What distances are you talking about?
Mono or stereo?
You could keep all this simple and hard-wired, and run cables to headphone amps at the different listening locations.
Going wireless, a single wireless microphone transmitter can feed as many wireless receivers as you want to buy.
Stereo would require two transmitters, and two receivers for each listener.
Most wireless IEMs(In Ear Monitors) are set up for stereo.
The budget wireless choice would be one of the 'assisted listening systems' commonly used in large worship halls.
All of these options are available in analog format, with essentially no delay.
As a live audio tech, I can tell you that your question likely already has an answer.
Large orchestras stay in time because everybody is using the speed of light for timing - they watch the conductor.
For smaller performing groups, visual cues are still important, and hearing cues of less than 10milliseconds are generally adequate.
Good health, Weogo
