ø7mm Dynamic Driver

This review is almost an exact copy-paste of the classic KZ ED2, simply because they have exactly the same drivers and they sound exactly the same.

NOTE: They look like they have an open-back design, but their backs are actually sealed behind the meshes.

Buy on
  • Bright and detailed mids and highs, with more than enough bass to keep the hype going.
  • Excellent design and decent build quality.
  • The lows and mids are slightly pushed back on low-power sources.
  • The included ear tips are pretty useless, at least they were for me. They are too "soft touch" and aren't grippy.
  • There's glue residue on the housings' back meshes on the pair I received.
  • The presentation and the lack of accessories and proper tips are quite disappointing.

Comfort & Fit

The pre-applied tips are OK, but too soft and not grippy. I couldn't keep them in my ears without them sliding out on their own. ROCK Zircon's tips worked like a charm, I got a perfect seal and could hear the true nature of these earphones.

Lows / Bass

The bass is clear and precise, with a lot of enjoyable and deep sub-bass, just as long as you really have a perfect fit.

Mids / Vocals

The mids are balanced and precise, yet warm enough for the vocals to sound full and vibrant.

Highs / Treble

The highs are detailed but overly gentle and flattened. Slightly blurred out and not as sharp.
