Can you get single ear headphones at all? I find that if I listen to a track with my Walkman ear buds I can follow the bass much better, but then I can't hear my playing, especially if I'm not plugged in. I usually use just one of the ear buds, but as they're stereo I'm worried about missing bits as I haven't got both of them in.
Is there a single mono earbud solution, or any bit of kit that I can plug the output from the Walkman, or laptop, into so that I can play along and hear it at the same time?
