Ziofen H9
Ø10mm Dynamic Driver

The very curious looking H9 by the pretty unknown brand Ziofen turned out to be a refreshing listening experience in the mids department. Smooth and detailed mids, fair bass and crisp highs.

  • A very clear and bright sound quality, especially the mids and upper-mids. Definitely made for vocal-oriented music.
  • Superb build quality, simply rock-solid.
  • A beautiful presentation in a high-grade package and a bunch of accessories.
  • The bass doesn't go very deep, there's basically no sub-bass. You might feel a lack of punch in the sound.
  • The maximum loudness is relatively low on low-power sources. You might want to amplify these slightly to get them to their full potential.

Comfort & Fit

You probably won't have any trouble fitting these into your ears. I did have a problem but I used ROCK Zircon's tips, which look better on these earphones anyway.

Lows / Bass

The bass is stable most of the time and is clear, but not deep enough. The bass response doesn't go very low and sub-bass can rarely be heard.

Mids / Vocals

The mids are very detailed. The vocals are clear and precise, and you can hear details you rarely hear on other earphones.

Highs / Treble

The highs are precise, crisp and loud, but not painfully piercing. Its loudness is proportional to the mids' loudness.
