I would like to read more about Penon iem here, but there is only a few info and impressions all I can find.
When I read DGS100 thread, I felt like I'm at home.
It has great clarity, details, and stage, boomy bass is moddable (front hole assignment)
Despite sometimes being overwhelming, it's bass is quite different, I think it's very organic and quite lively.
Any others sharing similar opinions?
