Spet sem slišal glasbo, priključeno na mobilnik: zakaj 30 evrov z žico zveni bolje kot 150 brez nje

A Spanish consumer has returned to enjoying music through wired headphones after discovering that a pair costing just €29.29 offers superior sound quality compared to more expensive wireless alternatives. The product in question is the KZ ZSX, which is available on AliExpress at a significantly reduced price. Unlike typical budget earphones, these wired models feature advanced audio technology that delivers clearer bass and better vocal separation, making them stand out in their price range. The KZ ZSX model includes six transducers per ear, with each headphone housing one dynamic driver and five balanced armature units. This configuration allows for a more detailed and layered listening experience. The dynamic driver handles low frequencies, while the five balanced armatures divide mid and high frequencies, ensuring that deep bass does not overpower vocals or other elements in complex tracks. This design results in a richer, more immersive sound that distinguishes the ZSX from standard entry-level earphones. In comparison to the popular KZ ZS10 Pro, which uses four balanced armature drivers per side, the ZSX offers an additional unit, enhancing clarity and depth. While the ZS10 Pro remains a top-selling model, the ZSX provides a noticeable improvement in sound quality without requiring external amplification or conversion devices. Its sensitivity rating of 114 dB and impedance of 24 Ω make it suitable for daily use directly connected to a smartphone. One of the key advantages of the ZSX is its wired connection, which eliminates the need for Bluetooth pairing, software updates, or battery maintenance. This simplicity ensures consistent performance over time, avoiding common issues associated with wireless earbuds such as connectivity drops or degraded sound quality due to aging batteries. The included two-pin connector also makes repairs easier, as damaged cables can be replaced without discarding the entire set. The ZSX comes in four color options, black, blue, and cyan, with two variants featuring a built-in microphone, volume control, and call buttons integrated into the cable. These features enhance usability, particularly for users who frequently take calls on the go. If a preferred finish is unavailable, the KZ ZS10 Pro serves as a close alternative, offering similar functionality with one fewer balanced armature per side. This configuration addresses a long-standing challenge in the entry-level audio market: balancing rich bass with clear vocals. The ZSX achieves both, often at a lower cost than competing models. Consumers seeking value for money and improved audio fidelity are finding that investing in a wired option like the ZSX can deliver a more satisfying listening experience without the complications of wireless technology.
