Graphene diaphragm chinese iems. I'm quite interested in the applications of this new material in headphones. It's thin, strong, and has very good electrical conductivity. Well, all the following iems are actually using graphene Coated diaphragms. Nevertheless, it's fun to see how it goes.
Single graphene Coated dynamic diaphragm:
**** PT15: $8, 15mm driver, 32 ohm. The first one.
Fiio F3: $25, 11mm driver, 40 ohm. A review says F3's graphene diaphragm is just 0.335nm thickness. That's wrong. 0.335nm is the thinnest thickness that a graphene fabric can go, in a lab.
UiiSii Hi820: $19, 10mm driver, 32 ohm. Tons of bass.
I prefer PT15>=F3>Hi820. PT15 wins in soundstage and the music genres I like. F3 wins in pop music.
Some hybrid iems with graphene diaphragm. I don't own any of them.
Xiaomi Hybrid Pro: 2 graphene DD + BA
MaGaisi K3/K3Pro: 1 graphene DD + 2BA. Highly regarded in this thread.
**** 6in1: 1 graphene DD + 2BA
Solid graphene diaphragms would need a relatively huge amount of energy to be moved because of the material's hardness.
