I'm excited to hear from them, hoping that the impressions I'm getting from reading reviews of these is what I think it'll reflect in results from either an audio frequency response graph or a matching of my ideal preferences.
I've seen a few audio frequency response graphs of the R2 earphone, that looks to have a great mid-forward vocal range, but drops off once it gets to the treble. From reading reviews of the Flares Pro, going for a "live" sound tells me the treble will be quite the opposite of that. If Flare Audio has managed to combine the same qualities I've seen from the graphs of their older product, with the newer spacious sound, these might be very close to my ideal sound signature.
Currently, I'm using the HiFiMan RE800, which I did a review on, here :

explaining not only about that product, but my own preferences in what I'm looking for. The RE800 has great treble, though I wouldn't say it sounds "live", and isn't as spacious say as my B&O Play Earset earbuds. If Flares Pro has that, with more "live", forward vocals, without having forward bass - my bass preference is neutral to having less bass in quantity, then Flares Pro might suit my preferences better than the RE800, which while I like alot, is not forward enough in the vocal range.
I don't want to go the balanced armature route though, regardless that they typically have a response closer to my preference. I've listened to a few ba driver iems, and they don't sound natural enough to me.
