I'm one of those people who prefer listening to music when trying to sleep. Trying to sleep with headphone is really uncomfortable but I know quite a few people who prefer drifting off with headphone. If you are in the same category as me, you should have a look at this Pillow Pod, it is made of 100% polyester. This Pillow Pod connects to iPods, MP3, CD or a computer. The input is a standard. It will cost around $16.19 - $17.99. The Pillow Pod is available at Target in 4 colors; blue, purple, pink and lime.
