there's a HEM1 "Dynamic"? sure it's not an EDC? all HEM1-8 IEM are BAs.
Edit: ah there is one. it's new, ish huh? IMO even if it sounds kinda bad, it should still worth the price as for 20 £ a DD iem with detatchable cable, comply Eartips and negative profile is pretty rare, the negative profile especially as even chifi can't reach that still, most of their design are single size earmould that's too big in comparison. think of it as more of a "throwaway SE215".
I bought and kept my HEM 1 simply because of its size, I also happen to like it's sound more than the SE215. I didnt think I found a good cheap chifi with similar sized body once it's made by Kinera, but forgot the model. it sound pretty good too
