Hidizs MD4 review

Hidizs MD4

There is no doubt that Hidizs (the well-known audio brand founded in 2009 by Tamson) follows a straight and determined path. It became famous for pursuing the best quality/price ratio in its DAPS, seeking as an absolute premise, the best sound, thanks to its professional audiophiles in its R&D department. After a few years and with several models under their belt, they thought of creating IEMS as well. Until the present day, this progressive development has led them to present the model that I am now going to analyze. It is the Hidizs MD4. As you can see from its name, it is an IEMS with 4 BA drivers designed and customized by the brand itself. They have a double switch to select 4 different tunings and a 3-way frequency divider. The body is made of multi-metal. It has a high-precision 3D printed straight acoustic sound tube. It is fitted with a high-quality 4-strand cable with silver and OFC wires on a 2Pin 0.78mm gold-plated connection. It is available in 3 beautiful colors, black, white and indigo. Its outer face exhibits a marbled pattern to match the body color. Naturally, Hidizs accompanies the set with careful staging, packaging, and quality accessories to elevate the premium feel of the product. Let’s take a look at the rest of the qualities of this great product.


First, I should comment that the color of the reviewed model is black. The box matches this color and is an almost cubic package, which on its upper side shows a realistic photo of the capsules, with the cable in place. Its dimensions are 125x125x92mm. In the upper left corner is the Hidizs logo inscribed in gold. At the bottom, left is the model name and a short description. At the bottom right is the Hi-Res Audio logo. On the back side, there are two columns: the left column is written in Chinese, and the right column is in English. You can read the specifications, the contents of the box, a schematic with the position of the switches and their corresponding frequency responses, and the brand’s markings.
When the box is opened, the capsules are encased in a dense, black foam mold, lined with a dark cardboard cover with the model name and a slogan inscribed in gold lettering on the bottom. Once this first layer is removed, there is another mold containing three sets of silicone tips and a tool for cleaning and moving the switches. The third layer consists of a square box, with rounded corners, made of brown leather, on the top of which is the brand’s seal. The complete contents are as follows:

  • 2 MD4 capsules.
  • 1 x 2Pin 0.78mm cable and 3.5mm SE plug.
  • 1 brown leather carrying case.
  • 3 pairs of white silicone tips, with vocal enhancement.
  • 3 pairs of black silicone tips, with bass boost.
  • 3 pairs of white silicone tips with black core, balanced.
  • 1 cleaning brush.
  • 1 user manual.
  • 1 warranty card.
  • 1 explanatory card with the modes of the switches and their FR.

What I like about Hidizs is that they design a compact packaging with great content, a high quality, and a very attractive box, as well as 3 pairs of silicone tips, which allow you to fine-tune the sound of the MD4 even more. I can only miss some silicone tips, to be very strict.
