1. Connect to the audio output of LCD TV's (TX mode). Then I can easily interfere with my Bluetooth headset television without others.
2. Following my old iPod (TX mode), which then also transmits the music on my Bluetoothkopförer.
3. Connect to the audio input of my AV receiver, so that I can send my music from Amazon Music app on my system.
The combined unit is nicely compact and can be anywhere stow away. The battery lasts for up to 9 hours. Anyone planning a longer operating times, can also use the device via USB power from the wall outlet or from the mobile power bank.
With the package includes another RCA to jack and a standard jack cable. The range is very good. Trouble-free to about 8 feet, it always depends on what items are in the way :-). Overall, I am very happy and thanks to the dual functionality allows the Bluetooth transmitter / receiver used flexibly.
