I was totally kidding.Yes. There are 2 versions. 1/4 Inch and 4 Pin XLR.
You don't have to buy a new headphone, at all.
You can send yours into Grado or anyone else to be terminated to XLR or do it yourself.
I've done every Grado I own myself or have owned because I run a fully balanced system with the exception of my 325is because I use that with my Schiit stack at my desk which is 1/4".
