Description

Hidizs MD4 - in-ear headphones with four balanced armature drivers and a 3-way crossover.

Features:

  • 4 specially designed balanced armature drivers;
  • Housing made with 3D printing;
  • 2 two-level switches for adjusting 4 different sound signatures;
  • 3-way crossover;
  • Cable composed of silver and copper wires;
  • 0.78mm 2-pin connectors for cable connection to the headphones.

4 Specially Designed Balanced Armature Drivers

One of the most important features of the Hidizs MD4 in-ear headphones is the combination of 4 proprietary armature drivers, the Hidizs Custom Balanced Armature.

One driver is responsible for reproducing high frequencies, providing high detail and a wide soundstage. This allows for the subtlest tonal changes in music to be distinguishable.

Another driver is designed for mid-range frequencies, enhancing the volume and power of the sound, resulting in textured sound and incredible vocals.

The two additional drivers for low frequencies provide double the power for rich bass, giving the listener deep lows, clear response, and rich texture.

High-Precision 3D-Printed Housing

Hidizs has put a lot of effort into designing the internal layout of all the elements in the MD4 to improve sound transmission. The high-precision 3D-printed housing allows for a clean sound output, maximizing the potential of the 4 drivers. Proper placement reduces mutual interference and sound distortion, resulting in increased sound density, reduced distortion, and harmonic resonance.

3-Way Crossover

With a decade of experience in audio tuning, Hidizs guarantees that the headphones have the best characteristics for transmitting different frequency ranges. The MD4's 3-way crossover emphasizes the beauty of sound across the spectrum, highlighting highs, mids, and lows.

Adjustable Sound Signatures

The electronic crossover technology with a two-level tuning switch makes it easy to switch between four different sound signatures. This adjustment allows for adapting the headphone's frequency characteristics to any musical genre:

  • Balanced: classic Hidizs sound suitable for most listening styles;
  • Warm: open sound with more emotional character, suitable for pop music;
  • Treble: excellent highs and super highs, great for rock and electronic music;
  • Bass: enhanced bass with density and fast response, ideal for symphonic and classical music.

Elegance in Your Ears

Laser cutting, hand polishing with a beautiful amber finish. The headphone housings are polished with EU IIA certified medical resin, skin-friendly. The frame is rose gold, the faceplate is plastic, and the nozzle is aluminum alloy. Hidizs headphones combine fashionable elegance with unmatched signal purity and excellent performance in reducing harmonics and distortion.

Comfortable Wear

The angled connector for connecting the cable to the headphones is ergonomic, optimizing usability. Gold-plated materials are used in the cable connectors for stable and smooth sound transmission.

Enhanced Cable

60 strands of silver plus 60 strands of high-purity oxygen-free copper twisted tightly into a four-conductor cable ensure a beautiful appearance and excellent sound quality. Silver strands provide bright and clear sound, while copper strands add smoothness and softness to the cable.

Classic Headphone Connector

Standard 0.78mm 2-pin connectors are designed for headphone compatibility with various cables, allowing you to choose and use the ones you prefer.

Artificial Leather Case
