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.
