Fit/Comfort the cable and IEM are pretty heavy and no matter what I tried these always felt like they were falling out of my ear if I moved at all so long sessions with these are a no at least for me
Sound these are pretty odd I've seen other reviews some say they are harsh/shouty and others say they are big bass IEM's in my experience they are neither, I found Vocals on these to be amazing, bass was kind of all over the place with some songs having the bass recessed to the point of almost not hearing it and others being solid ear hammers, I didn't find these fatiguing which I generally do with harsh/shouty IEM's these are very clear sounding with nice detail and pretty good soundstage/separation
Swappable Filters tbh I didn't really notice a difference but I ended up swapping back to stock
TLDR I think for the $175 these were going for they are pretty good to me these are just better Shuoer Tapes which a lot of people said were budget detail when they came out
