I'm not that regular a user so I have not edited my profile.
When it comes to IEMs I have several. From what I have, the closest to what I want are the Sony XB90EX and the KZ ZS3. Both are good but I wanted to find something better. The XB90EX lacks a remote/mic and for some reason seems to be lacking a bit of punch/thump on some songs, which I find odd when I look at its frequency graph. The ZS3 has that punch, however it also bleeds a bit into the mids. Both the XB90EX and the ZS3 lack some treble extension. I know that helps with the sibilance but I would still like some more treble. I also have the Z5000 which deliver some amazing low end, both extension and punch. The problem is that they have way too much mid/upper bass for my taste and everything sounds dark and congested. The XB90EX and ZS3 also have dark(-ish) sound signature but it's much more tolerable for me.
I was considering the UiiSii CM5, the NICEHCK Bro, and the TRN V20 but dropped them from my list, as I slowly got the impression that they may lack some extension and/or are more mid-bass focused compared to the rest of my considerations which currently are:
- Tiandirenhe TD08 (the bio-diaphragm it is using intrigues me, as my favorite pair of headphones, the CAL!, uses bio-cellulose drivers, and I assume it's the same thing, although I could be wrong);
- Rose Aurora;
- the currently discussed Aritste DC1;
- I-INTO i8;
- and one I cannot mention due to it being banned on Head-Fi, which is really regrettable, as it looks quite promising actually, and banning discussions of products potentially hurts users for whom the banned products might be a perfect fit but they would never know.
Before someone mentions it here again, I've received recommendations for the iBasso IT01 and I've read virtually nothing but praise for it. The problem is it is significantly more expensive than the rest. If I were absolutely certain that I would love it, I'd save and buy it, however I was burned once before when I got my RHA MA750 after the ton of hype everywhere. I fell for it, as everyone said they were bassy earphones, had great low-end, etc., etc. I wasn't expecting basshead levels of bass but I wasn't expecting them to be bass-light either, but they were.
