I've been using these for a while now, and I really like them! Bass is tight and just enough for my taste, mids and highs (Comply tips decreases sibilance) are detailed and froward as good as th Etymotic hf5. It has a decent soundstage. Very comfortable with the supplied Comply foam tips. Quality wise, I have had no problems for 4 months now and they still look new. From what i've heard, the 700 is not very popular here in headfi, and not much people have it. but still I thought they deserve more attention so I've made this thread.
