One way radio communcation?

I am looking for something that will let me receive radio communications at no more than 30 feet from the service. I do not need or want to be able to talk back. I just want to hear what someone is telling me. A tethered system would be OK. Has anyone seen a submersible headset or earpiece?

Ocean Technology Systems has a few different systems:

Any idea what they are using?

Sorry, that's not one that I'm familiar with, and I can't say that I recognize anything from the photo either.

For Sanctum on location I think we used the OTS buddy phones. They have ear pieces that clip to a mask strap so one person can yell at a whole bunch of divers and they can't talk back. One issue encountered was that they only receive while immersed so when divers surfaced they couldn't hear anything.

Thanks for the information. I found this:

It looks to be a perfect solution and is relatively inexpensive. Everyone in the water will be able to hear it including divers and actors. I really just need something simple and reliable so everyone can hear action, cut, and direction from the director.

Its an underwater speaker system, we use something very similar on fashion shoot when working in pool, it works very well and the diver has no need to be tethered
