Very handy device, plug straight into the audio out put on any tv or stereo etc then pair device! "Low Latency" meaning no delays in sound which can be extremely annoying with less expensive ones. I used it on my tv to connect my wireless headset but has many other uses. Avantree makes the best long range no delay pairing devices, don't be fooled by inexpensive ones that don't pair or drop signal. As new only used a few times. Best reached by text
