Looks cool. The angle of the part that goes into the ear look different between the first and third pic. Third pic looks a bit off on that part.
I’d decrease the transparent parts tho, goes a bit overboard here. Especially since it’s an IEM. The in-ear parts will look like hell for the type of users who fon’t clean their headphones (or themselves) very regularly. Maybe have another look at Nothing ears to figure that part out.
Btw, there was a cool “modular IEM” post/idea here few days ago. You can check that out..
Edit: that “2000’s japan” style goes nice with Nothing products. I mean.. it goes well with anything.
