The other connectors are supposed to be available separately, but I can't for the life of me find out where! Anyone else have any luck with that?

It looks like these ear hook adapters are the same as the bt20 pro's adapters. If that is the case you can get them through aliexpress. If you want to use the mmcx connectors with more than one set of iem you will want to get more than one set of the adapters. I had a bad internal connection develop in the adapter and that's how I found them on aliexpress.

My question is are they better than KZ AZ09 which have horrible bluetooth signal drop. I love my IEM's but have yet not been able to find a cordless solution. Any assistance would be greatly appreciated.

I can say that out of all of the bluetooth attachments I've tried the AZ09 were the worst for bluetooth reception. I'm a huge fan of the TRN BT20S (non-pro) and the only problem I have is with sweat intrusion. I have to seal the seam on the back of the unit with superglue. So one thing I noticed as well is that if you have an old version of the AZ09 the contacts on the back of the unit are flush with the plastic. When my skin becomes wet from working out they drop signal even more. I made a fix by taking some heatshrink and creating a little sleeve that slips over the contacts, helps but still some of the worst signal drop. If you have the newer version they're ever so slightly recessed, this helps but didn't solve the frequent drop problem. Still the worst of all my different TWS solutions. Fiio UTWS01 are nice but the UI (user interface, button click patterns) kinda sucks, but best sound and Bluetooth connectivity, same sweat issue as the BT20S.
