After using these for a few weeks now, I still have no idea how they are priced this low. I own a decent amount of "totl" iems, and I would not have been surprised if these cost over $600. It took me a bit to find the right tips, but now the fit is perfect. They remind me exactly of the InEar Stagediver fit, which is a great thing. I haven't noticed any recessed mids, and I really enjoy listening to classical rock and prog rock with these. They seem to pair well with any source, but my favorite would be the Mojo or Opus 2.
