I'll be there for 3 days in early July. Hopefully that'll be enough time.
I can't get them even if I go out of my way to go to Japan. No offence but screw them then, if they are not willing to let a non-resident purchase their product. I won't waste my time with them then and am certainly not going the extra mile just so I can pay them a ridiculous amount of money after already having paid to travel there. I thought it was already enough that they didn't ship overseas, now this. Why does one have to be a resident?
Well, like others have said already, it's not that they won't do it for you, but you cannot have it delivered overseas. You'd have to stay there in Japan for the duration of like 1month until they finish the CIEMs themselves. Of course, that's likely not possible for some, which is why Jaben resellers exist. As long as you do the impressions at Jaben, you can have a friend act as a proxy as they aren't as strict as FitEar about that.
The reason why they don't care too much about overseas customers is... well, there's nationalism at play. And I can't imagine that the custom market is really that profit oriented for FitEar. I believe they make more in the dental industry. And even their custom market is more oriented towards musicians in Japan, not caring too much about foreign markets.
