Thank you all suggestions from you all, unfortunately I dont have easy access to get the Bomaker Sifi or Fiil T1X and stick on my budget limit $30 so in the end i bought this QCY T5..
Anddd in the bought the new Haylou GT1 Plus out of curiosity but they are still on the way. The GT1 Plus have 7.2mm biocellulose driver and qualcomm chipset.
Ok so now on QCY T5, they have nice signature, more subbass than mid bass. Bass decay isnt so fast which i expected, ok mids, clarity is standard but for their price considered very good, boosted upper mids on 3khz but not as harsh as previous KZs, but can be a bit aggressive and shouty on high volume level. Highs have sparkles, sibilance free highs. Details and soundstage are aspects that amazed me for a very cheap TWS with decent details. Overall a good buy without fear of lost or drop.
Not a fan of the shape and the fit also not easy plug for me, with azla sedna tips they are the best to my ears but the case won't allowed them to snug in. I use the tfz wide bore eartips in the end.
To my surprise crinacle have measured this also and he gave C+ rank and say that they are a decent set.
Here the measurement from him, all credit goes to him
I have the QCY T1c too, compared to them the T5 have more clean bass, the T1c suffer from mid bass bleed, T1c sounded warmer overall and have more body weight, T5 sounded thinner on mids especially lower mids. Soundstage is larger on T5 by quite some margin, and more detailed also.
Aside from sound quality, T5 have benefit with gaming mode (3 times tap on right iem) to have better latency while watching movies or playing games (but no 0 latency, thats gimmick) but they are better on delays, almost in sync.
Will share the Haylou GT1 Plus later also when they are arrived.
