I was completely taken aback when I started listening. I wasn't expecting these things to sound this good at this price point. "Budget price, not sound!" Is there an echo in here? The upper midrange and top end is the real strength of these headphones and something that isn't common among many peers. Overall, these are very good sounding in-ear headphones.
They aren't perfect, however—no $99 IEM is. I found that their performance was dependent on the kind of music you are listening to. And, the strengths and weaknesses will manifest themselves differently depending on the genre or song. I'll try and detail some of the perceived tradeoffs and preferences so that you can make the best decision. (I must also note as a disclaimer and for the record that some of these tradeoffs I note below could certainly have been exacerbated by the awesome seal that the Comply memory foam tips deliver).
