Haven't played with the wireless Nokta headphones. As I didn't have any reason to. Still have my Deteknix wireless headphones and transmitter. I did at one point think about putting it into a different headphone cup set up to make it water resistant. Have used it with most of my detectors old and new. When I don't feel like using my wired set.

I dig it with a Nokta/Makro product.
