Btw if you buy these, watch out. There is a plastic layer on the IEMS that will come off with heavy use. It ruins the aesthetics but functionality it still works
HertxzI can confirm this is a known issue. I contacted Ikko about it and she stated as exactly as mentioned above. It’s a factory applied layer that may peel off with usage, but it in no way changes the sound of the iem.
I bought my OH10 at the beginning of 2020, so perhaps this is no longer an issue.
