I suspected that by taking intras XBASS is called the midrange / treble would be truncated, but then they are mostly very dirty, it blows so much that it's almost painful. After 2 minutes of listening, I've thrown in the closet. Even correcting with EQ, treble extremes are too present and whistles that more than anything else, especially since the medium is too low. For bass, these headphones offer a slightly overweight compared to low-end intras but nothing transcendental good. In short, even at 20 euros, it's not such a good report. I am rather disappointed with JVC on this one.
