First of all, thanks to everyone who has answered my question. I took a good hard look at everyone of the products mentioned.
Now, someone has pointed out that emphasized mids and fun sound signature are usually contradictory (which I blame on my lack of knowledge about audio stuff in general, haha), so just try to ignore the part about the "fun" sound signature. When I said "fun" I meant that it can deviate a bit from what people may consider neutral/natural, as long as it doesn't deviate too much. Rest still stands though: emphasized mids, also maybe a decent amount of mid bass, even if that means that sub bass is slightly recessed, and also recessed highs (mainly because I really hate pierce and hearing fatigue). Basically: warm sound while keeping the bass at bay.
I've looked at some of the options presented:
ED16: does look very good, but some have pointed out its not perfectly neutral sound signature, so I've been looking at others.
TinAudio T2: looks even better than the ED16, but what worries me a bit is the part of
this review where it says:"Unfortunately, this treble will probably be too much for people with sensitive hearing". Simply because my hearing is pretty damn sensitive, and also because I'd prefer recessed highs.
Unfortunately, many options were removed immediately due to the lack of a removable cable which I need for bluetooth.
So, I've decided to go on
audiobudget.com and compare some of the other IEMs to the T2 and the ED16. Now I'm kinda stuck at the NICECHK Bro: non-piercing sound, not muddy, mid-bass emphasis, bright mids all sounds pretty good and also a bit more true to my taste compared to the ED16 and T2. Also, MMCX so I can get myself a bluetooth cable.
Unless anyone tells me that getting the NICECHK Bro would be a terrible mistake/ not actually what I want and I just think that it is what I want because I'm really bad at audio stuff and don't really know what I'm reading, I'll probably get them, haha.
Again, thanks for everyone who has answered so far and thanks in advance for every coming answer!
