KZ ED9
Ø6.8mm Dynamic Driver

One of KZ's flagships, KZ ED9, is up for the test. Honestly, I really don't like overly emphasized highs. Too much definition can be exhausing rather than impressive. However, I won't call them bad earphones because of that, because they are quite high quality when it comes to their extraordinary sound signature.

The sound similar to KZ DT5, only with a more balanced bass response (much less sub-bass), and more defined highs.

NOTES:

  • For slightly more sub-bass and slightly more pronounced highs, you can use any of the filters included with Winintone RG-EB601.
  • The filters included with KZ GR cannot be used with these earphones, but you can use the filters included with these earphones with KZ GR.
Pros
Cons
  • A brilliant sound quality, well defined across the whole frequency range.
  • Excellent volume levels even without amplification.
  • The ability to use different filters for different sound signatures.
  • An excellent build quality.
  • The highs are exhaustingly sharp and loud. Too much emphasize on the highs isn't always such a good idea.
  • Noticeably heavier and longer than most earphones.
  • Seems like the two wide filters I got are different, and they look like they were made of a different material. One of them completely removed any bass from the sound, while the other one just balanced the sound. Make sure you get the right ones (two balanced filters).

Comfort & Fit

The earphones are slightly heavier than most earphones, and at the same time they are quite long, so just like with KZ GR, they might be slightly loose in the ears.

Lows / Bass

Although the sub-bass is pretty minimal, it's pretty quick and presice. Unfortuantely they are significantly overpowered by the sharpness of the highs.

Mids / Vocals

Just like the highs, the mids and vocals are very defined, sometimes even too defined, bright and confusing. It's a matter of personal preference.

Highs / Treble

The highs are very defined and you can hear every silent chime and whisle, but it really causes discomfort because they are so loud and sharp that it makes my head ache.

Wide filters*:

  • For this measurement I used the proper balanced filter on both channels. The other wide filter is either defective or just vastly different.
