KZ ZS3 In-Ear Earphones

The sound quality of these phones is exceptional.
I have no issues with the sound. Perfect.
Not gonna get into the details of sound signature, but basically, this is one of the best earbuds for the price.
These earbuds sound great! They have a V-shape sound signature without killing off the mids.
These headphones are loud, snug, and sound great with respect to their price.

What customers say about "Features"

KZ ZS3 In-Ear Earphones

The memory wire that wraps around the ears stay intact even during high physical activity.
The included silicone earbud tips are comfortable and isolate sound very well.
The mic button works well and has a nice, solid click.
The actual earbuds are detachable from the wire so If you're scatterbrained like me, you might end up losing an earbud like I did.
These have not stayed in my ears during running, although I will be testing this again with the different ear tips.

KZ ZS4 High Fidelity In-Ear Headphones

They are comfortable and stay in my ears.
No falling out like others have!
They fit in my ears better than any other ear buds I've owned.
Comfortable design. Stayed put while I work out.
Clear wrap on memory wire is a little ugly. Not great for live music monitoring. Tips are bad. Buy memory foam tips and never look back.
