So the hd 681 

copy the presonus HM7

The 668b 

copy the samson smr 850

But the 681 EVO ? I have no idea
I was just curious about this.
I have the hd 681 and I am going to buy both the 668B and the 681 EVO for 30 euros a piece because I feel they are ABSOLUTELY worth it that price and each headphones has a diff sound signature.

They are all copies of the basic design of the chassis of the AKG K240

 

[ubs28]

Yeah, they are clear AKG K240 rip offs.

I don't think evo's are a copy of any headphones. Superlux has not copied samson and presonus, it is the opposite. Those are rebranded superlux headphones. But those hd681/668b are indeed obvious akg copy. On other superlux models hd330/hd660 is copy of beyerdynamic dt770/dt880/dt990 and hd562 is a copy of sennheiser hd25.
