Material analysis
If you remove the ear pads, you can see the 50 mm neodymium drivers. The black diaphragm represents graphene, a material consisting of a single layer of carbon atoms in a hexagonal lattice structure that is increasingly revolutionizing the world of audio technology, especially in the field of headphone diaphragms. This remarkably strong and lightweight material offers some unique advantages over conventional materials previously used for headphone diaphragms.
One of the main advantages of graphene is its exceptional strength and stiffness combined with minimal density. These properties make it possible to produce extremely thin but robust diaphragms that can respond more efficiently to sound vibrations. The result is an improved sound quality, where the subtleties in high frequencies in particular can be better reproduced without compromising performance in the mid and low frequency ranges.
In addition, the flexibility of graphene helps the diaphragms to react faster and return to their original position more quickly. This results in a more precise and faster sound reproduction, which is particularly beneficial when playing complex and fast musical passages. In addition, graphene offers increased longevity for headphone diaphragms due to its thermal and chemical stability. These properties ensure that the membranes maintain their performance even after prolonged use and under different environmental conditions.
The integration of graphene into headphone diaphragms therefore represents a significant advance in audio technology. It not only offers improved sound quality, but also greater reliability and longevity, making it an attractive option for audiophiles and everyday users alike. As the development and availability of graphene progresses, this material could significantly shape the future of headphone technology.
We can also see through the grille (pictured above) of the back cover to the diaphragm, which I have not lasered for preservation reasons. However, the material of the metal grille is quite interesting, as we see a special steel that contains high levels of chromium, mangnesium and nickel in addition to iron.
The fork and the headband of the headphone suspension are made of a special aluminum-silicon alloy right up to the rotating mechanism. This material is very strong, light and easier to machine than pure aluminum.
The steel of the headband for length adjustment is coated black.
The coating is a special and flexible alloy of iron, chromium and nickel.
The rest of the shells are made of impact-resistant, matt black plastic. The mix of materials gives no cause for criticism, on the contrary, this is really high quality.
