I wasn't certain if the 3D printing was just a "new" way of making existing CIEM models or if it's a new CIEM altogether.
I think the depth imaging was more on the new fitear - mainly due to the bass rendering. Didn't hear much in soundstage, but maybe it's because I didn't focus on it t that much.
I have a feeling the answer is "nebulous". We'll get clarity when things are for sure. Right now only Suyama-san probably has the answer.
So I take it that your first impressions were rather mild? As in not much to hype about?
