I have a ton of sub-$200 IEMs, and these are fantastic at this price on the site. I have the DM6s too, and when used with memory-foam eartips I think that these are right there in SQ and even better built. The best $100 IEM (with thanks to Drop!) I've ever heard. The cable is quite good too, so I'm very happy with my DMGs.
Update: Still lovin' these. The blue anodizing is getting a little worn on the edges (I don't treat these very well, I admit) but they are performing perfectly. I generally use Comply memory foam or Dekoni foam eartips with my IEMs. Based on other reviews for other IEMS, I thought I'd try out some SpinFit silicone eartips (which normally I find don't seal well). However! On these, the SpinFit eartips worked great, they seal very well and really brought out the bottom end of these IEMs. The SpinFit eartips take these to a new level, I enjoy them even more. Plus the stock cable has still held up, no issues after 5 months. Very good quality. Overall, my daily drivers around the house. Super-satisfied.
