, I've recently gotten my R2Pros, but already shipped out the Heaven VII review tour unit I recently had the opportunity to play with. wrote an in-depth review
here on the heaven vii & was able to do direct comparisons against the r2a.
In terms of sonics (from audio memory), I would estimate that the Heaven VII pretty easily wins overall against the flare audio IEMs. (particularly in terms of perceived sound stage and treble tuning which I thought were especially well-done on the 7s). Other than that, I don't really like to make too much detailed comparisons with items I never got the chance to test side-by-side, but the differences in those two particular sonic attributes was significant enough that I am comfortable talking about without a direct comparison. the flare IEMs are relatively more comfortable for me, and are significantly cheaper even at full retail price. since there is quite a large price difference between the r2pro and heaven 7, it is hard to say whether the extra investment is worth the difference in money for you. I would note that is a noticeable difference to both my ears and my non-audiophile friends' ears between the heaven vii vs the r2a. the difference is relatively much larger than the difference between the r2a vs the r2pro (in my opinion). The differences in technically ability between the r2a and r2pros do not seem to be very noticeable to me with the larger difference being their sound signature. perhaps the r2pros may be slightly faster with slightly better overall clarity and bass tightness than the r2as, but really I think the relatively brighter sound signature of the r2pro over the r2a more bass-emphasized sound signature is the more noticeable difference.
I was actually driving myself a little bit crazy with some recent blind testing. Some of my findings were a bit inconsistent, which suggests to me that the differences between them are more subtle than I first initially thought. (Or may also be due to sonic differences from differing fits when I remove and reinsert as well I suppose). I do think you can pick up the relatively brighter sound of the r2pro pretty consistently over the bassier nature of the r2a, but actually a bit hard for me to decide which sound I prefer. Flip flops based on my mood and genre hahaha.
From my recent extensive side-by-side testing, I would actually say that really the difference between the r2a and r2pros are more akin to flavor differences than truly significant and easy to appreciate improvements in technical ability. that being said, I am not disappointed with either flare audio IEM at their kickstarter price point and they do offer easy to appreciate improvements over some of the entry-level IEMs I've played with, particularly in their perceived speed. Bass notes are very tight and clean.
Anyone else with both the r2a and r2pro who engaged in any sort of non-sighted blind testing?
