It's too early to say too much about the DZ7. I can say, however, that the DZ7 is the earphone that I hoped the QT5 would sound like (but apparently fell short base on quite a few impressions I saw on this page). The theme here (i.e. sound signature) is forward mids with a very nice full instrument separation. The highs aren't harsh at all, but I can't help but think that four BAs are concentrated on various frequency ranges in the mids. Vocals are forward and clear (and of course, not thin at all). Now, the bass needs burn in before I can really say what it's going to do. Oh, it is there, but for those hoping for basshead levels, I'm afraid you might be disappointed. This is a midcentric earphone. The bass is there if the song calls for it, but it doesn't stay on full blast like that infamous "can't be named" three-driver hybrid. Now, what the bass does upon burn in may tell another story. Right now, it's pleasant and verseral.
I opted for the MMCX connection, the cables that came with it are capable, but I will be switching to an upgraded silver-coated cable. It's a very full and gorgeous sound earphone that plays jazz, rock and soul music with a very slight warmth. Let's just say I was expect worse than what I heard, so I'm pleasantly surprised. Oh, there are two sound tubes that I can see right now. The build is solid and I don't see any QC issues (and I'm looking for them). That's it for the moment. I may give fuller impressions after a good burn-in and much more listening.
