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.

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.
