ø9.2mm Dynamic Driver

A frequency response measurement and a quick sound characteristics examination proved that these earphones have exactly the same drivers that KZ ED10 has, thus, the review remains all the same. Not even sure why KZ decided to call them ED11, instead of something like KZ ED10s (similar to ED8m vs ED8s). If you hear any difference it must have something to do with KZ's awful quality assurance when it comes to driver-matching and consistency within the same product.

  • Rich and powerful bass and loud highs.
  • Well built and great looking housings.
  • Very comfortable to wear and maintain a good seal.
  • The sound needs more polishing, especially on the clarity.
  • The splitter is way lower than chest-level and makes the cable wiggly and hard to control.
  • You only get M-sized whirlwind tips with red and wide bores. The S and L-sized tips are just generic black tips with narrower bores.

Comfort & Fit

One of the most comfortable earphones to wear, thanks to the housing design. The housing pushes back against your ear slightly to keep the earphones inside your ears. The noise cancellation is wonderful thanks to the perfect seal. But if the nice whirlwind M-size tips don't fit your ears and you dislike the generic tips, you're in trouble, and you'll have to order S and L-size whirlwind tips separately, like I did.

Lows / Bass

The bass is well present and deep, and you can hear plenty of sub-bass rumble in electronic music content.

Mids / Vocals

The vocals sound nice, but definitely nothing extraordinary. The drivers actually struggle with complex music genres, like metal, and the vocals are thrown to the background.

Highs / Treble

The highs are loud and present, but overly dark, inaccurate and even harsh.
