Wiljen & B9Scrambler are both experienced reviewers. I think it's important to note that proper tip selection is important and can affect overall sound, even more so in earbuds. Wiljen chose note to use eartips though, which I found strange. In my experience, this leads to an overall thinner/more neutral sound with less isolation/bass. They both seem to agree though that sub-bass reaches fairly deep and treble is slightly elevated without reaching piercing levels. Femals vocals seem to be thinner than male vocals, so I would think this translates to a more v-shaped signature, how V-shaped could depend on foams/silicon eartips. Nevertheless, 4 stars out of 12 reviews does seem to suggest these are pretty devent earbuds.
