Added: Solaris, Fearless S8 Pro, Cayin YB04
1/2. IER M9 (Scarily balance with top notch timbre, imaging king)
1/2. KSE1200 (Scarily details with outstanding imaging, thin ish vocals)
3. EX1000 (Biggest soundstage for imaging but can be hazy in a crowded track)
4. ER2SE (Cheapest, most coherent, most details at this price range)
5. Rai Penta/ Solaris (Penta - Controlled bass with top notch vocal presentation-lack highs and imaging, Solaris - has controlled bass and smooth vocals but the texture&clarity of the vocals are not good enough to be in the top 3)
6. Anole VX (Outstanding details but sounds artificial, imaging is average - boosted bass is a con - jack of all trades, master of none)
7. CL2/ iSINE20/ EX800st/ YB04 (CL2 vocals is like an old speaker setup, 20&800 are open but with low res, YB04 is more mids and highs centric it sounds coherent enough and well implemented)
8. Empire Ears EVR (outstanding vocals separation but lacks of highs and imaging)
9. Andromeda V3/ Fearless S8 Pro ( Andro is a good all rounder but with lacking vocals, S8 Pro sounds to have better lows extension but still suffer from excellent vocals)
10. CA Comet (Best all rounder for relax warm listening at this price)

I'm a neutral head and prioritize on vocals tonality, my rank is strictly based on that.
honorable mention;
ER4SR - clinical with BAs tonality
ZS5 - cheapest IEM that took me into the game
ZSR - more intimate of ZS5
Galaxy Buds - the best wireless ive ever had hands down
comment 1: Ramble about anole VX; VX tried to beat the crowd with its reso performance but forgot that they boosted up the BAs bass. There is missing in mids warmth resulting it to be somewhat fake-ish sound together with boosted highs and the dip at 6-8khz to add more salt. Number 6 is given for the respect of its resolution but I'll pick 7,8,9,10 to enjoy music in everyday life. Again, this is strictly my opinion.
comment 2: I want to bring up about vocals that im talking about here. Good vocals to me when that set succeeds on giving vocals its own path in a track. Meaning, it is well separated from instruments and has good full bodied; a good warmth and weight to bring emotion to the vocals. With good tonality or in another word, life-like sound. Texture and clarity of the vocals are the factors contributing to emotion.
comment 3: er2se achieved at the top 4 considering sonic performance/price. Thence, it remains at number 4 for that value but the fit is not always for me.
