I didn't really expect much for this adapter since it was only a few dollars, but I bought it because of other people's reviews and I wanted to be able to play my keyboard without bothering other people. My headphones fit perfectly into the adapter and the adapter fits into my keyboard, and I can hear sound, but it's mostly just static. No one would be able to actually play with that sound. I would not recommend buying this.
