Very initial thoughts:
bass: With no burn in and flat (through my Sony S545 dap) is approaching (not quite there at this point, but approaching) FX700 quality with a tad less quantity. This is good in my book. Doesn't have that JVC timbre, but to not be a wood driver, it's not far off. I would say quality-wise, bass is between e-Q7 and FX700. Again, this is with no burn in fresh in the ears. Funny thing is I forgot I had set a custom eq setting for the Sony when I first started using the DDM. The bass was punched with the clear bass. At that moment I thought I was hearing FX700 quantity bass. Then I realized I didn't have it on flat. lol.. Bass is fantastic so far.
mids: To me, this is the heart of the Radius DDM. I can tell this is the meat of the earphones already. Haven't heard female vocals yet, but the Lenny Kravitz' and Robert Plant's vocals on the tracks I listened too were very detailed and natural. I hear nuances already that one doesn't pick up in other IEMs in vocals. These nuances show voices even more so than in the FX700, which has lots of micro details. I would say the e-Q7 vocals are a bit on the warm side, so sometimes it is hard to pick out those nuances and details in the vocals. But you hear it here. Would I call these IEMs analytical? No, not at this point, but they are pointing in that direction if this makes any sense, but they are not Eytmotics by any stretch of the imagination
As others have said here, the DDM shines on guitar, but I dear say the e-Q7, Miles Davis and FX700 have a new challenger to the throne for strings section. Man, the decay and resolve on orchestra strings is something to behold (and hear). Just beautiful!! All this straight out the box. I am more surpised than any of you that I'm typing this. And the piano is gorgeous and natural sounding as others have said.
treble: I found the treble to be there in the music just fine. It's not the focus on these phones (so from what I 've read of CK10 lovers, you might be disappointed), but it's not hidden at all. And it sound natural to me also. These phones do seem to dictate the instruments as it was recorded. If the treble instruments were the focus, that's what you will get, but most of the music seems to be pushed throught the mids first with great bass and decent treble, but somehow the sound is balanced.
That's it for now, but I can say in the first 10 minutes that these are more than worth its MSRP. These are a steal! Oh, I didn't have any fit issues really, but more on that later. If you have real small earlopes, you may have a fit issue I'm afraid. And I'm using Monster hybrid tips (medium small). More impressions later buddies. Happy Listening!
