I improved the soldering on my porta pro mod a bit last night, and I made the cables removable. I don't have the two pin iem jacks that I ordered for it yet, so I made my own with some breadboard cable ends and a pair of pliers. Now I can unplug the bluetooth adapters if I want to use it with a cable. It's a much sturdier connection than soldering the wires directly to the pins.
Apparently these bluetooth modules will only work with devices that support BT5.0, so it won't connect to my desk phone at work. I'd like something that supports pairing to multiple devices simultaneously, but this works well for listening to music from my phone.
