ROCK Mucu (RAU0515)

ø12mm Dynamic Driver


A new product by ROCK, the Mucu sports earphones. These earphones are very loud and perform quite good with light music styles. However, ROCK will never reproduce the success of the legendary ROCK Zircon earphones if they keep releasing mediocre earphones.


  • Quite impressive bass performance for earbuds, depending on the fit you get.
  • Ridiculously loud, no amplification needed at all.
  • More than decent build quality and a stylish design.


  • The overall sound is somewhat tubby and muddy. Clarity isn't their strong side.
  • An extreme peak near 600Hz casues some discomfort.
  • 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. You shouldn't expect a seal with these earbuds, obviously, but for the bass to shine, you'll need at least a close fit.

Lows / Bass

The lows are very punchy and get quite deep, but you won't be able to enjoy its true depth because getting a proper seal with these is probably not possible.

Mids / Vocals

Somewhat overemphasized but on a relatively comfortable level. They are very loud, but overshadowed by the lows, and most of the detail sounds distanced and muffled.

Highs / Treble

The highs are there but are relatively muffled in comparison to the lows and mids. However, there are quite a few peaks in the upper-mids and highs that are sudden enough to turn the listening experience to being uncomfortable. I found that snare drums are annoyingly loud.
