual Driver Structure】Innovative laminated dual dynamic driver structure design.
