Tripowin - Piccolo

? These don't sound like the BL03, but they definitely aren't lacking in bass, especially not midbass. You most likely aren't getting a proper seal, or maybe you got a faulty set. I would actually say that the CCA CRA is one of the most BL03-like IEMs, although the BL03 is better. The overall tonality is quite similar. The HBB is much warmer, with less of that sparkly upper treble that the BL03 has. The only other one I've heard that's a bit like the BL03, but a bit bassier and not quite as resolving, is the Tripowin Piccolo. It also has a more normal fit than the BL03. It's pretty good if you find it on sale - it's not so well known because it was way overpriced at release into a very competitive market at the time. If you're looking for something that sounds *exactly* like the BL03, you pretty much need to stick to the BL03 itself. There's a new version just been released with a 2pin connector. They changed the tuning slightly but I haven't heard it. Not many reviews yet. HBB says it's good, but his review is a bit hand-wavy.

I have the piccolo, I actually like it a lot for female vocals, def recommend it

Nope. Have hexa, explorer, sla3, hola and piccolo

Get the Piccolo, it's too warm if anything, but can be adjusted with eq (6k dip). The shells are crazy good for the price, especially the chrome version. Like I've seen some amazing value shells before but these easily take the cake considering the price, they feel and look like $50+ IEMs. The Simgot isn't bad but the EW-200 and 300 are better so if you're not going to pay more for those I would just get the TRN Conch which has a similar build but better accessories or go ultra-budget and get the Orca. Or go full KZ.

Tripowin piccolo if you can find it... Incredible value, dynamic, a lot of space information, reverberation ,very full bass but is cable sensitive and you have to find the right one, and they are heavy also. Now I'm using that with the cable that tsmr gives with the tame land and they are super because this cable bring the highs a little down. I have penon vortex thieaudio elixir and piccolo stay at the same level but unfortunately the paint can be scratched away if the fall and the nozzles are to affilate and can cut the silicon tips. 

My first was kz d-fi. But they have short nozzles and they fall out of my ears immediately. The first and only time i have such problem. Can't say much about sound, since i simply can't listen them because of this. Next was moondrop chu2. Complete waste. They sounds so damn thin i absolutely hate them. I would ranked them 1/10 Next was kiwi ears cadenza. They sounds... Tolerable i guess. 3.5/10 or maybe 4/10 Tripowin piccolo - that was not a bad buy. Interesting, unusual mid centric (or w-shaped) tuning, i liked them, but not enough to use them as my main. 5/10 or 5.5/10 After that i lost my interest to iems for a year. But month ago i bought kz edx lite. I bought them because they cost for me $0.35. I had zero expectations since they normal price is like $4-5 and they were cheaper than anything i tried before, and i though if i didn't like more expensive iems there is 0 chance something so cheap would be good. But then i tried them i was immediately blown away how good they sounds and ofc much better than i expected. 7/10 Couple of days ago i bought kz edc pro. And i think they will became my main. Their resolution is just much better than in edx lite. Use edx lite in next day feels like watch 480p after 1080p. Honestly both has pros and cons, in sum i liked lower half of spectrum more in edx lite, but higher half of spectrum in edc pro. Edc pro less universal, electronic music sounds great, but any real instruments sounds less natural than in edx lite. Female voices, higher male voices, electric guitars and some dubstep synths sound thin. Kick sounds harder. Its not about quantity of kick, they just sounds different, and i like softer kicks in edx lite more. Edc pro sounds much more V-shaped, they brighter and kick take more attention than in edx lite. Soundstage is much better, in edx lite it almost dont exist. So, while i think that edx lite is equally good in every genre with any instruments etc, unlike edc pro, but the resolution is just much better in edc pro. 7.2/10 Basically reddit meta was waste for me (including tws - moondrop space travel and over ear - koss ksc75, didn't like any of this) So i don't trust reddit anymore

Qkz x hbb … dull bass and cheapest sound ever. Maybe they are little better for gamers. As an music admiring adult I was more than disappointed… they are going on eBay soon. Jumped on the hypetrain with that shitters and won’t do that again. Had to shoot me two new sets to get over that disappointment emotionally: Tripowin Piccolo and KZ Saga. They are both so much better than the Qkz x hbb.

Tanchjim Bunny Tripowin Piccolo Both better than anything on your list. Or, if your budget can stretch to $50 USD, get the Kefine Klean and thank me later.
