I loaded the small device with usb cable> Micro USB provided. It was pretty fast.
Then I plugged into my TV and presto, it's plug and play. Everything worked. I paired with my bluetooth headset. I have been blown away. I still can not believe it. I have bluetooth on my TV! And I'm nobody bothers to listen to the TV with headphones.
I also tried with my classical radio. I connected the transmitter to the radio, I paired by pressing the only button that is (the little red light / Blue appeared). I put an audio speaker in research and hop, I radio in the bathroom or kitchen without having to move my radio. And better, I moved my enclosure in the garden: no worries, I was at 5/6 meters of radio and transmitter.
It's AMAZING. I did not know that such devices exist. And frankly, it gives a sacred facelift to devices without Bluetooth!
