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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size:26px;font-family:arial, helvetica, sans-serif\"\u003e KZ-Castor breaks through traditional acoustic tuning methods by innovatively adopting a dual-dynamic driver acoustic design.

(Why do so-called HIFI earphoneproductshave less drop in the low frequencies? This is done to create a false sense of perception for users. By reducing the low frequencies they aim to make the mid and high frequencies seem better, claiming it's for low distortion. In reality, this is all deception, as they can't technically enhance only the 100Hz frequency range without affecting other ranges.) This meager drop in low frequencies is like reducing the explosion of a nuclear bomb to the sound of a firecracker.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch1 style=\"text-align:justify\" class=\"MsoNormal\" align=\"justify\"\u003e\n\u003cspan style=\"font-size:28px;font-family:arial, helvetica, sans-serif\"\u003e In contrast, Castor boasts a drop of over 10dB in the 40Hz-300Hz range.

The primary limitation here is that it's nearly impossible to boost only the 20-200Hz range without affecting the 300Hz range; excessive boosting in the 300Hz range leads to muddiness in the sound. However, with our Castor's dual-driver design, one driver is dedicated to independently handling the 20-200Hz frequency range and fully amplifying the output within this range.
