After losing a piece from my Vsonic VC-02's I decided to get something really cheap for now. These cost $7.18 on Amazon. Bass response is better than anything I've heard in this class. It's actually almost overwhelming at the low end; this is the first time I can remember EQ'ing bass down for an IEM, especially a cheap one. Isolation is surprisingly good. Highs are a little lacking, and maybe the soundstage isn't perfect. Again, these cost $7.18 so you have nothing to lose.
