Thank you for replying. Are you saying that the dt880 250 ohm Chrome edition only looks different from the normal version of dt880 250 ohm without sound tuning? (Unlike dt880 black edition)
(Actually, I already use dt770pro 80 ohm for gaming, but this have so many bass. So I want to buy less bass model of dt880)
Correct, chrome and the original are the same headphone. It’s purely aesthetic. Only “Beyerdynamic DT 880 Special Edition Black 250 ohm” has the other tuning. All other variations have the original tuning without the bass.
Thank you very much for your help 
Damn. The manufaktur edition looks nice imo. I like the blue accent. Sucks it’s only eu only through custom order.
