I actually bought a pair of those zs10 earphones a few weeks ago for $45 to replace a very old pair of in ear Klipsch that were 10 years old.
I was honestly shocked how good they sounded for any price never mind $45.
Admitted never hear $1k in ear phones and likely never will but hard to imagine them being 22.2 times better!
YMMV
