People who don't want to disturb sleeping family members could use a new product from Panasonic that doesn't need speakers or even your own ears: wireless bone-conduction headphones.
They are one of several innovations Panasonic unveiled at the International Consumer Electronics Show (CES) in Las Vegas.
The headphones connect to a TV via the Bluetooth wireless standard and attach to your head like a normal set of headphones. But instead of using your ears, the headphones work like hearing aids by transmitting sound waves through your skull.
Panasonic also showed off a new user interface for its "Smart Viera" TVs, featuring a TV-mounted camera that recognizes the user and sets viewing preferences accordingly.
The Japanese electronics maker also showed off an easy way to send YouTube videos from smartphones to the TV.
