I've been listening to adventures in Odyssey Since I was in elementary school, now I am 33 and I still love it. I have my son listening to adventures in Odyssey now At five years old and he loves it as well.
I'm so certain that you and/or the people you're buying them for will be so pleased I'm keeping my review short. I bought these for Gifts. They've listened to them every day since opening them. You'll never make a better purchase!
