Recommend Headphones For Sleep Normal headphones are usually very uncomfortable and impractical to use while sleeping. I've had some SleepPhones for over 10 years now and I highly recommend you give them a try. SleepPhones are specifically designed for use while sleeping, with thin flat speakers that are contained inside a very comfortable headband. You can use them while lying on your side and they also have wireless versions, making them very easy and practical to use.
