I am looking for a way to connect two headsets to the same iPhone that will work with popular software for audio calls, e.g. Zoom, Facetime, and Skype.
Basically, I am looking to put an audio splitter/mixer in front of the iPhone that would communicate with the output/input devices over Bluetooth, split/mix the signals, and communicate with the iPhone via Bluetooth or Lightning.
To achieve that kind of control I might have to use professional-grade recording equipment.
I found some products that do something similar, each of them lacks some essential capability:
- Diagram 1: Product 1 - no audio output, only for streaming
- Diagram 2: Product 2 - only audio output
- Diagram 3: Product 3, Product 4 - only one headset can have both audio and mic
The "headset" does not have to be a headset in a traditional sense, it could be separate mic, headphones, or even speakers.
I realize that the iPhone allows only one device with the handsfree BT profile to be attached at a time, so a direct connection is not possible.
