Hum.......................okay, you don't hear them but suggest them. You know that I start this thread right? Just to say i'm no dumb even if I can sound strange. TOLT iem are a myth for me. And my fascination about Chifi is for relative value, wich can be for construction or sound. ZS5 is a good exemple I think. As well as lot of 50-100$ chinese IEM. Perhaps I was bad lucked with my Westone ES2 that cost 600$, that I find good sounding, but still very far from perfection and less good sounding than lot of sub-100$ chifi iem I own now. I know too that subjectivity of sound perception is a big aspect and that even if i was buying ''TOLT'' iem, same disease will occur, wich is about soudsignature that can't deal with wide music style I listen too, from classical and jazz to complex electronic,rock and indie. For the GR07 there a clone at like 18$.....and the whizzer look nicely build and can be find for about 60 or less at alisale. I'm thinking to find something in 120-200$ price range on Ali for less than 100$ cause of sale, so, yep, the money constraint isnt perhaps a factor of stress for you, but for me it is, and it look like I already have my answer, was looking for enlightment, not pseudo-pedagogical sentences. Anyway, i'm not mad here, just very bored by what I (already) read.
