Hey Bob, my experience exactly. The Compilot 2 just works and I know it connects to at least 3 devices at one time. I have it connected to my office phone, cell phone, and streaming from a tablet. I get a call to either phone, the streaming pauses while I take the call.
I bought a lapel Mic and plugged it into the Compilot 2. I keep the Compilot 2 under my shirt with just the tip of the lapel Mic showing.
I don’t think they will let the Compilot 2 work on the Marvel, but if they did, they would have the best solution out there.
The Roger Pen can do Bluetooth phone and it connects to 2 devices at one time, and pairs to 7 or 8, so that is an improvement. Roger Pen connection to Marvel should be available 3Q-4Q 2019.
