The pair I received had identical housings, instead of symmetrical ones, which in this case means that the left earphone has the wrong angle, and it doesn't fit well. Not sure if it's a specific factory defect or an absolute manufacturing failure.
Lows / Bass
The bass is powerful, but also sounds brightened-out by the quite harsh and darkish highs. There's something imprecise about these lows. They don't sound as impactful as they should, and aren't so deep.
Mids / Vocals
The mids are mediocre, sound somewhat pushed back and slightly sibilant as a result of upfront highs. They are OK, but nothing too impressive.
Highs / Treble
The highs are loud and slightly harsh. There's a darkish tone to them which makes them somewhat unnatural. It sounds as if the highs are so exaggerated that they sound too close to your ears.
