HIDIZS MP143 Salt: A Whale-Inspired, Ocean-Friendly IEM
HIDIZS proudly introduces the MP143 Salt, an in-ear monitor inspired by the elegance of whales and crafted with eco-friendly, plastic-free packaging. Developed in partnership with Whale and Dolphin Conservation (WDC), this innovative product reflects HIDIZS’s commitment to sustainability and ocean preservation through its "ocean-friendly packaging" concept. Featuring a large 14.3mm planar magnetic driver, the MP143 Salt delivers rich, clear, and detailed sound, all within a lightweight, whale-inspired design that merges superior audio quality with unique style.
Unlock 6 Distinct Sound Styles with One Pair of HiFi IEMs
The HIDIZS MP143 Salt planar HiFi IEMs are designed with HIDIZS' innovative Pneumatic Sound Tube Technology, featuring three interchangeable pneumatic sound nozzles. This allows users to enjoy three unique sound signatures—high-frequency, balanced, and low-frequency—by adjusting the airflow direction within the earphone chamber. Tailor your listening experience by pairing each nozzle with different music genres for triple the versatility in one pair of earphones.

Low Frequency - Red: Packed with energy, suited for Rock and Heavy Metal.
Custom "FAST 2" 14.3mm Planar Magnetic Driver
The MP143 Salt features HIDIZS’s custom-designed "FAST 2" driver—a powerful 14.3mm planar magnetic unit that utilizes nano-level diaphragms to deliver superior audio information and dynamic range. Carefully tuned by HIDIZS’s acoustic lab, this driver ensures high-fidelity sound reproduction with enhanced accuracy, richness, and natural detail across all frequency ranges.
Fully Symmetrical Magnetic Circuit
The "FAST 2" driver integrates a fully symmetrical magnetic circuit, featuring a precise 7+7 N52H magnet arrangement. This setup minimizes harmonic distortion and maximizes magnetic flux up to nearly 1 Tesla, providing crystal-clear, transparent sound quality and an unparalleled listening experience.
