I've recently bought these IEMs from Temu, because it was just like $3 and it was from a brand I didn't know and curiosity took me over: KCKZ S72:
These are the worst IEMs I've ever used. A shit ton of bass, muddy mids and scratchy trebles. Bass is overwhelming, and I'm not ever exaggerating.
There are some decent ChiFi IEMs at this price range: KZ EDX Lite, KZ EDC, QKZ AK6 etc
I've literally took it out and broke it after 15 secs of usage.
I still love my Tangzu Wan'er 2s and 7hz Zero 2s by the way, they cost about $20, but quite decent pieces.
