This is my idea of the perfect pillow. Plug it in to your MP3 or CD player, and it plays your favourite music - right into your ear! I sometimes have trouble getting to sleep, or wake up in the wee small hours and can't get back to sleep. Now all I have to do is switch on my pillow, snuggle down and listen to soothing sounds. It doesn't disturb my partner - I doubt that he would hear it, and it certainly isn't loud enough to wake him up. Furthermore, it's a very comfortable pillow: quite soft and very snuggly. You can't feel the speaker at all, and the connection for the MP3 player is at the edge of the pillow and out of the way.
ADDED A FEW WEEKS LATER: One drawback I've discovered is that this pillow does make my head hot!! It must be made of some type of filling that reflects heat, so if you are a chilly mortal you'll find it great. I found I was waking up in the night with a boiling brain.... Pity, because falling asleep to soothing music was bliss.
