SamsungTomorrow has just published an Infographic that shows the ideas and uses of "Samsung Level Link" which is a small Bluetooth fob that can wireless audio stream to anything from headphones to cars.
The idea is pretty simple a switch tells the Level Link if it's transmitting or receiving, then you just have to plug in the old-fashioned 3.5mm audio jack.
When acting as a receiver, it lets you stream audio from sources that lack Bluetooth functionality your favorite corded headset or your car's stereo. The transmitter functionality has potential too you can watch TV with headphones but without cables. Check the Infographic below.
