Smaller cable type, now.
I spent some time listening to the RE-Zeros last night, and I must say, they are very, very nice phones and detail monsters. I used both my new ZuneHD amped via HP out and the T3, and amped via LOD/Touch and the T3. I also listened to them without an amp, and while they still sound good, the T3 gives them a little more depth and body, if those are the right words. Either way, they are an excellent value and another fine IEM from Head-Direct. I do have a little trouble with the rubbery cables and the shirt clip. The cables don't relax, so they end up rubbing/bumping into my face somewhat. I guess I should try them over the hear.
I settled on some smaller UE single flange tips, which have large sound tubes, and they work very well. I also used some Complys, but they seem to muffle the highs a bit.
Either way, the RE-Zeros are very fine, mid/high focused IEMs. Not that bass is MIA, but they are not bassy phones, much in keeping with the HD IEM M.O. I would write a proper review, but I don't have the review chops of some fellow HFers. I know Joker is going to review them at some point.
As a comparison, I then listened to the DBA-02s, which to me are still preferable to the RE-Zeros, but it's close. I think the DBAs just deliver a more overall musical sound, fuller and richer, across all frequencies. But having both is very very nice. I would say the RE-Zeros do outperform the Ety MC5s, which I also have, but the Etys are less expensive and are much sturdier and offer better iso.
Anyway, those are my thoughts on the RE-Zero.
Oh, and the adapter, the new cable based one, is fine. No weird static noise, like the block adapter that I initially received.
Of course, I would love to hear them through the new HD portable balanced amp coming out as a partner to these phones.
Update:
Over the ear solved the microphonics issue.
