first of all thank you for these wonderful machines that allow us to enjoy music and these benefits! After a DX, then a CX + EX + P1 + P2 set, I now use a K50 and an S30. I was able to appreciate the successive improvements of your devices.
My question: what is the procedure to be followed to allow the update from AMSv3.0 to 3.1?
Have a good day
