For a given connection, it does not matter whether there are obstacles in the room or not.
2. Connect through infrared port. The advantage of transmitting audio via infrared is the high quality sound. Unlike a Bluetooth connection, the distance to communicate with the transmitter should be significantly less, but this is not always a problem.
