Further clarification -- this "delay" is called "latency," and it is the 
time it takes for digital processing to convert audio to digital, 
transmit it from the radio to the headset, and for the headset to 
convert it back to audio.

There are (at least) two Bluetooth standards that I'm aware of. The 
older "high power" version has greater latency than the newer "low 
power" version likely to be used in headsets. Both are large enough to 
make it impossible to monitor your own sending.
