I used to lurk this thread back in the day, still have my xb90ex that I now only use for quick things on the computer now. Keep up the great work guys.
I got in touch with [COLOR=212121]Masao Kamikodai (great guy, I had to use a bit of Google translate but we managed to get there) from [/COLOR]E4UA and managed to get an order for the Sony ex1000/ex800st/7550 to MMCX adapter and it's pretty well made. The cost of it and the shipping+import tax stung a bit (£174, yes I know that's a crazy price for an adapter) but I reckon it was well worth it. I can now use any MMCX cable with my ex800st but also my bluetooth cable that I got recently. I believe it's possible to make your own for much cheaper if you're handy with DIY using the Luna Shops parts perhaps but I don't trust myself on that part but inspiration for anyone that wants to give it a whirl is there.
I figured you guys might want to know since MMCX cables are much more common than the Sony cables, you'll get a greater variety of cables to choose from and use. Get a pair of ex800st or ex1000 with mic and controls for your phone? Sure thing.
I've also got some adapters for Trinity Audio's PM4s, although they don't fit as nice as the Sony adapter. Picture below:
