The KZ ZES enters the Hi-Fi scene as a 'black horse,' utilizing a sophisticated hybrid architecture to bridge the gap between raw power and intricate detail. By combining a 12mm super dynamic driver for mid and low frequencies with a 6.8mm electrostatic speaker for high and ultra-high frequencies, these earphones provide a more robust stereo sound and a wider sound field than standard dynamic units. Performance is centered around the 'Super Unit' 12mm driver, which is engineered to surpass most dynamic units on the market by offering more substantial output power and fuller bass. The addition of the electrostatic unit ensures superior high-frequency sensitivity, creating an immersive atmosphere with profound and ethereal sound effects that allow for a deeper interpretation of musical details. Design and build quality are highlighted by an embedded metal-plastic connection process and wear-resistant metal decorative parts. The earphones are paired with a premium 8-strand, 200-core high-purity silver-plated wire, which minimizes external interference and ensures stable electrical conductivity for high-quality audio transmission. For the modern user, the KZ ZES includes a condenser microphone for convenient operation, compatible with both iOS and Android systems. The 0.75mm gold-plated pins ensure the earphones are compatible with 99% of 2-pin upgrade cables on the market, offering users a personalized and upgradeable audio experience. Offering a professional frequency response of 20-40000Hz, the KZ ZES is an ideal choice for listeners who demand a balance of powerful bass and precise high-end clarity without compromising on build durability.
