An Entry-Level Headset with Great Cost-Effectiveness

KZ, an eminent manufacturer of professional aural transducers, has recently launched a new offering - the KZ EDXS - which boasts an array of impressive attributes. In assessing this product, it is prudent to consider its modest price of merely $13 in order to remain objective.



Aesthetically Pleasing and Anatomically Comforting Design

The KZ EDXS exhibits a distinctive three-dimensional metallic facade that enhances its depth, while the asymmetric silhouette and reflective surface texture of the mirror-polished metal create a striking interplay of luminosity and shadow when viewed from diverse angles. The malleable auricular attachments are ergonomically contoured to nestle comfortably around the pinna, and the dermatologically inert silicone tips (available in three sizes: large, median, and small) aid in improving stability and overall comfort. Moreover, once securely positioned, the EDXS can effectively attenuate ambient noise, facilitating an immersive aural experience.



High-Performance 10mm Dynamic Driver

Equipped with a 10mm composite diaphragm dynamic transducer, the EDXS delivers a powerful and impactful bass performance. The unalloyed copper coils in the dynamic transducer enable a high resolution and excellent fidelity in the midrange and treble frequencies, ensuring the accurate reproduction of vocals and music. Tuned by professional acoustic engineers for high-definition sonic quality, the EDXS exhibits a frequency response curve that accounts for the perceptual attributes of the human auditory system to guarantee balanced and natural acoustic performance across the complete spectrum, while also proffering exceptional clarity and detail.



2pin Gold-Plated Connector, Silver-Plated Wire Core and High-Definition Microphone

The KZ EDXS is equipped with a 2-pin universal gold-plated connector, enabling effortless upgrades to alternative earbud cables. It is accompanied by a high-purity silver-plated flat cable, incorporating a high-precision silver-plated core that bolsters signal transmission and facilitates superior resolution and conductivity of audio signals, ultimately resulting in the transmission of high-fidelity sound. The EDXS's high-definition microphone, featuring one-button control, supports call and music toggling for a more convenient, hands-free auditory experience.
