Regarding the detail, they are as good as any IEM I've heard. I actually noticed the pressing of some piano keys that I didn't notice before with my SF5 on a Schubert piece, but maybe I just wasn't paying enough attention with the SF5.
I haven't listen to any drums, but the bass is also detailed. From what I can tell, it is at least as detailed as my SF5. I'm not good at analyzing bass, but I can pretty much follow any notes made by the bass (orchestral) in a piece.
What I can tell you for sure is that if you are looking for good sound, the FreQs will not disappoint. On the same Schubert piano piece I was talking about, the SF5s had this horrible sibilance (sounds like resonance inside the earphone) that I can't pick up with the FreQs. I can't even listen to my SF5s anymore, they sound spoiled and ugly, heh. When I listen to my SF5 now, I feel like the music has a yellow case and not as exciting. Take what you want out of that. You should wait for some more sound impressions before making a decision.
** I realize I'm making some overstatements. I just got out the SF5 and am listening to the Schubert piece. Yes, I can hear the same piano strokes, but the annoying sibilance is still there, just to a lesser degree than I remember. Also, the SF5 sound isn't spoiled or ugly; it is simply different, and to me, this difference leads it to sound less exciting. But my old statement still stands because every time I've compared the two, there is this result: the highs and mids on the FreQs are better.
I'm not going to make a review of the FreQs because I don't have many earphones to compare it to. I also think I'm a little biased. But I believe they are worth the money because other custom IEMs cost more. For the LiveWires, you're basically paying +$65-70 for a detachable cord and one less driver.
I believe that at these price-points and above, all IEMs will have only minor differences in sound quality. For example, the SE530 isn't that much better than the SF5 in terms of SQ. The determining factor of whether you like an IEM over another is the sound signature, and the FreQs provide a sound signature that I like, which a more open and fresh one.
