Cosonic W3

ø8mm Dynamic Driver


You can find $1 earphones that sound better than this piece of junk. Don't buy these unless you have some sort of headaches fetish.


  • The inline remote looks nice and the 45-degree angled plug is pretty good.


  • The sound quality is the worst I've ever heard. Absolutely repulsive and headache-inducive.
  • Horrible build quality and inefficient design.
  • A flat cable is always a bad idea. They are usually less durable than normal cables.

Comfort & Fit

The ear tips are not so grippy, but I managed to get a full seal.

Lows / Bass

Imagine listening to music when you're ill and your ears are so clogged that you can only heard low frequencies. That's exactly how the bass on these sounds.

Mids / Vocals

What mids? The whole sound is compressed to the low-mids/high-lows. It's like listening through a long tube while your ears are clogged.

Highs / Treble

What highs? There are no highs here.
