I read on an online forum that 2 people got this to work with their Sony FX6 grip and I can confirm that it works with the Sony FX6 grip converter! this not only works, but saves you ALL manipulation of the grip when it is attached directly to the camera. Note: The cable that came with this unit WILL NOT WORK with the FX6. You'll have to pick up a TRRS extension instead, but these can be purchased online. I am very happy with this purchase!
