Now I'm really upset about this. I looked very carefully at the cabling of the R2Pro and there is nothing, not a single bit of difference to determine l/r, nothing anywhere on the ear pieces either. Why Audio Sanctuary sold this to me in good faith is puzzling. The missing driver issue may still be related to customs, but there is no reason the product should not have these markings. Also, I do not know why Flare would make such a product. I'm going to have to file a claim.
