I've been on a run with some reasonably pricey IEMs latey, ie, 64 Audio U10, Shure 846, Sony XBA Z5, Earsonics S-EM6 and Velvet, etc.
I was interested in these Finals after someone compared them to the HiFi Man RE-600, which I also have.
Well, after listening to the IEMs for just an hour, I can say I am really liking them.
They are at the same time warm and weighty, while still sounding very clear and resolving. That's a good feat.
Sometimes when you describe an IEM as warm sounding, there's an expected corresponding lack of resolution. But that doesn't seem to be the case here. It's pretty nice what they did. They were able to get both packed in there.
What I also like is that there's a sense of solid control in the bass and lower midrange.
Again, when you desribe an IEM as warm, there's an expectation the bass will be loose and wooley. Again, not so here. I was actually surprised and pleased at how firm and authorative the bass sounds.
No, it's not basshead level stuff. But the bass is firm, solid, taut, and more importantly, propulsive and it really keeps the beat going well. Very engaging, and very fun as the bass here really propels the song forward in an exciting but controlled way.
I've had some IEM that are great in a lot of ways, but just don't keep the beat well, and end up sounding confused and ultimately boring. One that comes to mind is the Westone W40. So good in so many ways, but I can't for the life of me get it to sound rhythmically competent. It just doesn't keep the beat well enough for me to enjoy rhythmic music on them. And that's a lot of music.
But these Finals are good in that way.
These aren't treblehead IEMs, either. While there's enough treble that I'm personally satisfied with it, those who love a sparkly treble focused sound won't find enough treble for them. The treble definitely does not draw attention to itself. While the treble is still crisp and resolved, it's slightly reduced in level and takes a back seat to the midrange.
I'd say that these are probably more resolving and exciting than the RE-600, and I'm actually quite happy to use these as my daily drivers over my more pricey IEMs (still great sound, but less worry about losing or damaging them).
In fact, I like them so much I'm going to pick up a second set.
FYI, I've been driving them with an Onkyo HA-200 portable dac/amp. That's know to be a slightly warm sounding amp, but even with that, the pairing doesn't sound too warm to my ears.
Next to try is the xDuoo XD-05 with Burson V5i, which someone recommended as a great pairing. I haven't tried it yet, but owning and knowing the sound signature of that very xDuoo setup, I think this IEM would likely mate really well with it.
