Update on Saturday June 29, 2013. My IEMs were delivered today with the fit issue resolved. Testing it now.
It has been about 2 1/2 weeks since I shipped them back to Rob.
I am glad that the fit issue has been resolved to my satisfaction.
I have not been impressed with their lack of communication. I heard from them once, twice at most, during that time. While I understand that it is a small business, I believe it is important to keep the customers happy, or at least informed of what is going on. I think people are willing to be patient if they are informed. I can pontificate about whether their business model makes sense, but numerous not-so-positive experience of Head-fiers - mostly with lack of communication and realistic turn-around time - points to some real issues with their business.
I can recommend them with some strong caveats. One - you cannot be in a hurry. Two - don't expect frequent (minimal?) communications. If you can live with these, their price and quality seem to be fine.
