Deftone, the Flare R2Pro are very good IEMs. They are very linear and neutral sounding, and amazingly natural and coherent. The Flare play music the way it sounds. They don't add excitement. Sound signature is not v shaped. They don't amp up the bass or have over boosted high frequencies. The extreme high frequencies are slightly attenuated.
The Flare do a few other excellent things . They have the ability to put a soundstage more in front of you vs inside your head. The balanced pressure design changes bass perception. It is a little hard to explain. There is the correct amount of bass, but it doesn't build up pressure in your ear. It is more like hearing bass from speakers. I find it less fatiguing than other IEMs.
The Flare are pretty inefficient for IEMs. If you like music loud, the Flare will do better with either a higher power dap ( I use the PonoPlayer) or an amplifier. It is amazing how much power the Flare can handle. The small micro drivers can also play quite loud.
A multi driver IEM with balanced armature drivers may pull out a little more detail. It is usually at the expense of a more ragged frequency response. It is very hard for multi driver BA's to achieve the same coherence a single fullrange driver has.
The Flare probably don't any one thing absolutely the best. But they do every thing very well. It is this balance that makes them so special.
The Flare are some of the most comfortable IEMs around. They are so small and light weight, and can be worn for hours. Some people do not care for the Comply memory foam tips. The Flare can be a little finicky with other tips. All tips change the sound at least a little.
Flare said there will an announcement in July. You might consider waiting for that info before doing any thing.
Hope this helps
Thank you for your detailed post, its cleared a lot up for me. i will wait until july like you say then if it does not interest me i will pick up the R2pro for listening at work.
keeping a close eye on things from here on, thanks again.
