3.5mm plug stereo headphones compatible with digital pianos. These were included when I purchased a Kawai digital piano, but I am selling them because I already have headphones. This is a recent product, purchased about three weeks ago. Although it is new and unused, I opened the package for the purpose of taking photos for the listing.
