KZ ZST Hybrid Driver Earphones Earphones no 1BA+1DD High-Performance In-Ear (Purple, microphone)

---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- [Amazingly High Performance] ・These are hybrid in-ear headphones featuring a balanced armature (BA) driver and a dynamic (DD) driver. ・The highly fitted eartips reduce external noise. ・The dynamic driver, which handles the low frequencies, and the balanced armature driver, which handles the mid-to-high frequencies, are both fully utilized. The excellent resolution, separation, and powerful bass are unique to this hybrid type. The sound of hi-hats and crash cymbals, in particular, sounds outstanding with these headphones. ・These headphones offer exceptional value for money and are definitely recommended. There are no other headphones in the same price range at electronics retailers that can compare to the ZST. The sound quality is comparable to, if not better than, headphones from well-known Japanese manufacturers that cost several times more. [Achieves its full potential through burn-in] After 100-200 hours of burn-in, the sound quality will evolve to an astonishing level, completely different from when you first purchased it. The frequency range will widen, and the extension of bass and treble will improve. The balance of the frequency range will be flat, and the localization and sense of distance of vocals will be superb. The soundstage will become wider, and you will feel a greater sense of presence. For comparison, when I re-cabled the same hybrid in-ear headphones with the original cable I normally use, the ZST seemed to produce a cleaner midrange, high frequencies, and soundstage. [When using the KZ ZST Upgrade Cable (sold separately)...] Compared to the included cable, the sound becomes clearer and more defined. It's a soft, easy-to-handle cable with meticulous craftsmanship and a beautiful design.
