{"type":"firestarter.listing","listing":{"id":"lst_Z4Yyqret","product_name":"KZ Vibe X","category":"In-Ear Monitors","description":"                                          13mm Self-developed Ultra-Low Frequency Vibration Driver                This independent acoustic unit features deep low-frequency extension and strong dynamic response. It delivers steady, natural bass vibration within the eardrum, with tight, quick bass bursts and no extra reverberation. You get full, layered bass that stays clean and non-muddy, making EDM, game sound effects and movie soundtracks more immersive and enjoyable even on low-power devices.                                                                                Zenith Flagship-Grade 10mm Dynamic Driver                Adopted from KZ Zenith flagship model, this driver has a high-performance magnet system and ultra-narrow sound route for high resolution and fast transients. It keeps vocals clear and instrument details intact, with an open, natural soundstage. Heavy bass will not mask mid-high frequencies, giving you balanced, smooth and realistic sound for all kinds of music.                                                                                3D Tactile Bass &amp; Independent Frequency Division                It upgrades traditional 2D flat bass to 3D immersive tactile bass. The independent physical frequency division structure separates ultra-low bass and mid-high sounds, preventing bass from masking vocals or narrowing soundstage. This design solves the muddy midrange issue of common heavy-bass IEMs, keeping powerful bass and clear vocal details at the same time.                                                                                180° Wide Open Soundstage                Precise dual-driver acoustic assembly breaks the narrow, closed soundstage of regular IEMs. It improves overall sound detail and vocal clarity, presenting a natural 180° wide soundstage. Instruments and vocals have accurate positioning and clear layers, offering a lifelike, immersive listening experience for music, gaming and movies.
