I am trying to connect my noise cancelling headphones to my Yamaha digital piano with a cable, because Bluetooth won't work due to the lag. My piano has a 6.35mm jack and the headphones have a 3.5mm.
The connector on the adapter I plug into the piano is very slightly too big and the cable falls out, or the sound drops, so I have tried three different 3.5mm-6.35mm cables, but none of them will work with the Sony headphones. Is there a particular brand of cable that works with these headphones?
