Very easy to use and very intelligent for such a small transmitter. I use it to connect to my non-smart tv flat screen tv, connect to USB and a headphone jack to audio out. As soon as it turns on from the connection to the TV, it searches for active Bluetooth devices such as headphones. Connects instantly. The only thing I don't like is that the audio starts to lag, but it's imperceptible unless you read her lips on the screen.
