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.
ø7mm Dynamic Driver
Package & Accessories
Ear Tips - Single-Flange:
M, grey (translucent), ø4mm red bores
S+L, black (translucent), ø4mm bores
Build & Materials
Metal, ø5mm nozzles, soft strain reliefs
TPE, soft strain relief
Silicone (grippy), 123cm, soft, straight
TPE, 90° angled, short, soft strain relief
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.
