Hello,
I'm following this thread for few months now, i have bought the ED8, ATE, ANV, ED10, ED9.
I'm not a pro, but to my ears they all sound good and some better.
One day i found a really interesting pair of IEM on aliexpress, called DOBOLY Q18.
And they cost.......wait........3.79 USD.
They kick all of the KZ's ass's and for third the price.
They're supposed to have JCV HA FX500's drivers.
Anyway, they have the most amazing bass i have ever heard. I can not describe them because i don't have the vocabulary.
