I agree fully with you : the high price prevents me to be tempted to buy based on only one review...
For Blur zero, besides the fact that I don't like the color combination (would have preferred black shell with blue cable, or white shell with clear cable), they aren't any reviews either. I could not even find the price...
Regarding the Pureson earbuds, they should ship in the next days
But I have to be patient (once shipped, 10-20 days expected before delivery...).
I will post some pics and a quick report once burned in.
