CES 2013 encountered several useful devices. One of them was SleepPhones which is a Bluetooth Headband to listen music.
This is a soft and comfortable head-wearable device with in-built earphones which can be aligned to adjust at your ears. This wireless Bluetooth device can be paired with mobile phone, tablet, smartphone, iPod etc. SleepPhones will be available from April 2013 and will be priced at USD $80.
Previously wired SleepPhones was also available but you needed to plug the earphone jack into your smartphone.
This gadget will be primarily helpful for those people sleeping together who want to enjoy music without disturbing others.
