These can be mounted on a helmet with the correct adapter pack.

I bought these and am holding the Dark Earth model as I type this. These DO NOT have the Nexus TP120 U174 military connector. That line in the description is NOT correct. There is a standard stereo audio jack (the kind used for headphones) for piping in audio from a MP3 player or the like. The picture above showing a cable IS ACCURATE. That it the cable and plug type it comes with (standard 3.5mm audio jack). The instruction sheet that comes with also verified this is a 3.5mm audio jack only. Next. These do have what appear to be standard Peltor mounts and so should adapt ARC rails without problem.
