KZ Castor Wired In-Ear Monitor Earphones with Bass Reinforcement (No Microphone, Silver)

[Harman Target Version and Bass-Enhanced Version] Tuned to the Harman FR curve, these earphones surpass many flagship products from other brands in terms of parameter performance and sonic sensation. Based on the Harman FR curve, they enhance low-frequency sensitivity and dynamic performance, delivering an overwhelming low-frequency experience. At the same time, the mid- and high-frequency ranges are seamlessly aligned with the Harman FR curve. The Bass-Enhanced Version further enhances low frequencies based on the Harman FR curve. While conventional earphones experience a drop of around 6-7dB in the 40-300Hz frequency range, KZ-Castor achieves a drop of more than 10dB in the 40-300Hz range, demonstrating far superior low-frequency performance. [Powerful Dual Driver Structure] KZ-Castor features an innovative laminated dual dynamic driver structure design. One driver handles bass output, covering frequencies around 20-200Hz, while the other handles mid- and high-frequency ranges. Precision electronic crossover technology allows these two drivers to work together without interference, delivering powerful, energetic bass and impressive mid- and high-frequency ranges. Equipped with a 10mm dual-magnet dynamic driver and an 8mm dynamic driver. Built-in professional filters allow for adjustable low and high frequencies. Castor is equipped with a professional acoustic filter, allowing for two-stage adjustment of low frequencies and two-stage adjustment of high frequencies.

[Top and Bottom Stacked Cavity Structure] To balance sound quality and comfortable fit, Castor uses a top and bottom stacked cavity design, which reduces the overall earphone size and improves wearing comfort.
