I don't use DISH myself so can't answer but wanted to welcome you to Satellite Guys!
P.S. This question should be posted here. The Support Center is for issues with the website itself. Perhaps a mod will move it for you or you can repost there to be seen better.
I am not sure if the poster has a wireless or Bluetooth headset. If wireless it will work. My 4KJs have built in Bluetooth. Added the Bluetooth USB adapter to my WJs. The adapter is still listed in mydish OrderFromStore.
