As the owner of the headset for about two months, I have the following to say:

Incredible build quality and material appearance, from the fabric cushions to the aluminum, etc.
Amazing sound with a wide range of volume without losing quality.

Very good customization program for the equalizer characteristics of the headphones, allowing you to take their capabilities to the infinite. You can create your own profiles for each genre of music or game type by finding some on the internet or use the ready-made profiles that already exist. It also has a menu to change the color, brightness, or mode of the LED, or to activate certain functions of the built-in processor of the headphones, such as enabling the 7.1 surround sound and others.

The pulsation function thanks to the 5cm coil that creates vibrations in the head! It's really impressive, especially for powerful bass in hip hop songs or explosions in movies and gaming.

Perhaps the only downside I found is that the functions and special profiles can only be activated and remain active on a computer where the program is installed.
If someone needs them for a console like me with a PS4, they will simply default to a setting that is perfectly satisfactory and much better in performance and sound quality than other high-end headsets in the range of 80-100 euros (comparatively).

(I bought them for 150 euros, so at a lower price, you can go for them with closed eyes)

Sorry if I rambled on, I hope I helped and covered everything. :)
