ø12mm Dynamic Driver


Altough these earphones look and feel exactly like the ROCK Mucu, it seems the sound is noticeably different. The Ewin are quite cold and lack that bassy punch the Mucu has. The sound is discolored even further and is very dissatisfying in comparison and the sudden peaks the Mucu has are even more uncomfortable on the Ewin.


  • Ridiculously loud, no amplification needed at all.
  • More than decent build quality.


  • The overall sound is quite dark, cold and unnatural. The bass is weak and struggling.
  • An extreme peak near 600Hz causes major discomfort, almost headache inducing.
  • Not very suitable for small ears.

Comfort & Fit

These earphones were designed to be comforable, and they are, but I couldn't get a proper seal without pushing the earphones in while listening to music. Even with a close fit, these earphones sound unbearably uncomfortable.

Lows / Bass

The lows are lacking and inaccurate. Unlike ROCK Mucu, these lows are not even capable to warm up the mids, and that makes the whole sound cold.

Mids / Vocals

Overemphasized on an uncomfortable level. They are significantly louder than the lows or the highs which makes everything sound painfully loud. Aside from being loud, they are cold and lack any depth.

Highs / Treble

The highs sound far away and are gentle on a non-impressive level. They get totally destoyed by the mids and even the lows. Even so, some sudden peaks can be noticed, which add to the weirdness of the sound.
