I have the KZ HD9 in white and previously posted my impressions. (arrived in new KZ packaging like ATR) I have also ordered the QKZ DM200 in black. From appearances the DM200 and S12 from the Russian site seem to be the same as the KZ HD9. I like the HD9 so hopefully the DM200 uses the same drivers. When I receive the DM200 I will let you know if they sound the same. The HD9 are on Aliexpress but in the same listing with ATE, ATEs and ATR. I'm not sure what relationship KZ has with QKZ but there seems to be some overlap in their product lines.
