HIDIZS MP145 PRO Planar Magnetic In-Ear Monitors

Experience High-Fidelity Sound with Ocean-Inspired Precision

The HIDIZS MP145 PRO represents a major evolution in planar magnetic earphone technology. Equipped with a customized 14.5mm ultra-precision, nano-grade planar magnetic driver, this monitor is engineered to deliver pristine, high-resolution audio with unmatched speed and clarity. Featuring an upgraded symmetrical magnetic circuit and a whale-inspired bionic pressure relief design, the MP145 PRO recreates the expansive scale of a live concert while maintaining a comfortable, fatigue-free fit for hours of critical listening.

Customized 14.5mm Nano-Grade Planar Driver

At the heart of the MP145 PRO is an upgraded 14.5mm planar magnetic driver featuring a 30% increase in copper trace density on the ultra-thin diaphragm. This structural upgrade allows the driver to respond with lightning-fast transient speed, delivering tighter, more textured bass and cleaner treble resolution without the typical harshness or sibilance associated with older planar designs.

Powerful Symmetrical Magnetic Circuit

The driver is driven by an optimized magnetic circuit that produces 40% more magnetic flux than previous generations. This highly efficient system ensures that the audio signals are converted into sound with minimal distortion, offering class-leading dynamic range and a black background that lets the micro-details in your high-resolution files stand out.

Whale-Inspired Bionic Ventilation System

To eliminate the inner-ear air pressure buildup common with closed-back earphones, the MP145 PRO features hidden acoustic vents inspired by whale tail fins. This design naturally balances air pressure within the cavity, widening the overall soundstage depth and width while preventing listener fatigue during long listening sessions.

Swappable Tuning Nozzles for Personalized Sound

Every listener has a unique sound preference. The MP145 PRO includes three pairs of swappable tuning nozzles. The silver nozzles emphasize clarity and detail for classical and acoustic tracks, the red nozzles deepen the bass response for modern genres, and the rose gold nozzles offer a balanced, natural tuning for general listening.

Premium Silver-Plated Monocrystalline Copper Cable

The included modular cable is crafted from four strands of high-purity single-crystal oxygen-free copper heavily plated with pure silver. It provides low-resistance signal transmission to preserve high-frequency air. The cable comes with interchangeable 3.5mm and 4.4mm balanced plugs, ensuring instant compatibility with any professional portable source.

Frequently Asked Questions

Q: Do these planar earphones require a powerful amplifier to sound good?

A: No. With an impedance of 30 Ohms and a sensitivity of 104dB, the MP145 PRO is designed to run efficiently off portable gear. While it sounds excellent directly from a standard phone dongle, pairing it with a quality balanced portable DAC/AMP will scale up the bass control and soundstage depth even further.

Q: How does the swappable nozzle system change the sound?

A: The nozzles act as acoustic filters. The silver nozzle opens up the treble and upper-mid frequencies for maximum detail. The red nozzle tones down the brightness and enhances lower-end punch. The rose gold nozzle provides an even-handed, natural tuning that works beautifully across all genres.

Q: Are these ear pieces heavy or fatiguing to wear?

A: Despite using a robust all-metal housing, the shells are ergonomically optimized to distribute weight evenly. Weighing only 9.5 grams per side, they sit securely in the ear without sliding or creating pressure hot spots. The bionic ventilation ports also keep air pressure from building up inside the ear canal.

Q: Can I use aftermarket 2-pin cables with the MP145 PRO?

A: Yes, absolutely. The MP145 PRO uses standard 0.78mm 2-pin sockets flush-mounted onto the top of the shells. This allows you to easily swap the stock cable out for any third-party upgrade cable, Bluetooth adapter, or custom cable of your choice.
