Marc, I'm well and truly intimate with WebRTC. The trouble with IP-based connectivity is then latency involved with packetization. DECT and BT links don't suffer this, but they tend to be bandwidth constrained (especially microphone freq response.)
It's surprising that there are very few headsets with full bandwidth microphone. Those that are, like the DPA D:Fine service, are offered for stage/theatrical performance. They assume separate belt-packs for microphone vs monitoring.

My hack was not bidirectional (it could be), but I suspect that the WebRTC standard could be used on a phone, a small standalone computer or some of the newest iOT micro-controller with Wifi and full-duplex audio. I have no idea how "better" it would be compared to available Bluetooth headsets. And it would not be cheaper... A good start would be to design an Android WebRTC app for your specific use case, and maybe this app already exist.
