Neutrik has been making EMC connectors for several years now to fight against today's noises. I use them but I don't see many other tapers out there using them for field recording.
Check the Nuetrik website for detailed info on their EMC connectors.
These are not that same as referenced in the op. I haven't viewed the video above but the capture looks to me like a digital connector. The Neutrik website will likely have details on those connectors too if they are commercially available.
It says the EMC connectors act as a high pass frequency.
Have you noticed this affect the sound of your recordings in any way, good or bad?
