Comparable à ce qui se fait à prix équivalent.
Overall, the unit holds up quite well against closed-back models in the $400 to $500 range I’ve listened to from Grado, Bowers & Wilkins, and Audeze.

La membrane est possiblement une lamination de graphene avec autre chose. Je ne crois pas qu'il existe encore une technologie pour produire des membranes 100% graphene. La membrane utilisée est probablement un composite quelconque. Beaucoup de bla bla et aucune données pertinente. Typical audiophile noise.
Graphene is typically added, in the form of nano-particles, to existing composite materials or substituted for existing ingredients. As an example, in volumes of 1% or less, it can be added to an existing polymer to add strength as well as function. Sports equipment maker Head, for example, adds graphene to the stems of its tennis rackets to reduce weight and add strength. Bicycle tire manufacturer Vittoria and Italian graphene manufacturer Directa Plus include graphene in its high-performance tires.
