I've heard in a while-- a genuine "W" shape with peaks in the bass, upper mids, and ultra-high-treble

the end of the wire is stiff and hold its shape so you can hang it around your ear and adjust it just right

Only problem, they have no shape on the blue part

My only complaint is trying to get the cord to wrap around my weirdly shaped ears

Plus this is the weirdest shape I've ever seen, very hard to get in your ears.

6/10 on comfort as the shape is awkward for my ears.

Love the KZ ZST’s

But these absolutely blow the ATE’s out of the water

I will recommend these to others as much as i can

I use them for in-ear monitoring in live performance, as well as with my phone and am very satisfied with the sound and with the sensitivity of the microphone.
