I have iems with pretty light bass like the FDX1, so I didn't expect them to have a tone of bass right away, the things is the entire sub-bass section feels missing, thus it sounds shouty in the mids and very bright up top, I'm gonna change cables & tips, and burn in some more to see if that makes a difference.
Shouty mids and bright up top is what I heard, too. I normally can judge IEM pretty quickly, I sometimes like them more over time but my initial impressions tend to hold up but with these I hesitated because they sounded so different to what I expected based on the graphs and the few reviews, which are out there (messy sound, basically). I still think I posted my impressions on here a day or two too soon - should've been more enthusiastic, that's all. Hate to admit it, but burn in is a thing with these.
Looking forward to hearing what you make of them in a few days, I do hope things improve for you as they did for me.
