LINSOUL KZ Castor Tunable Dual Driver Earphones Its strength challenges all flagship products in the HIFI industry design 3D printed shell Closed type

Castor features a unique design with two stacked dynamic drivers. One driver is responsible for bass output in the 20-200Hz frequency band, and the other driver is for mids and trebles. Through electronic crossover technology, these two drivers work together without interference in each frequency band. This allows Castor to deliver powerful, energetic bass and stunning mids and treble. (𝐇𝐚𝐫𝐦𝐚𝐧 𝐓𝐚𝐫𝐠𝐞𝐭 𝐕𝐞𝐫𝐬𝐢𝐨𝐧) Built on and beyond the boundaries of the highly regarded Harman FR curve within the HIFI community! Over the past two years, many audiophiles have sought greater adherence to the Harman FR curve. Many brands launch their flagship products with reference to the Herman curve. Due to the high degree of difficulty involved in acoustic tuning to achieve the Herman curve, many brands only fine-tune their flagship products to a relatively high degree of compliance. 𝐇𝐚𝐫𝐦𝐚𝐧 𝐓𝐚𝐫𝐠𝐞𝐭 𝐰𝐢𝐭𝐡 𝐈𝐦𝐩𝐫𝐨𝐯𝐞𝐝 𝐁𝐚𝐬𝐬 𝐕𝐞𝐫𝐬𝐢𝐨𝐧 Traditional earphone products typically exhibit around 6-7dB reduction in the 40-300Hz frequency range, and some earphone products marketed as HIFI can reach as low as 45dB. (Why do so-called HIFI earphone products degrade at low frequencies? This is to create a false perception for users. By reducing low frequencies, they claim to improve mid-high frequencies and reduce distortion. In reality, this is all a deception and will affect other bands as they cannot technically enhance only the 100Hz frequency band.) ♘😈 Built-in professional filter, supports bass and treble adjustment ♝💘Castor is equipped with a professional acoustic filter that supports 2-step adjustment for bass and 2-step adjustment for treble. Users can fine-tune their sonic preferences to create 16 different audio profiles based on their musical preferences. Vertical stacked cavity structure To balance sound quality and wearing comfort, Castor adopts a vertically stacked cavity design, which reduces the overall earphone size and improves the comfort when wearing. The integrated injection molding process is theoretically more than 10 times more precise than traditional 3D printing technology. Traditional 3D printing has a tolerance of about 0.1mm, whereas Castor's internal support structure has an accuracy of about 0.01mm. Castor uses premium memory foam ear tips with a suitable physical structure that significantly reduces teeth grinding noise.
