Hi guys, I've been asked by Mr. Suyama to help out with communication between custom customers and the FitEar office. I think Mr. Suyama trusts my Japanese more than I do, but I am relatively familiar with FitEar products and should be able to help out with the 'crack'. Evidently, as noticed late in this thread, it isn't a crack. When the resin dries, it can contract. It simply is unavoidable with today's manufacturing process especially with a fully solid acrylic/resin shell. Also, as noted, there is no effect whatsoever on sound or longevity of the earphone. It is 100% a cosmetic effect.
I will chime in with more information as I have it.
Please don't PM me with questions; it is better to keep questions in this thread so that anyone can access the information.
I will be gone to Hong Kong from Saturday and probably not attached to internet. I come back Wednesday next week.
Otherwise, I'll be in this thread to help out. I expect that Frenchbat will be here eventually, too, as he got a 335!
Thank you for your information Shigzeo san. I'm waiting for reply from them about other "crack" that I found on both side. This one is definitely on the surface. I can feel it with my finger. I suspected that it happen at the top lacquer layer.
