Ok sad day, got the lottery ticket of qc issues with the Tangzu Wan'er Sg 2 Red, any alternative to go for?

So yeah. I thought I would be part of the lucky ones who got the good ones, but no, out of the box the right piece doesn't even work at all. (Swapped cables and all, it's just the iem).

So I'll just forget about them, but now I need to make a random purchase to make up for it.

Same idea, just looking for something with good bass.

Had the Castor pro bass version which is great, but I'm getting tired of the V shaped signature, the treble on some songs just make it imposible to enjoy music at good volume without having a headache.

Idk what to go for next. I mean below $200
