You did the right choice, in my opinion. There is so many serious and professional CIEM companies out there with a far better customer service than JH Audio.
I'm still dealing with their after service for my imbalance issue, and it's a pain in the a**. They almost ignored the detailed explanation I wrote down, and are still telling me it might be the internal components. I feel they will send me back my JH13 and I will still have the same issue...great!
