I blind bought them as I was curious, and at the time after $12 Western Union Fees and shipping, I paid just a little over 100 for them, with neither of us really knowing how much shipping would cost, so I overpaid to be safe. As far as buying them, you talk to him on Facebook, and he'll ask you a bunch of questions in order to build you a truly custom earbud. I'm currently in the process of ordering another two, but Facebook decided I was getting hacked, so I'm waiting on a response from them to see if I get my account back. All in all, I was quite pleased with the experience, but I may be considered easily pleased by some.
@nmatheis Just got some too, and I'm hoping is enjoying them.
