I would go with BlueTooth.. You can get a transmitter from multiple sources (though I've yet to find one I like) headsets (The good old can type) or Ear buds can be had for not nearly as much as you think if you shop places like Big Lots or Ollies (Great stuff Cheap) you don't need the hundred dollar PLUS Jobs with first rate noise canceling (AND i MEAN first rate) They sell for Truckers.

That is not how BT works.

BT receivers must be "paired" to the BT transmitter..

Unfortunately you cannot simultaneously connect and operate multiple BT receivers (IE headphones) from a single BT source (IE transmitter).

MULTIPLE BT HEADPHONES

Q. How can I connect multiple Bluetooth receivers to a single Bluetooth transmitter so that several people an listen to the same audio source on individual BT earphones?

A. You can't. Each earset will operate on a slightly different sub-frequency, so they don't crosstalk, allowing the systems to deliver different audio to the different headsets.

What you need to do is have multiple headphone jacks that you can plug multiple transmitters into. You need multiple systems.

You might look at the popular Big Knob from Mackie or another device that breaks out headphones for cables, then plug your little transmitters into each of those outputs.

What you want to do is very common in a studio environment. Try B&H Photo’s website."

In the OPs situation they are needing more than ONE headphone..

BT also has max pairing limitations, something like only 7 devices but only ONE can be "active" in most cases if not all cases.

They WILL need buy ONE transmitter (source) for EACH HEADPHONE, each will have to be "paired" to one transmitter source to make this work.

Something like this..



for $129 each HERE which features "auto connect pairing" so you will not have to manually pair a dozen or more headphones..

OR will need to buy individual BT transmitters like this..



BT transmitter for $16 for each BT headphone (be aware, not all of these devices are "transmitters" some are "receivers only"..

Then you would need to provide some sort of amplified audio splitter for all of the transmitters which is a whole nuther issue..
