LaoZhong LZ-Z03A
Ø8mm Dynamic Driver

LaoZhong (known as simply LZ) is quite popular for his high quality earphones, offered for decent but not-so-budget prices. I received this LZ-Z03A (which supposedly sound exactly the same as LZ-Z02A) unit for free for reviewing, but you know me - I stay true to my opinions, becuase brands have to know where they should improve on for their next product. These earphones offer a very precise sound, but with overemphasized highs, and underemphasized lows, which makes the sound relatively cold. Some people like it, some people don't. Being a heavy metal and dirty electronic music fan, I like it less.

Compared to Tennmak Dulcimer, LZ-L03A have sharper (but less detailed) highs, and much colder bass response.

  • The sound is highly bright and detailed.
  • Very loud without requiring any amplification.
  • A superb design and use of materials.
  • A nice package with a good variety of ear tips and accessories.
  • The highs are so bright they can cause a fatigue. There's some sibilance to vocals as well.
  • The lows aren't present enough. Makes the whole sound signature somewhat cold.

Comfort & Fit

I had no comfort issues whatsoever. I doubt you'll have any trouble finding the tips that suit you most. The earphones maintain a good hold and seal.

Lows / Bass

Not powerful enough. The bass is shallow and has no impact. The upper frequencies sound cold as a result.

Mids / Vocals

Precise and detailed, but cold and slightly sibilant. Vocals sound loud and clear, but they lack warmth and liveliness.

Highs / Treble

Sharp as a knife. The highs are overemphasized, making the vocals slightly sibilant, and the whole listening experience not so pleasent for those who have sensitive eardrums. Still, the highs are quite detailed and impressive.
