Today marks my 365th day of owning the i4s, they are still absolutely my favorite, no other headphones have the combination of soundstage, deep tight bass, smooth vocals, portability, comfort, and yes I mean
comfort
initially when I went through and tried all the hooks, earlocks, none of them fit well, my ears started hurting after 30 mins,
so I just took it into my own hands and made my own headband (you might have seen this before but I finally remembered to upload the 3d files)
It might look jank, but with this setup I can wear them for over 8 hours non stop, there is no more sore spots, the eartips are basically floating in my ears, the weight of the headphones is spread across my head like regular headphones, except unlike regular full size LCDs these don't weigh 50 tons, I can comfortably say these are way comfier than all planar headphones out there just due to weight alone
if anyone wants to play around with the models:

you'll also need some m2 screws to secure the hook piece to the main band
