When I'm looking at prices for the IE800, I'm seeing around the £550 - £600 mark! At full RRP, the IE800 is about £650. At full RRP, the R2Pro is £400. Tell me which is cheaper.
The R2Pro has not been released yet - all you are going on is full RRP and yet that is still cheaper than the reduced prices of the IE800 which has been on sale for about 18 months already. Wait 18 months and see what price the Flares end up at after that time.
And having not heard the Flare Audio products, where are you getting your opinions of it from? You sound like you have some wierd grudge against an inanimate object?
If you read this reviewer's take on the R2A's treble:
http://headfonics.com/2015/05/the-r2a-and-r2pro-iems-by-flare-audio/2/ you'll see that he compares it favourably against the JH16 (CEIM) but noting that it lacks the treble prominance of the JH16 which he is used to and so is expecting to hear... yet at the same time, states that the JH16 is fatiguing whilst the R2A is not. I guess then that he's discovering that the R2As sound more natural but he's never heard that natural presentation, instead always gone for wow-factor of an exaggerated top end . Shame then that he calls this a negative whilst I call that a positive.
I've not heard the IE800 but certainly my R2A and R2Pros are pulling things out of the bag spacially that I only get from my Acoustic Energy AE2 Reference speakers, not other headphones or earphones. It's not all the time of course as it depends entirely on the material - if it was all the time, it would be false.
Definately you should wait to hear the Flares for yourself before making judgement against them.
