This won't help much, but......Anaconda had the easiest options..

I was on the search about a year ago - found all the cases and ear pieces to be ridiculously expensive and could only be submerged to 3m (so no good for me - needed it for diving).
I ended up making my own... pieces of 40mm pvc pipe and access to old ARGA mask gear..

...I told you it wasn't going to help much..
