A good addition
They arrived today and within ten minutes I was using them with my Traveler Pro Series and a Philips SongBird music player.
The cord is a little short for a full size guitar but with a my Traveler it is just right.
Playing with the knobs a bit I got an acceptable tone and was wandering around the house playing.
Worth the price if you practice quite a bit and need to respect the neighbors or a room mate.
The only problem I have with them is that I didn't buy them sooner. :-)
